You went to a scrap yard to find out how other people designed the problem out! So much effort. Well done, I appreciate your time. Subbed. Good luck!
If only Tesla engineers had done the same.
My favorite part!
I don’t even own a Tesla but this video is one of the best DIY car care videos I’ve ever seen. Great detail and an excellent walkthrough with every single aspect.
Agreed. I'm currently shopping for a Model 3, and this is the most detailed video on "cabin funk" I've seen on CZcams.
Thanks for the video! Finally some good information on why my Tesla starts smelling funky and how to fix it! Awesome!
ElectroBOOM?
Wow didn’t expect to see you here lol
Second that! I'm gonna fix the problem by continuing to avoid Tesla. After watching this video I won't even put my nose into a Tesla. This is yet another piece of evidence Tesla is designed by a bunch of clueless charlatans and dilettants with no business being in car manufacturing.
It needs a plasma air cleaner! Obviously!
Also for 42k € to 51k € car , I think , such a fix should be done by the manufacturer free of charge.
just add some eyebrows under the trunk :))
This is OG YT vibes with modern camera work. Straight to the point. And bravo for some of those angles 👀👀 this was very informative. CZcams algorithm blessed us with this
Wow! Super-complete analysis. Unlike a lot of videos, you get right to the point, you give markers to skip ahead, and you edit out the tedious bits. I had no problem watching from beginning to end because you didn't waste a moment of my time. Kudos!
@5:25 He could highlight this part of the video as being the money shot, and I agree it's a very worthwhile video. Good information, helpful to make decisions with
How does this guy not have 50k subscribers yet?? Great video.
i think because this is his only tesla video :) focus on this and numbers will explode
Agreed this was well thought out 😅
Explains a lot. Tesla doesn’t have the years of experience others have. That’s why they always had quality issues.
He doesn’t have 50,000 followers because Teslas are like transistor radios you don’t service them.
Was thinking the same thing, great video!
Something to add: it's definitely not just the rain and water intake that causes the smell. I live in dry arizona and the smell gets bad in the the summer when it's 120° and 0% humidity. There must be some sort of condensation build up somewhere just from normal A/C usage as well.
Yes, I was hoping this would be addressed.
Sounds like a software issue, as long as you’re in Auto mode there should be proper cool/dry cycles not unlike a defrost cycle in your fridge. I guess that’s the problem with a california car company, no sense for the edge cases 😅
@@H0neyGh0st They are a Texas car company now.
@@Zero-lh1rb Oh yeah I forgot about that lol
I would suggest not leaving the car AC in recirculation mode. I know it cools more efficiently but it also creates a lot of moisture stink in the condenser. Let in some outside air especially before parking it.
Probably one of the most in-depth, informative and interesting automotive repair videos ive ever watched. Looked into not only what was happening, but WHY it was happening and instead of a bandaid fix you actually source the root cause and try different solutions after looking at what other manufacturers did to prevent it. Fantastic video!
Super thorough, complete analysis of the problem WITH several suggestions for improvement. Loved the camera shots inside the duct to show what's actually happening. Seeing is believing. Also loved the junkyard benchmarking to see how other automakers have addressed the issue. Thanks for going the extra mile here and providing some solutions with before/after empirical data to back it up. Great work!
Just a great video. 🤩
A very thorough and well done video!!

Hey there, this video was very well-made. And easy to follow even with its length. I give hats off to you man. I don’t know how you’re not a giant CZcamsr yet. You got the GLW AND you can make good content. Which is a very rare combination.
All great information. One thing I would recommend is if you install the new gasket, Do Not! cut it to length immediately after installing it. Leave it long so it can fully return to its relaxed state.
I just paid a lot of money to Tesla for a service to get rid of the smell, now I wish this video was available before I went. Thank you for doing such a great job.
It’s ridiculous how much they charge for this
When I thought something had crawled into my HVAC and died, I also set up service with Tesla. They said it would be something like $225 to replace my filters and spray coil cleaner in there. Well, hell... *I* can do that. And I did. For the price of filters and spray. They didn't even consider that anything else would need to be done. And of course they were correct. Clearly they know there's a problem and how to fix it.... for a price. :sigh:
Don't worry the smell will be back. Mine shows up abt every 3 month
Lol Tesla owners can’t even do the most basic levels of maintenance or troubleshooting and then wonder why they get ripped off at the dealership. They know you’re too useless to do anything but pay them what they’re asking.
