Very nice step by step video, but I would like to make note that you do not need to remove the intake resonance manifold for this job. You only need to remove air filter box on bank 1, and remove the ME (aka Engine Computer). Once the ME is removed, you remove the dipstick. gently and carefully pull the thick harness that blocks cylinder 6 coil up and over the dipstick tube to give you extra space to pull that coil off. This job only pays 1.5-2 hours if you brought it into a dealership to be diagnosed and repaired. We do not remove the intake manifold as it is a lot of extra work. However it does not hurt to follow this method as it is a much safer way to perform this repair, just takes more time, and sometimes the thin vacuum line on the back of the motor can break or split even if your careful, and you will get a CEL if that happens.
i need to replace the coil on #4 (front, driver side). sounds like i only need to remove the ECU to access this coil? do i need to disconnect the battery before unplugging the ECU? Thanks
I used to work at a Benz dealership years ago and thats when the M276 first came out. They always said whenever disconnecting a control module, to disconnect the battery to avoid any frying of the internal board. I could be wrong though. I noticed he didn't mention that in the video.
Thank you for the video, it was excellent resource for tackling this somewhat formidable task. I just completed replacing the plugs and coils on my 2012 E350 convertible and have a couple of recommendations to pass along. First, if the coils are original, bent needle nose pliers are not a nicety but a necessity on this job. My 13-year-old coils were fused onto the plugs and it took a tremendous amount of cursing and reefing to break them free. The bent needle noses were the only tool that would grip the little pull tab with enough force to remove them. Despite only gripping them from the tab, I had two of the coil shafts break and it took some effort to pry the pieces out of the spark plug chambers. Regardless of whether they the coils break or not, I strongly recommend spraying compressed air in each spark plug chamber after removing the coil but before removing the plug to prevent plastic bits or other debris from entering the cylinder chamber when the plug is removed.
One of the very best How To videos on cars I have seen yet. It's one of the many reasons why I buy all my parts from FCP. Easy to follow and didn't skip any steps. Well done!
The best step by step instruction to remove the intake manifold on M276 ever. Now I am confident that I can replace camshaft position sensors to stop oil from leaking to wire harness and migrating to ECU. Thank you so much.
Just an FYI, This job CAN be done without removing the intake manifold. It isn’t easy but it can be done. And if you use a wobble socket by CTA tools it’s a breeze. Can be done in 45 minutes start to finish
@@JRounsborg You can do it without taking it off but I dont think someone wants to have a leaking coil, broken wire tabs. Doing it with manifold or without will take same time.
@@artyomkim7577 a leaking coil? I’ve never seen a coil “leak” I remove these coils daily. I work for MB professionally. It doesn’t save any more time to take the manifold off. The only advantage is room. But then you have to replace the gaskets. Not worth it at all IMHO
What an aboslute GREAT video , I don’t work on too many Germans and was hesitant to even take the job in. but this was so professionally done. i can’t say enough good things, dealer quoted $1500 , i came in at $950 and saved my customer money and made a $600 profit thanks to this video
Thank you 🙏 bro for the details and walk thru, life saver - just did my #6 coil over and this video helped a lot, was able to get all the stuff out from the driver side and get busted knuckles changing the one in the back. Saved me $650 mechanic labor, $80 coil over.
For others: Replace them all together. You don't want to do this again in a couple months when the next one goes stupid. After all: they are all the same age and mileage.
Thank you a million times!!! Had a misfire on cylinder 4 and figured i would just do all of them and the air filter as well. Your step by step process was well documented and I got the job done without a hiccup!
@@fcpeuro any recommendations on cleaning intake and valves on these vehicles? (w/o removing the head of course) While replacing plugs and coils i got a glimpse at them and they are pretty caked up. My GLK is at 93k and im sure it would give it a breath of fresh air, at the least decrease op temp. Any advice is appreciated, thanks again!
