- ►The Audi B8 & B8.5 with the 3.0t engine offers one of the best buys on the market right now. However, with the oldest of these cars roughly 12 years old at this point, the engines will inherently need some maintenance.
In this video, Nathan Brown, one of our resident VW/Audi/Porsche experts, guides you through a full diagnosis of the 3.0t engine found in everything from the Audi A6 to the S4 and even the Q5. Covered are various leaks from the water pump, thermostat, and valve cover gasket, as well as failures of the ignition system, PCV system, secondary air injection system, and engine mounts. Beyond that, Nathan touches on the timing chain and timing chain tensioner issues that these engines are known to experience.
If you want to learn more about the Audi B8/B8.5 S4 and S5 other than just the engine, our Buyer's Guide covers what you need to know whether you have just begun your shopping for one, or if you're already a new owner. • Audi B8/8.5 S4 & S5 Bu...

Please tell me what may be the reason for the engine vibration always at the first start. I have already replaced the timing gear, variators, candles, cleaning the intake and the problem still remains. this only happens when the air temperature is above 10 degrees.

Very informative! Love this engine in my A7
Thanks for the video . I have the same exact engine. I have the P305400 code. I was driving Wednesday and at the light the car rattled and engine and ECP light came on . Car lost power and I had to coast to a gas station. The car won’t start . I just hear a click what sounds it could be the starter. Any ideas or suggestions on this P305400 code as I think it’s not allowing my car to start. I also had misfire codes but have had a tune up done today. After that the car started for a few seconds then cut off. I’m at a hole in the road as to what’s going on since the the P305400 Code. Please Please Help! Thanks.
Fcp euro my passenger engine mount broke, do I have to replace both or can I just replace the passenger side engine mount

Thank you so much. Thorough, in depth, but not overbearing. Perfect video
Well done, informative without extra fluff-thank you
We try to skip the fluff and get right to goods 😁
Great video man. Super concise and detailed in useful ways to know what to pay attention to. I'm at 115k miles with mine and still enjoy the motor a lot.
Great video sirs...very informative! I just traded my A6 3.0T for a low-miles (29K) A8 3.0T a few months ago. I'd initially sought an A8 4.0T, or S8, but those cars were $15-40K more, just to get the larger engine. After owning the A6 for a while, I loved its 3.0T engine, and found it sufficiently strong in the A8, which is only 300 lbs heavier than the A6. Plus, my A8 gets 30mpg on the freeway! I plan on keeping this A8 forever, so I'm glad to read comments here that the engine is reliable long-term. So happy with Audi engineering! Subscribed!!
The best and most clear tutorial ever... thanks a lot 👏👏
one of the best videos out there for Audi 3.0 TFSI engine service and maintenance. Thanks,
Wooow what a complete video!! I was in panic because of some issues with my 2014 SQ5, but you just mention everything! Thank you very much, you are a crack!!
This is an AMAZING channel. Thank you guys for your time. God bless
Its only because we have AMAZING viewers! Thank you for the support and glad you are enjoying the videos!
This video is like the 21st century Bible, love it! Thank you for the time and effort, much appreciated. Greetings from Europe

You folks are doing the Lord's work for us simple folks. I appreciate yall. Such great insightful information. Extending the lives of these great cars.
Thanks for the kind words Chev Chellios!
Very useful video! I haven't owned an Audi in over 10 years but I'm looking again.
This is a very good video. 6 months owner of a A6 3.0Tfsi. Next summer I am going to services practically everything. Cooling components, catalysators, supercharger, etc 👍

This video was extremely helpful and full of great tips but the most important thing about it was that it takes ur attention and will not bore you at all until the end. Very few videos are like this. Great job thanks!
Thank you for that, Mahdi!
I have been looking an A6. Your video has sold me on getting one. Thank you,
Glad we could sway you haha
Man this is awesome, great production and kept my attention the whole time. Fantastic insight just what I was looking for -- looking at a higher mileage A7(70k miles) and was looking at things to address and be aware off. Thank you so much!
Happy to help Monsta Moo, that's why we make these!