@@danielwatson5595Dude, lots of modern car owners don't know anything about basic car maintenance. Myself largely included. It's not that they are dumb or lazy. The world is just very busy now a days. But all that said, look how many are here learning. Smarter more informed consumers are good for all of us. So try not to dump on people who are learning. Just my 2 cents.
The best way to fix this is to alter the design of the duct. You can put a plastic baffle inside the duct that doesn't allow the water to go into the fan intake. This would be cheap to do in the aftermarket and much more effective than a gasket. Changing the fan software is not a good idea as you sometimes need defrost when it's raining. And low speed defrost is useless.
Is there an aftermarket replacement?
why would they. dummies will just keep buying them anyways.
Define cheap. Injection molds aren't cheap, and neither would be the labor to fit a specialized part into that duct. Removing the duct entirely would be a better option imo. It's an electric car so it's not like you need to keep engine fumes from entering the cabin, having a duct to outside air isn't really necessary.
I guess technically it would increase the Teslas ability to drive through flood waters, but I don't think it happens enough to be worth it
I was going to suggest the same since water did start getting on wires and such with the funnel apparatus removed. Add a modified wall, in the channel chamber, right before the air cabin filter, on the firewall side.
I thought the same thing myself.
You could superglue or screw a baffle (plus silicone bathroom sealer to stop water bleeding down through &/or passing screw fixings, hitting any electrical connectors outside the shroud) that rises higher than that little lip around the drain hole. Job done. That gasket is overkill. Also, I would think the gap on the OEM gaskets is deliberate to either allow better airflow into the cabin, or release air pressure from under the hood at highway speeds.
This guy needs his own TV show
For those with with biodefense mode (15:20) : check/replace those filters in the frunk (aka not the cabin ones), especially if you've tried the usual stuff (replace cabin filters + coil spray) + those filters haven't been replaced recently, this actually worked for me!
I honestly didn't know there were filters there at all lol so thank you for that! It's interesting how moldy/heavy those filters were since they're sealed (rainwater shouldn't hit it like you said) but... I've had my car for 2 years and never swapped them 😶 so it's probably just trapped moisture/stuff from normal use?
Either way, thanks so much for such an amazing effort diagnosing + documenting this problem! These videos were really entertaining and satisfying too, I totally see why lots of non-Tesla owners enjoyed these videos hahaha
Fantastic video. Excellent forensics of the problem and cause. Brilliant options offered. Great job, Adam!
15:40
The fact that you mentioned differences on early Y’s, is amazing.
Most people skip over details like this on early models. (For example, early Y’s have holes under the emblems and no “C” shaped brake lights.)
Also, I’ve read on forums that an unofficial retrofit is possible by ordering parts directly from Tesla and adding the holes into the trim yourself. Some of them were even able to request the actual software to “enable” the mode on the screen. Would be interested in seeing someone do this 👀
I just want to mention that the stinky sock smell does affect bioweapon defense equipped cars as well.
@@paulg8065yes, I was so hopeful while watching this video, and then he said that part. I have a '23 MYLR7 and it REEKS.
@@paulg8065I can't imagine the defense value against actual bioweapons is any good if it can't defend against... mold?
@@TheLukasDirector AFAIK the HEPA filters are only active when bioweapon defense mode is turned on. Otherwise it just filters through the cabin air filters.
Question is, will that trim piece work for the 23 MYs?
One of the most comprehensive DIYs I have watched in awhile. Great work! I added the gasket to my shopping cart tonight.
I appreciate the attention to detail and your ability to effectively structure arguments/content.
I have a 2022 Model Y. Certainly has the moisture issue. Cabin definitely smells after the car is exposed to the rain. Crazy to me how Tesla is acting like it isn’t a design flaw. Great video!!