Excellent Tutorial. I did this on our low milage 2015 some time ago. Note to others. DO the Coils as he recommends. I ended up having to pull Intake a second time. IIRC the Dealer wanted $1400-1600 to do this at that time.
IMPORTANT! Michael didn't say this, but his work in the video verifies it. !!!For the spark plugs!!! !!!You have to use a torque wrench and set to the correct torque!!! Mercedes designed the heads in a way that the spark plugs must be indexed when installed. The only way to do this is by: 1-Only use approved spark plugs. 2-Only use a torque wrench set to the correct torque.
@@JettaRedIII I think I saw about the spark plug indexing on the channel of an Asian gentleman that works on his own Mercedes at home. I can't recall the channel name, it might be numbers or something unique, and there's what appears to be Chinese script in the video titles. You may have seen his videos, at the beginning of every episode, he changes into his shop clothes. He doesn't speak in the videos, they're all done in captions, in English.
Thank you guys so much for this amazing video. I bought the coil and plug kit and some tools from you guys and got the tools so fast. I got this done and saved over 2 grand from what the dealer quoted! I cannot thank FCP Euro and you enough for enabling us DIY'ers! My GLK is back to working perfectly!
Just did this job 3 hours. Probably can do it in 2 hours now. -Do NOT need to take off the intake. -wire clips are a pain to get off. I learned a trick by the time I got to the last one. I would push down to release and while pushing down I would stick a nail on the other side to hold it in the released position and then use a screwdriver to tap it out. It worked great on the last clip. Too bad I didn’t do it on the previous clips. -last 2 spark plugs driver side a big pain.
Because of the comments, I ended up not taking the manifold off. If you do it this way, I recommend disconnecting the air intake adapter. I just un bolted the air box and flopped it out of the way, resulting in it splitting. Cost about another 80 dollars to fix. Hardest part was getting the electrical connectors off especially the drivers side closest to the fire wall. I used vice grips to wiggle and pull them off. A screwdriver twisted counter clockwise on the bottom of some worked effortlessly others not so much kind of chewed them up a little. Overall though helpful video.
I have a C350 and I have been putting off this job because it seemed too tedious to remove the manifold. This video showed that it's not as bad off a job that I thought, I'm going to tackle it asap. Thank you very much for this helpful guide!
Not bad at all! Just make sure you grab some new intake manifold gaskets to slap on while you're in there, as any damage to the seals on removal can cause some strange running characteristics afterwards if you reuse them. We have everything you'd need to get it done in our "M276 Ignition Service Kit" on our site!
Great video! Especially replacing the green (and expensive) plenum seals @ 14:05 - my Mercedes dealer re-used the old ones and car broke down 10 mins after collecting it from a £400 service as they re-used the old seals and they leaked!!!. One of the reasons I now self-service my cars. By the way, you don't have to remove the plenum to change the spark plugs: its possible to unbolt the air filter housing and gently swing it out the way as the flex coupling near the MAF can bend - this exposes the coils/plugs. Also, spark plug no 6 (near oil level tube) is a pain to access. Greetings from the UK.
I did it without taking the manifold off, it was kind of a pain and the ass to get my big ass hands through there, but I did it :). Thank you anyway, wonderful video!
Also, before removing plugs, take a blow nozzle and clear any and all debris from around spark plug to save anything from falling into cylinders. Put dielectric grease in boot at plug to ease removal next service, unless you are going to replace boot every time you remove them.