DUDE YOU ARE FREAKING AMAZING FOR THIS VIDEO.... THANK YOU!!!!!!!!
You R the "3.0T Whisperer". I don't have this engine but still found this video quite iNtErEsTiNg. Thank you (GR8T post editing, photographic quality & direction i.e. I'm ready for my closeup Mr.DeMille :)
My '12 S4 had a recall on the thermostat several years ago, so I had the dealer replace it free of charge. So far, no issues and I still have the "garage princess" which is dressed in Stage 2+ APR, Vossen Wheels, Enlaes rear splitter, APR Big Brake kit, lowering springs, sway bars an Armytrix exhaust which is bananas. It's been a solid car!
Thank you so much I currently have an Audi Q5 3.0T very informative. Going to order gasket kit, thermostat, water pump, PVC Oil Separator.
Happy to help Jose, let us know if you need any other parts! Good luck on your installs, let us know how it goes.
Lol, we have the same car :D
Great video. I dont afraid 3.0 TFSI anymore and im going to buy one. Thanks man
2010 A6 Avant with 183,000 miles on the clock and a ECU and gearbox tune from MRC tunning.
When I first got the car the water pump failed within a month and I almost gave up on it. That was some 5 years ago now and I couldn't be happier I stuck through with it.
thank you for this video ! very informing for a new S4 owner like myself 👍🏻
Very comprehensive video 👍 thank you very much, Im now the second owner of a B8 S4 and its also my first Audi. There's a lot to learn but this definitely lays a nice ground work for what to watch out for. Been working on cars my whole life but never anything like this, absolutely loving the car
Glad it was helpful! Enjoy the new ride 😎
I appreciated the review of the 3.0t. I bought a 2014 A8 (two years ago) and it has performed well. You very accurately explained the initial "rattle" that I hear upon start up and while it goes away in the prescribed time., I may get this looked at just to be on the safe side. Water pump and thermostat will also be serviced as well. With the supercharger off, I may have that serviced along with the PCV replacement since the labor will already have those components off the engine. Great video - glad I came across this and subscribed.
Thank you for these videos, they are absolutely great, for someone looking to own a B8.5 soon, they are super super helpful, and the production quality is top notch.
Look forward to more :)
Thanks Joe! We have more coming for sure. Using videos like this will save you quite a bit of money throughout your B8.5 ownership 😉😅
I own a 2015 S4 and at 55k, I started to get the dreaded tensioner rattle. I replaced them in the winter months with the upgraded unit. These would be easy to replace if you owned the 3.2 v6 but since the 3.0T has the secondary valves on the back off the heads and the catalysts are right next to them, you’ll have to drop the engine down enough to be able to remove the cats so you can remove the bolts from the valves so you can finish removing the back cover to the tensioners. Yes! You will need special tools like the piston stop and a few hand tools to remove and tighten the bolts of the cam gears. A big help was removing the false fire wall which opened up the whole rear of the engine. Good luck if you’re attempting this job but you can do it if you take your time and check your work.
Just got a '15 Q7 S-line Prestige, 100k mi. Still drives like new. Definitely checking everything in this video! Great job!
Right on!
Sold!!! I'm pulling the trigger! Thanks!
Great video. Honestly most of these things go bad on all other vehicles as well.
I have had a 2012 Q7 3.0t for 4 years and just this year had to change the brake pads.
172,000 miles.
Oil changes every 5,000.
And don't run the wrong oil in these, the oil consumption goes way up...lol
It was using about a quart of oil between oil changes and progressed to almost 2 quarts between oil changes then I got the high pitch whistle that went away if I removed the oil filler cap.
I should've known, but these are new to me.
It was the PCV valve.
When tearing it down, the black plastic pipe over the passenger side of the Pcv valve end crumbled off during removal.
I barely touched the coolant nipple on the front coolant crossover pipe and it snapped off.
And while the supercharger was off I found the source of my small oil leak that I had thought was the rear main seal.
It was the oil filter housing instead and it leaks right between the engine & trans. The gasket was flat.
I'm a 20+ year ASE tech so it's not difficult but this is what I found.