My 2022 model Y (Which has the HEPA filter Biodefense mode) also has the nasty mold smell. 🤢
Lots of effort to uncover the bad design choices, that was covered up by smart but incomplete workarounds by Tesla. Not only you've uncovered the potential design issue, the fact that you"ve suggested multiple solutions is truly ingenious👍👍. Just wondering, if there could be a small 3d printed flow diverter tube(more like a periscope with row of holes on the bottom, to prevent accumulation) that could be fitted over the drain hole. It should cut down significantly on water pulled out of drain hole. Also a nylon mesh covering on main vent could help with water splashes in the intake duct(might need occasional cleaning though). Just some 💭. Excellent and thorough investigation.❤👍
one of the most informative tesla videos out there. you've found your niche please keep them coming!
Something I learned Way back in HS auto mechanics, to keep mold from growing in your system, open your AC RECIRC when you get home. That will allow any water to drain out. Also keep it open for awhile when you first start driving. No more stink in the cabin. Ive had mine for 3.5 yrs, no issues.
Incredible… Concise. To the point. No funny banter. Easy to follow and understand. Fantastic video! Thank you for sharing
Amazing video. I don't own a Tesla but I've rented several, and a couple had this issue. The air stinks for 4-5 minutes after starting the AC. I also imagined it had to be something in the filter, but since it was a rental I didn't look much into it.
Amazing investigations, good solutions proposed and you even validated them. Thank you!
Talk about top tier video! Never seen anyone go into depth and self research like this. This is amazing work! Subbed
Thank you! This was one of the best Tesla model 3 problem + solution videos I’ve seen! I had replaced my filters with similar type that had an activated charcoal stage, and it seemed to help, but like you pointed out, once those filters get moist, they eventually get stinky again. I also hate how the car is always running the fan after I’ve driven it, and now I understand why (it’s trying to dry the filters). But where I live, it’s hard to dry anything with 80%-90% air humidity!
Please make more Tesla videos like this one. Very good information here, I almost felt like I was looking at a Tesla engineer working on product improvement.
In depth root cause analysis, problem solved, great summary and very well put together… professional job! Thanks Adam and keep up this good work.

Amazing video! I loved the thorough analysis with videos of what’s happening on the inside and detailed testing and explanations! Please make more videos like this about Teslas. Next ideas: at home charging setup, installing towing hitch, brighter trunk lights, best aftermarket tires, roof racks, etc. Thanks!
This was a super-helpful video. I really like your scientific approach to the issue. Your camera work was also really good. I have new cabin filters ready to install, but I’ve ordered this seal to put in first. Thank you!
Another free solution is to enlarge the cutout(or multiple sections of small cutout) at the bottom to allow all the water to flow out. Since this is not an ICE car, the mixture of air coming from the top vent and also the enlarge cutout would be ok(no combustion). My car started to smell a bit so this is what I would do based on what I see from this video. Buy the gasket kit, change filter and clean the evaporator. If smell comes back in a year or so, I'll create a bigger cutout or multiple small cutouts along the way to allow water to drain to out before it even hit the last section.
Great video BTW...good job :)
This would be my suggestion also. Enlarge the water cutout. Make it go all the way under the bottom pretty much.
Wasn't even searching for this, but one of the best videos recommended for me in my feed in a long time. Very thorough and well done! Thank you
I'm impressed with how thorough you were in this video, brillant work Adam!
Good video! I just got a 2020 model 3 and noticed that it smells bad when the air kicks on high, it’s only for the first minute or so but definitely noticeable!
Thank you for such an informative video! During a recent cabin filter replacement, the Tesla technician sprayed quite a bit of Simple Green into the area where the cabin filters go, and the foul odor smell disappeared. Your video, however, tells me how to prevent the smell from returning - thank you again!
Great video and the way you chase and demonstrate the problem is spot on, rainy day with air working and wipers on
Great video - love the detail and how you show the nooks and crannies. THANK YOU!
Wow! Kudos! That’s the most in-depth analysis of troubleshooting a problem that I’ve ever witnessed, and you’re a great explainer! Thank you! Cheers 🥂
Thank you for this! I did the AC coil cleaning and then put the same filters back in thinking it was the coils and the smell was gone for a day and then came right back. I was absolutely baffled. This explains so much!