Great video - I love your kind patient way! I tried this in this past few days and have had real problems; 1) removing connectors on top of coils...yes, I pulled the tab out but these are not veery user friendly connectors! 2) pulling the coils off the plugs. I was only able to get #1 off and of course cracked the plastic. I tried getting #2 off the plug but the Lisle tool wouldn't fit. So it would not come off no matter how hard I tried. I wish you were here!!!! LOL! Oh - It's 2017 GLE350 and the access to the 2 bolts at the rear of the intake manifold is extremely poor so I was doing all this was the manifold on the car.
if you use a small 90 degrees pick, you can insert the pick into the opposite end of the connector and use the tip of the pick and lift the tab inside as you push the connector out. I had your issue until I saw a video w the tech inserting the pick and it came out very easily. Diry traps into that connector female casing and makes the male connect too stiff to disconnect. watch this removal part at 3:06 time slot, you can see how he picks the connector tab czcams.com/video/mAk_QSfFRmI/video.html also here is another great video on removal of the manifold, very easy czcams.com/video/j5HZijBqBG0/video.html
This video is as good as it gets! Great job, Michael! I have done this job three times and #4 will be this morning. This video will speed the job! Thank you. I did purchase the complete Bosch ignition kit from FCP Euro.
I want to Thank you for the amazing detail step-by-step tutorial on Sparl Plugs and Ignition Coil for the M276 engine. I just did my very first E350 Convertible. This was so helpful in doing it right. love FCPEuro. Long time client and yall keep making it easy to do it yourself. Really appreciate how to approach engine work. Also will be replacing my camshaft magnets and sensors along with the sacrificial wires. Yall need to include the bolts on all your kits. It makes a big difference if you end up having problems with bad bolts or lose them. LOL Thanks
Outstanding video and just what I was looking for. I need to R&R the intake camshaft position sensor on the driver's side bank of cylinders and the plenum just covers it. I was stumped as to where the bolts were until I found this video. Even includes the tools needed.
Great video! More steps, but way easier job than trying to sneak everything out and back in with the manifold on for most people without damaging parts. Plus, you gotta have just the right tools for those tight spaces. And smaller hands would probably be easier if I had those. Only thing I did different was unplug/remove the ecu completely. Easy to do, more space and I think there's lower chance of potential damage.
It was mentioned in another video (w/o removing intake) that disconnecting ECM will cause loss of memory and create a multitude of problems. Don't do it!
Mike, thank you a thousands times. This was exactly what I needed. On the drivers side I ended up hooking a small nylon rope under the plastic tag to pull the coils, so easy. Damn Germans and their tiny hands! Thanks again.
I would love to see a timing chain cover gasket replacement on the w212 m276 e350. Its very common to have leakage and every m276 I have seen has the residue and small leaking on the timing chain covers on both sides. Can you do one of those?
This is an excellent how to video for this job. It shows all the bolts, the connectors, the vacuum lines, etc. Very well done. That said, please add disconnecting the battery cables before you begin. I noticed the battery cover was still on when you started the procedure. Does that ECU have power going to it with the battery cables connected?
I've found that the driver's side is the toughest and the ECU removal is a must. Removing the ECU is easy, but you must be careful with the wiring and connectors. Is there a reason why you didn't remove it? I was using CC on the video to not disturb others around me, and that option sometimes misses words. I've always removed the Neg battery connector and set it where it won't make contact with any metal. The plug closest to the firewall on the driver's side is the absolute worst one to get access, and I've scraped a few fingers on that one. I don't have an electric impact wrench for removing nuts and bolts, but that seems to be a great little device to have. When I do the next tune-up on our W204 M276 engine in the Spring, I will definitely use this video as a guide. Great video!!!!! Great advice!!
So much to break in there. Looks like more of a professional job. I will triple check the dealerships work to make sure the tech puts everything back exactly the way it was... My MB dealership techs like to shortcut putting clips back, and breaking clips and not bothering to replace them. Pisses me off when they do that.
If the coil clips don't come off easily, use a screw driver on the opposite side of the clip (without grey tab) to wedge the black plastic tab up and over the locking piece. Also if the coils haven't been changed in a while they may stuck on pretty tight, I used a small piece of rope wrapped around the "lip" to get a little extra leverage and lightly pulled with both hands and it came right off w/out damage. But be careful.