About $225 parts online.
Someone had already done intake gaskets & valve cover gaskets so lucked out there.
I have the 290hp version but looking at a tune soon +80hp
Great video. You forgot to mention the flex pipes rattling. Most commonly the result of the motor mounts going bad.
Not being a VAG guy I find this content really enjoyable. After years of reading and seeing it's one of the more reliable platforms, I might try out a B8-B8.5
Go with an 8.5 if you want an S-tronic. The b8 gen has known issues with the DL501 transmission that can become costly if not sorted, especially if you are from NA. In Europe they are cheaper to fix. On the 8.5 facelift all the issues with it were fixed tough so worth the extra money over the 8.
Just bought a Q5 3.0 and this video puts me at ease for choosing this model over the 2.0T! Very informative! Can't wait for more DIYs on this fantastic and fun engine! Keep up the great videos 👍👍
Congrats on the new purchase, T Sal! We'll keep the videos up!
Excellent and precise content! I have this motor in the A6 and no headaches except the pcv valve replaced and 2 seconds chain rattle in the morning on cold starts.
Such a great engine and very easily tunable to upwards of 400 hp.
Thanks!
THAT'S WHAT IT IS. OH MY GOD I NEVER KNEW
Super capable engine jj. Glad to hear yours have been fairly care free!

Good choice!
Very well made video!
I really love to drive Audi...10 year to drived Audi S4 2012 and now SQ5 2020
Thanks for great info! I will appreciate if you guide us how to clean secondary air injection pump!
Awesome video
Very informative. This video is blueprint material for Audi owners.
Glad you think so!
Just picked up a 2010 A6 for super cheap this weekend, from the ticking sound it's making it sounds like it'll need the timing chain tensioners, would like an in car diy on that
Very insightful! Thanks FCP!
Glad you liked it!
Don't forget the oil filter housing seal ( S4, S5 Supercharged engine).
I replaced mine at 75,000. 2011 S4.
Also replaced PCV valve, crossover pipe from the back of thermostat to firewall, water pump, and thermostat.
Big job and long hours.
Great video and very informative. I've a 2014 ( UK ) S4 and have changed the oil and oil filter, spark plugs, ignition coils, air intake, cabin air filter and just changed the centre brake light. How do you remove the supercharger to inspect it's state? You done a video on this? And what is the air intake model ( looks like an IE/ K&N mode ) or is a combo of aftermarket products? Again, great heads up on what to expect. They go like the wind, if serviced properly. In manual and sport mode, they really go for it without any lag; in drive, they're not great, but I guess a remap will change that. Noticed my MPG increase when the spark plugs and ignition coils were changed. Great news.
This video was so good! Only thing it was missing was average price points for parts but other than that very throughout
unfortunately prices can change over time, so what the price points are currently may not be the same in a few years
Nice video !thanks a lot!
Thanks for watching Gustavo!
Thanks for this, I have both a slow coolant and oil leak so hopefully I'll get to the bottom of it!
Oil might be slow burn over time, it’s common on 3.0t. I switched to liquimoly 40W. Still happens though I couldn’t tell you for certain that it slowed or not.
audi`s best engine
I have a B8 S4 and can attest to the robustness of the 3.0T. I think Audi knocked it out of the park with this engine. These make enough power to run 12.9's with the right tires and launch all day long. Put a Stage 1 tune, intake system, and S/C pulley and be deep into the 12's and not worry too much about breaking the engine. The transmissions are another story though. It's hit or miss with those. If you have an early DSG, you might want to keep a spare on hand to change out preferably from a later model. Just putting this out there for those who don't know, a new one is 14K from Audi. Yes, that is fourteen thousand dollars.
Really? I've heard they're generally robust as long as you do dsg filter/fluid/gasket services every 80,000km
Correction, you have a (B8.5) S4 if it's the 3.0T, otherwise if you have a B8 as you claim it would be a 4.2 Liter V8
@@SuperEman500 B7 had the 4.2 v8, B8 has the 3.0t, b8.5 is the 2012 facelift of the B8 also with the 3.0t.