This is it, this is the most comprehensive breakdown and solution to this problem I've ever seen in the 5 years I've owned these.
I love how information dense this is cut. Thank you!
Great production and edditing. I love the way you have a completely different shot with each new thought. good pacing as well. jumping from thought to thought.
You have to remember that in place with 100% high humidity air already carries water, A/C is working overtime and condenser is covered with water droplets, filters are also completely wet in such places. The gap in condenser is a major design flaw.
I have a car with the exact same setup where the filter sit next to the evaporator yet no bad smell.
No because the air presses the water to the other side of the evaporator. So this is not an issue. But, depending on how the draining in the bottom of the evaporator is, it could be a problem that the filter sucks up if you get water standing there.
What air pressure when AC is off? This happens in high humidity areas when you turn ac off water condenses on cold coil, moves to filter.. @@Xanthopteryx
Just wait @@1943vermork
@@teslascoop2177 Fan moves air from filter side to condenser side and thus also forces the water to the other side of the condenser, where the filter is not. If the AC is off then water will not condenser on the condenser since it is not colder than the dew point of the air entering.
WOW this channel is amazing! seriously keep it up. This will be one of the big ones!
Thank you so much for going through all this in depth! The guard that attaches to the hood did the trick for my Model 3. It was getting to be a really bad problem and I was at a complete loss for fixing it.
This is fantastic. Thank you for doing this in depth investigation. This has been driving me nuts for years!!
Amazing video. I suffered from this smell, and your video really helped me understand why!
This is the most professional and informative video that I've seen in a LONG time. Well done!
What an awesome, well thought out video. I’m subscribing to your channel because whatever else you do, has to be good! Thank you for putting so much time into this…wow, I’m so impressed!!
I dont even have a Tesla and still feel that this video was very helpful and well researched.
It's helpful because it shows why you shouldn't buy one.
Thank you for doing all this and sharing it. I too, thought that the moisture was coming from the evaporator, even though I could tell that the funk was coming from my filters! The power of suggestion is strong! I do wish they'd just draw the air UP with a U-turn on the intake. Facing the air intake UP has always seemed like a failure to me on all cars. We should be using gravity in our favor, not fighting it!
I'm amazed to hear about anybody who says the air is somehow "restricted" after installing the gasket you show. There is plenty of free air all around the hood that does not seal to the body.
Exactly, if you put a piece of plastic compleatly blocking the up facing intake and expand the "drain" hole to take the air in that way I think it could do the trick, it's not like a tesla needs to avoid engine fumes like a ice car. This is a design relick from that time that Tesla missed, unusual for them but it happens.
@@agw5425 At that point, it is probably easiest to just remove that intake as Adam mentions. I think the only issue with drawing the air in from below is what happens when driving on a dirt/dusty road.
Let's put a snorkle on the Tesla intakes! :-)
@@darellddthe snorkel comment had me let out a laugh 😂😂
@@darelldd If the filter clogs up to fast you can put a course sponge in the duct as a pre filter and just rinse it once in a while. Most driving don't render that much more dust below than above the same car. The main reason to keep the duct and block it is to stop water entering the area at all, you would need the extra gaskets of cause.
Can you the they guy is an engineer?
Wow! What a great and thorough video. Appreciate you making the effort to do this. Bravo!
Super detailed, great production quality. Love the additional camera angles!
What a joy it is to see the scientific process at work! I loved your suggestions and even more seeing the GoOro videos of water movement. Excellent video!
This is a very well put together video. Thank you for this. The logic, the clear but simple explanations, the mountain of evidence to support your claims, I would bet money you are an engineer! It takes one to know one. You really should get a roadster for saving Tesla hundreds of hours in root cause analysis.
So detailed. Appreciate all the work that clearly went into this video. Hopefully Tesla sees this video and makes the software changes you suggest.
Amazing video presentation , all boxes checked and solutions provided .
kudos to you for a video well done . Really helpful 🙏🙏🙏
Very thorough examination of the smelly problem and recommended solutions. Terrific coverage! You have a New Subscriber now.