You are the G.O.A.T.! Any suggestions on what to do if the connectors that go on the ignition coil are stuck? I've got like four that won't come off lol
You are!!! Oftentimes, trying to push them in before pulling them out helps. An extreme maybe is trying to use a small pick to get the connector started.
Thanks for posting - gave me the confidence to do the job myself. I would love to know what all the electrical connectors and vacuum lines along the way are for.
Would be cool to see more on the m271 cgi engine from the w204!! Awesome guys thank you the info and great parts. With my m271 I have trouble keeping carbon away. I replace PCV system and parts. Wish there was a guide. Everyone should know to service the pcv system.
You mean the steel ring clamp? I did it using fat nose pliers. Push the clamp together using fingers, apply pliers and pull down toward you. Be gentle, it will snap in place. Saves you getting another custom tool.
After further review, while this video is still good for those that want to replace the intake gaskets, there is no need to remove the intake to replace plugs and coils. Passenger side access is gained by removing the air cleaner assembly only. The snap clamp must be removed, but it is no big deal. Drivers side access is gained by removing the ECU only. Happy DIY-ing.
Thanks for the video. Any video disassembly of the crankcase ventilation valve or the oil separator valve? I know it's a very difficult job to accomplish. Thanks.
it looks like theres a 2nd air filter in the filter housing on the engine side, is my w204 supposed to have that? also thanks for doing some M276 diy's.
Great video thanks man… however when you remove the manifold, the vacuum line that’s held by the t25 bolt in the back…. Do you have a part number for that bolt??
I want to add to this, the plugs should be Genuine Mercedes because this engine is direct injected, and the factory plugs guarantee proper indexing. To further ensure the electrode is indexed properly, the plugs must also be correctly torqued to specification. MB StarTuned makes it very clear that improper indexing can lead to performance issues and potential engine damage.
Few questions: 1. Is it completely necessary to remove the Intake Manifold to be able to remove the coils? 2. If you only have one bad coil, why go through the expense of replacing all the coils? Don't coils unusually work until they fail? Meaning that there is no in between. Old or new coils can fail at any time.
Great info ! Quick question, i am having a valve cover leak,[2016 E350] seems like removing the intake and coils is the only thing that i need to do to remove the valve covers to apply the new sealer , any tips or anything else that need to be moved out of the way to remove the valve covers that you know of?
I just replaced the coil for #3 cylinder. I tripple checked, when putting on the spark plug boot from the coil, it did NOT click, like old school spark plug wires did. Is that normal, no click? It just sits on top of the spark plug? It runs and drives perfectly, just surprised there’s no positive engagement.
sure same engine but on W166 (ML) ain't that easy... you can do it without taking out plenum but it will be tight on bank 6 or if you want more room than it's more labor intensive... cause you have to remove, windshield bottom cover, wiper motor to gain access to back screw of intake plenum...
Can you please tell me what kind of flexible tool extension to take off the Bolt on Manifold at the back on 2015 ML350 since we do not have enough space to get to it. Thank you.
If you run them past their required service interval, you can start to introduce poor performance and efficiency into your ignition system, causing for bigger problems down the line. We would advise replacing them at the recommended interval.
You need to go back and edit this.....add the correct description of the spark plug tool. It needs to be the 12pt "Thin" variant and long.....they to make several types....the plug hole is very narrow.
hello I need your help with the location of the camshaft bank 1 sensor sensor 1 my mercedes is a r 350 2012 what is the location of bank 1 the one on the right or the left thank you very much for your help

I've found that the driver's side is the toughest and the ECU removal is a must. Removing the ECU is easy, but you must be careful with the wiring and connectors. Is there a reason why you didn't remove it? I was using CC on the video to not disturb others around me, and that option sometimes misses words. I've always removed the Neg battery connector and set it where it won't make contact with any metal.
The plug closest to the firewall on the driver's side is the absolute worst one to get access, and I've scraped a few fingers on that one.
I don't have an electric impact wrench for removing nuts and bolts, but that seems to be a great little device to have.