You might be getting confused with the s5 which retained the V8 for a while after the 3.0t came out.
@@SuperEman500 wrong
@@SuperEman500 that’s only the s5
I purchase all my parts for my 16 A6 3.0T from you guys! FCP Euro rocks! nobody comes close to your prices! He is completely correct the 3.0T is highly tuneable, got APR stage 2 tune with supercharger pulley upgrade put on a week ago and from fast to stupid fast!
Thanks Dan! The 3.0T can be a real monster for sure, be safe with that beast of a motor!
Nice! I’m thinking of purchasing the same APR SC pulley & ECU Stage 2, any update on yours after a year?

How much will that cost?
Awesome video, good to know for my Q7...dad style.

Great work and now subscribed 😷👍
Welcome aboard bath1968!
Great video.
Oil filter housing gasket, oil cooler gasket and rear timing covers themselves (on the earlier motors, seems to be better on the newer ones) are a couple more common oil leaks
That was very helpful because I’m looking at getting a 2014 Audi s4 with 77,000 kilometres on it so when I get it I’ll do a health check on the engine and see if everything is good and look at all the service records
Thank you for doing this, it was a great video! Can we see something similar for the B9 S4 platform?
All this content but for B9 will be coming up in the future! Thanks for watching Bakari Howard
Looking forward to a DIY video on the chain tensioners. Could really use that, if I ever have to do it.
@fcpeuro please!
Yes that would be great
Excellent video, sub'd. Questions, if you have a revised PCV installed requiring a reflash, will that cause any issues if a car is tuned?
Thank you
Just put a deposit down on a 15 Q7 S-line with 107k on it. I plan on getting the JHM ecu and tcu tune right off the bat. I may just do some preventative maintenance on some of these items as well so I can have some piece of mind. Great info here
Love my 3.0T TFSI
Great maintenance recommendations.
There is an RKX PCV valve rebuild kit available that works as well. I used it myself. About a $35 part using Viton seals, labor is what it is.
Hot tip if you have that rattle after cold start as the car remains at 1200 rpm check the flex pipes. Early models of the cars with this motor seem to have this recurring problem. The rattle is very similar but obviously comes from the bottom of the car. Mechanics will try to get you to change the cats. Its probably not those....check the flex pipes first
I have the entire exhaust system changed for FOX system with all the cats and stuff and when I cold start i hear loud rattle for the entire time of the engine beign in higher rpm, when it goes down the rattle dissappears. Timing chain was changed in 160K km and now it has 178K km. Do you have anny idea what could it be? It sounds like its comming from the front of the engine not back so it may be supercharger tensioners but it feels pretty tight. ( 2010 A7)
I own a 2015 q7 prestige and that engine seems pretty reliable not issues at 60k miles
That's great to hear!
My cousin recently pyrchased a 2012 3.0T in an S5 cabriolet. (Midlife crisis mobile) Had it a few months but had only driven it on nice weekend afternoons. Stated that it had started to indicate low coolant. Unsure how hot it had run. He had added coolant 'a few times'.
Had coolant pooling all over beneath supercharger. Front of engine had obviously had coolant leaking down it for a while. Water pump spun exceptionally freely, had issue with coolant pipe at thermostat housing, and passenger side 'window' of pcv valve/ oil separator was discolored.
Just had a couple of pulleys, tensioner, belts, water pump, thermostat, pcv valve/ oil separator, several all hoses, the front coolant crossover pipe, the coolant pipe from the rear of the thermostat to the rear of the engine, and the pcv lines from the valve to the valve covers changed.
Engine surged between 800 and 1200 rpm at idle.
He states that it runs great under load.
Has a P0068 and also a MAF/MAP code. Has a sound like a vacuum leak at rear of head on passenger side of engine.
Throttle body and plate, as well as manifold cleaned as far as could be reached.
5 vacuum branch lines checked and are all intact to respective devices.
Shop owner is stumped.
Cousin and I have found several articles/ threads with this problem not being identified after substantial repairs made.
** Pcv valve was O6E black, and was replaced with O6E.
Have heard of issues with alternate pcv valve, cracked intake, and a possible egr valve issue.