This video is great. The one issue with this being completely accurate is that I and others have noticed this issue without rain. The most pronounced it has been for me was in extreme high humidity with the air conditioning running. And I can see that the drainage from the condenser isn’t perfect. Likely leading to wetting of the bottom filter.
Agreed. There's not much chance that rain or washing is getting my filter directly wet. But humidity seems to be a big issue. My issue comes right at the change of season when humidity goes up, right when the filter is dirtiest from summer driving in the dust and pollen (and fire smoke!). The solid solution for me seems to be to change the filters every November.
Last I checked on this about 8 years ago on my BMW, it had absolutely nothing to do with what is being discussed in this video. It is actually some EPA/EEA guideline which forced vehicle manufacturers to stop using mold growth inhibiting paint on the automotive Air Conditioning evaporators. As such every vehicle after the early 2010s has been suffering from this very same mold smell problem, and there is nothing manufacturers can do about it other than offer you a temporary solution in the form of a cleaning. Supposedly it has something to do with the mold growth inhibiting coating that had been used for many years all of a sudden being considered to be toxic for the environment. So in short we have all been forced to suffer with moldy smelling automotive air conditioning since. Pretty sure that if you have the same Tesla and live somewhere warm and humid, you will be experiencing the exact same issue even if water never gets into your filters like it does for this person. In short, good luck and learn to live with it unless you want to go pressure the manufacturers to find a non-toxic alternative. Lastly, in other words… the issue is MUCH MORE complex than what this video leads you to believe. Happy youTubing!
New sub earned Adam! Excellent video and the most comprehensive solution out there - the camera shots of the water intrusion is a slam dunk.
WELL DONE !!! Great camera work, very clear explanations/troubleshooting - Thanks ...
Very interesting video. I have a 2019 model 3 and yes have replaced the air filters a few times because of the smell. I did not know the root cause of the smell. What I take away from this video is that the cause of the smell is water getting down in to the filter. So if you can avoid water getting down there as much as possible (I.e. closing the flap /using recirc during washing the car and using recirculation mode when it is raining), you can avoid the smell almost completely without having to use the evaporator cleaner.
Excellent video Adam! 🤩
This is clearly a design fault Tesla should fix for free. At the very least the software features you mentioned.
Going to get the aftermarket gasket you’ve suggested and change the filters in the meantime. 🤞🏼
Subbed. ❤️
The video is very helpful and well montage. Well done . Keep making this kind of videos on different subjects and issues u might face in future. Am subscribed ❤
Just subscribed after watching this video! Thank you so much for helping me (someone who doesn’t know much about automotive tech) understand HOW this problem is happening. I loved when you collected data on how other manufacturers address this issue!
You're welcome! Appreciate the kind words!
I think the better design is to put a 2" or 3" lip in front of that drain area in the duct, perhaps in a C shape towards the front of the hood. However, I'd be interested in knowing why hood gaskets isn't continuous from the factory. Hopefully the current models have this problem corrected.
Thanks for the great guide! I ended up taking out the intake on my 2019 M3, but there were a few differences that make your 2021(?) easier to work with:
- the 2019 intake seems to be a 3-piece affair: an irregularly shaped box adjacent to the fan, a detachable vertical portion, and a slightly different "funnel" at the top with a wide flange on the driver's side (presumably to protect the positive 12V battery terminal, even though that has its own rubber cover)
- 2/3 parts come out easy, and the funnel can be reattached to shield the battery and also secure the surrounding trim pieces together (as it has 4 pins that connect into different pieces)
- the innermost part is nigh impossible to remove, even with the frunk removed. Something to do with its weird boxy shape and perhaps a different layout of mechanical components in the 2019. After rotating it for the better part of an hour, I dremeled it into 2 pieces and removed it.
The shape of the 2019's intake seems to be a bit better when it comes to water, as the drain hole exits much further from the air intake and is also at a noticeably lower "sump" point - water has to travel up a reverse slope to get to the fan. But I'm about to replace my cabin air filter again, and I just don't want to deal with any contributing causes that I can avoid.