When I do the next tune-up on our W204 M276 engine in the Spring, I will definitely use this video as a guide. Great video!!!!! Great advice!!
Great video!
So much to break in there. Looks like more of a professional job.
I will triple check the dealerships work to make sure the tech puts everything back exactly the way it was... My MB dealership techs like to shortcut putting clips back, and breaking clips and not bothering to replace them. Pisses me off when they do that.
This video is giving me confidence to do my 2015 c350 4matic with the same engine great video my guy!
You can do it!
Thanks!! Gonna try doing it tomorrow my only worry is the ecu computer!
Do you have to disconnect the battery when you do?
Very professional job well done answer all my questions l had in mind thank you for your time spent doing this video, God bless you
Great video - really appreciate tool numbers. Very clear, good pacing - thanks!
Great video! I just picked up a 2019 GLS 450 with the M276 engine. This will be very helpful.
Enjoy your new ride, Pat!
If the coil clips don't come off easily, use a screw driver on the opposite side of the clip (without grey tab) to wedge the black plastic tab up and over the locking piece. Also if the coils haven't been changed in a while they may stuck on pretty tight, I used a small piece of rope wrapped around the "lip" to get a little extra leverage and lightly pulled with both hands and it came right off w/out damage. But be careful.
You are the G.O.A.T.! Any suggestions on what to do if the connectors that go on the ignition coil are stuck? I've got like four that won't come off lol
You are!!! Oftentimes, trying to push them in before pulling them out helps. An extreme maybe is trying to use a small pick to get the connector started.
Thanks for posting - gave me the confidence to do the job myself. I would love to know what all the electrical connectors and vacuum lines along the way are for.
My Good People....Love it...
Would be cool to see more on the m271 cgi engine from the w204!! Awesome guys thank you the info and great parts. With my m271 I have trouble keeping carbon away. I replace PCV system and parts. Wish there was a guide. Everyone should know to service the pcv system.
More to come!
Bro thank you for making this video
Those are NOT single-use clamps at the connection of throttle body and airbox. You just need the correct tool to put them back on.
You mean the steel ring clamp?
I did it using fat nose pliers. Push the clamp together using fingers, apply pliers and pull down toward you. Be gentle, it will snap in place. Saves you getting another custom tool.
After further review, while this video is still good for those that want to replace the intake gaskets, there is no need to remove the intake to replace plugs and coils. Passenger side access is gained by removing the air cleaner assembly only. The snap clamp must be removed, but it is no big deal. Drivers side access is gained by removing the ECU only. Happy DIY-ing.
Sorry you misspoke, The ECU is on the Drivers side in the USA.
@@frederickyahnsr.9004 Thanks. I edited it to drivers side.
Can we get a video for replacing valve cover gaskets on M276
thanks for this my friend, EXCELLENT video and helped me tremendously.
Glad it helped!
This is a great video. It also convinced me NOT to buy the C43 AMG that I test drove this afternoon.
Excellent video!!!
Thank you for watching!
Do these plugs needed to be indexed and how do you ensure it is done properly? Thanks!
The ML has to have the bulkhead removed to get to the two rear manifold bolts. It can be done.
czcams.com/video/E6DIdg8IBA0/video.htmlsi=HmBHHcSpuezlkoJ2
😎👍
Can you guys also use this opportunity to clean the carbon off the intake valves? Since the manifold is already off
That is certainly something we can visit!
Same. Would love to know if that's even possible. You've earned a new subscriber.
Same for GLK350 2013-2015
Thanks, Ar!
Thanks for the video. Any video disassembly of the crankcase ventilation valve or the oil separator valve? I know it's a very difficult job to accomplish. Thanks.
Thank you 🙏 much appreciated
it looks like theres a 2nd air filter in the filter housing on the engine side, is my w204 supposed to have that? also thanks for doing some M276 diy's.
Great video thanks man… however when you remove the manifold, the vacuum line that’s held by the t25 bolt in the back…. Do you have a part number for that bolt??