Starts right up and runs smooth for 10 or 15 seconds, then starts surging.
Thanks in advance for any thoughts.
That’s Alex Rogan the mythical magazine writer.
Great Video, it would be great if FCP had the parts and tools to resolve these issues posted on the website. I was looking for the timing tensioner shown for a 2015 Q7.
Great info! would love to see this kind of video for the 4.2 FSI in the RS5
Most of it is the same. Thermostat, water pump, engine mounts (funny enough I've already replaced all of those on my rs5) as well as you'll need constant carbon cleans, camshaft positioning sensor goes bad, and timing chain tensioner have a similar issue as in the 3.0T as described. Sparks and coils are also the same as in this vid
@@mattw4211 Thanks. Good to know most of the common issues are easy to fix. I just picked up a 2015 a couple weeks ago with 37k km on it. I've read a couple forums talking about transmission failures which are probably my biggest concern at this point.
@@mattw4211 if you don’t mind me asking how much total for costs ? Been really thinking in pulling the trigger or just get a more care free TL SHAWD. Just not as of a looker as the s4
Great video but do you have one that talks about the transmission issues?
Great informative vid thanx. If it helps, another symptom of a failed PCV is coolant loss which is not visible anywhere until you remove the SC
i loss 1 liters of coolant in 100km and its not visible i dont know the other symptoms its the PCV valve or cylinder head gasket what you think?
Incredibly informative and helpful, subscribed immediately after watching this. Shopping for a 2015 A6 3.0T and I'm a little concerned about the timing chain rattle issue. Some say it's not an issue, some say it can get worse over time as the age and the mileage of the car goes up. Is that something to be concerned about?
Driving a 3.2l FSI at the moment, would love to see a video like this for that engine as well.
i heard about this on the A7
I hade an Audi A6 from 2005 with the 3.2 fsi engine. Mine wife goes to shop and comes back and the car wouldn't start anymore. Went to Audi, repair would cost €8400 they said ! Distribution/ chain problem. It happened arround 255 k kilometers, I don't know how much that is in miles. Bud for me, no 3.2 fsi engine again !
My tech said it depends on how often oil changes were being done
Nice video!
Any tips on transmission problems with this engine??
I have a A5 3.0T from 2014
very good content and Video . can I ask if you have something similar content for B9 rs4 ?
Great video! I'm a staunch BMW guy but really like this motor as it seemingly has no show-stopper issues. At a glance this is a lot more solid than an N54/55 that have a litany of things to fret about...
You wouldnt be wrong in thinking that Stephen... especially when comparing to something like n N54
Yeah just picked up a Q7 instead of the X5 bc there are just too many common n54/n55 engine issues that all cost 2k+ or an entire weekend of wrenching in your driveway.
@@ALE5six1I’m currently shopping a 3.0T Q7 to replace my 08 335i! I’m kind of shocked wt how many people cross shop the platforms
@scott8934 well bmw and audi are pretty similar being both luxury brands from Germany. I tend to like the user setup of BMW but audi's can be more reliable. I've only owned my audi for 2 years so we shall see
@@fcpeuro ....life's irony.....3 years later and I've just acquired an e92 335i N54 DCT 🥴🥴....wish me luck!
You Should have mentioned the silicone gasket on the timing chain cover in the back of the engine. Very prone to leak since it is a silicone gasket right above the hot exhaust manifold. It’s an even more fun job if you strip the small torx screws, speaking from experience they stripped with barely any pressure by hand.
Very good point, thank you!
Could you guys do a "valve cover gasket" replacement on the 3.0t. I have seen a few on CZcams, however they don't really specify the correct bolt tightening sequence or proper torque specs.
I would love a video like this on the SQ5 3.0 tdi (V6T) engine! Also mention the wastegate valves that start leaking on the turbos,.
I noticed my waste gate valve is lose, which means the turbo has to leak boost. But not enough yet to trigger the check engine light. Car is under warranty, what should I do? Would hate for it to trigger the check engine light after warranty expires..
Have you ever done a video like this for the V10 Audi S6?
Great, more work to do