I had the same problem with a 2020. I left the inner part attached to the firewall for now but unclipped the lower part that makes up the scope upwards. We will see how this goes but already looking at also adding a hood seal so that water won't drip onto the AC compressor, etc.

First time viewer, great professional video and review, I purchased the new gasket for both my 3 and Y
Excellent video, Adam. So much great detail, easily explained, and loved the mini science experiment to demonstrate the potential or actual cause of the odors. I have a Model S, so I don't think this applies to our cars, but good info to have either way.
You'd know when you get that fishy smell. Usually take 3 to 4 years in a normal car with regular AirCon usage.
How is your air intake different on the model S?
This was amazing! The quality of this content was fantastic - learnt a lot. I have had smelly filters - the video showing the drain hole actually ends up as an intake also might explain the strong exhaust smells every time you come up behind a gasoline vehicle (2019 M3)
Do you know how to fix this? I get the smell in Model 3 more strongly than in an ICE car. It is enough to briefly drive through smoke and is perceptible in the cabin. I hate it and would love to find a solution.
@@Yelonek1986 I put it into recycled air if I see it in time - it feels like it scoops air up from the ground, not the intake at the top, maybe my duct has come loose. But no - I don’t know how to stop it.
Thank you, Adam - this was a fantastic video. I dont know what else you have created, but your work is great! Thank you for creating this! This is information that I needed to know!
I don't just subscribe to any channel but with this quality of videos, you got my follow. Great job.
Great analysis. I’ve had the problem multiple times and replacing the cabin air filter worked, just like you mentioned. However, I had a road trip in cold weather in pouring rain, and I had to drive 2 hours in the pouring rain. this design flaw led to water getting into the resistive heater element and shorted the circuitry. This led the car to pre-emptively shut down to protect itself and had to get the car towed and heater replaced.
in a downpour I'll be sure to recirculate air
and for sure you will mist up the windows and won't be able to drive anymore @@richmondparkers 😂
@@anubaral Ever hear about AC?
I've had mine for years and never had that issue in all kinds of rain.
You are a GENIUS, not only in your thought process but equally in your execution and testing. Take it from a mechanical engineer, you just out engineered all of Tesla's engineers. I hope you make millions of this video and/or franchise as a business or better yet into a marketable kit. I can help with that. Great job!
Adam, I really like the way your videos are made. Obviously you've been doing this for a while. I had to Subscribe after seeing this video. Great stuff!
Love this video! I just ordered the parts right after finishing watching. Thank you!
I had a 2018 Model 3 and the AC never made it smell. But, one trick I learn a long time ago with other vehicles is to turn off the AC a few minutes before ending my drive and running the vented air on high. This helps dry the moisture off the condenser coils, which causes mold that is the cause of the smell. This is a thing with any AC unit in vehicles and buildings. But yeah, it is more common in a Tesla than other vehicles due to how they designed the air duct.
I get your point but your test really focused spraying water into that filter duct with the hose. That's not exactly how it would happen with rain in most places, especially while driving. But I agree that Tesla should have tested this more and fixed it. I like the hood gasket idea, again something Tesla should have come up with. They also could have put the duct facing down, instead of up. You could mod the existing duct by blocking off the top and cutting an opening in the bottom for the air. But the hood gasket is probably and easier fix. It baffles me how all the supposedly smart people at Tesla, with all the testing that they do, never discovered this issue. Or maybe they did but management ignored it.
But good job looking into this and figuring it all out! And I agree that when it's raining use recirculate mode, even have the AC with the heat on, to reduce the moisture in the cabin air.
👏 driving extra to dry out is something I do on my ‘18 M3P, and it only gets me that far. I think a middle ground is to get the air to flow and water to drain with the duct in place. While I think on the onset, turning it upside down is logical, I guess that the same air pressure and flow forcing water into the car would affect the car’s drag coefficient and impact its range if it were upside down.
One thing on all other cars he showed was the intake being on top. ☺️🤔
I agree with you about spraying water on the windshield and past the windshield wipers, is not indicative of real world. In my view it is not nearly enough water. I live in the tropics where it rains 22 inches in one month. Stuck in traffic, in a monsoon rain delivers significantly more water than from the spray in this video.
Don’t know why I watching this video as I have a model Yp with the HEPA filtration system.
I believe that teslas have a desiccant installed specifically to address this issue
@@gir1258 That really won't help if it is also soaked.
Great video! As you showed at the junk yard, most cars have a cowl. These typically have a smallish input, large drains, and a large collection area that would require a large amount of water build up before it could enter the cabin intake (note it has to handle this during acceleration, braking, cornering, angled roads). Effectively these are dorade boxes en.wikipedia.org/wiki/Dorade_box . Tesla's 'dorade box' is missing the vertical barrier and that is letting water flow into the cabin intake. A simple baffle should probably fix this.
I'm curious: after taking out the 'cowl' did you try running through deep water at speed to see if the water would splash into the cabin intake?
This is the best video I've ever watched in CZcams. Respect
I don’t have a tesla and I am not planning to buying one
The detail on this video is incredible. Well done. Super useful!
Great video..Note in that early 2020 Y (similar to the 2020 3) the drain hole is below a sump (raised bit).. seemingly that changed for the models with the new frunk design (some point in 2021 or later)
That seems like a much better solution.
But my takeaways .
- Use Car Wash mode when washing car, particularly in got days when a/c might activate
- Dont run fan on high during rain
If that doesn't work consider the extra stripping.
Yup the newer models don't suffer from this issue nearly as much. I think there's also some software tweaks that aim to dry to the radiator coils when you park the car, but I could be wrong about that
Great video. Was wonder If you pull air lower down you might get more smog or air pollution lower to the road. You will also get more dusty air if you drive on dirt/desert roads.
Thank you so much for this video! It was driving me crazy on why my 2021 M3 was smelling sooo bad! I tried everything but didn't know it could have been the cabin filter! Great video!
Great video! One of the best I’ve seen about this issue! Thank you!
There's an aftermarket cover for the intake duct that does a fantastic job preventing leaves from being sucked into the duct. That would probably help with this some as well.
And now that I'm thinking about it, I've had it in mine for a few years and I haven't noticed any odor. Went two years between filter changes last time too. Suppose I've also been using carbon filters the last few years.
I did get a smell despite that cover.
Very interesting and well put together topic, I had this with my 2020/21 M3LR, Tesla replaced the Filters and used a machine to defume the A/C condesnsor under warranty, but the evidence presented in your video puts doubt on this as a long term solution. I'm UK based but will definately will see if I can get the aftermarket gasket and give it a go, thank you.
Very good systematic approach!👍🏻

Very impressive video, lots of information to deal with the problem. Thanks for sharing.
This video is so appreciated and made me subscribe. I've gotten as far as you. I always suspected the filters. I also saw some replacements framed in silicon or plastic over the cardboard, and maybe their theory is water at the bottom of the compartment that soaks the bottom filter. I'll be removing the gasket, getting the Wix filters, and calling it quits and my detailer next. I found some for $11 during the last replacement. I was settling into replacing them every three months. This also explains why, once present, it gets more potent when it rains, and the system is not set to inside air only.
The reason the sealing strips across the hood, where it meets the base of the windshield, it isn't continuous across is because that area becomes a high pressure zone when driving, which assists the HVAC system when drawing in air, if you leave the continuous rubber seal in place you're forcing the HVAC system to draw air from areas it wasn't designed to be drawn from. This design dates back to the 30's or 40's when people actually died from the air being drawn into the heater near the front of the vehicle when the vehicle ahead is exhausting nearly directly into the heater air inlet. It looked as though the water that does get into the inlet is draining right onto wires and what looked like the wiper mechanism, the chute prevented that, at least put something over those areas to direct the water so it doesn't pour onto the electrical devices.
I'm having difficulty with the fluid dynamics here. What would create high pressure in that area between the hood and the windshield? If air is being dragged UP the windshield at speed, a first glance would have me assume that it creates a low pressure, and vacuums air out of the area?
Very smart diagnostic process. I enjoyed this video. Thank you
Awesome vid 👍🏽 thanks for the helpful information. You make great content