Clean step by step, thanks!
But do I need to disconnect the battery?
Thank you for watching! Not mandatory for this job, but certainly not a bad idea to do so as a safety precaution!
I want to add to this, the plugs should be Genuine Mercedes because this engine is direct injected, and the factory plugs guarantee proper indexing. To further ensure the electrode is indexed properly, the plugs must also be correctly torqued to specification. MB StarTuned makes it very clear that improper indexing can lead to performance issues and potential engine damage.
can someone point out where the camshaft sensors are in this video? I'm trying to replace mine but can't locate which one in Bank 2 (Driver side).
Hi Fcp Euro you guys need a video of setting the timing of the cam shafts and or installing check valves and rattle kit for timing chain
We can certainly add it to our queue!
Thank you kindly alot of your customers are asking about this procedure like myself.
Thank you for the great video! Do you need to lubricate spark plugs?
Copper anti-seize ftw
Can you do a video of the modern M256 engine spark plug change? GLE 450?
Is the spark plug remover tool proprietary from MB or can any swivel removal tool work?
Few questions:
1. Is it completely necessary to remove the Intake Manifold to be able to remove the coils?
2. If you only have one bad coil, why go through the expense of replacing all the coils? Don't coils unusually work until they fail? Meaning that there is no in between. Old or new coils can fail at any time.
This video makes me want to save the $570 the dealer wants to do it!
Hello,
Any recommendations on how to remove stuck coils I all of them are really hard to remove compare on how easy it was on your video any tips?
thanks for the video,very informative,did you index the plugs when installing them?
Great info ! Quick question, i am having a valve cover leak,[2016 E350] seems like removing the intake and coils is the only thing that i need to do to remove the valve covers to apply the new sealer ,
any tips or anything else that need to be moved out of the way to remove the valve covers that you know of?
Great video. I just followed to replace mine. I found a lot oil on intake manifold. What part failed and should be replaced?
the PCV at the rear, pass. side
@@glasser2819 Thanks!
Can show us how to remove crank pulley
Looking for the part number for the circular coil connector. I had a latch break on one when removing. Cant find any information onthis part.
I just replaced the coil for #3 cylinder. I tripple checked, when putting on the spark plug boot from the coil, it did NOT click, like old school spark plug wires did. Is that normal, no click? It just sits on top of the spark plug? It runs and drives perfectly, just surprised there’s no positive engagement.
sure same engine but on W166 (ML) ain't that easy... you can do it without taking out plenum but it will be tight on bank 6 or if you want more room than it's more labor intensive... cause you have to remove, windshield bottom cover, wiper motor to gain access to back screw of intake plenum...
Thank you for the notes on that model, Peter!
At what mileage is this service being done?
2012 E350 owner.
Owner's manual says to do the plugs at 60k Miles.
Hi Alberto, 60k intervals are correct! Mike mentions the vehicle behind him had just over 100k miles, so it was past due.
All of the m276 content is for the non turbocharged version. Please try to put some content on the twin turbo m276
We can certainly work on that!
Don't the plugs need to be indexed as per your website instructions ?
Can you please tell me what kind of flexible tool extension to take off the Bolt on Manifold at the back on 2015 ML350 since we do not have enough space to get to it. Thank you.
Where are the old gaskets that the new gaskets are replacing? I missed the old gaskets being removed.
Old gaskets sometimes stay on the intake manifold so you literally have to turn the manifold upside down and remove the old gaskets.
As @@joseherrarte948 mentioned they will usually stick to the underside of the intake manifold, you can simply pull them right off and toss em.
Mercedes claims that your supposed to get your spark plugs changed every 60K can i run them longer?
If you run them past their required service interval, you can start to introduce poor performance and efficiency into your ignition system, causing for bigger problems down the line. We would advise replacing them at the recommended interval.
Why did you remove the plenum? You don't have to.
You need to go back and edit this.....add the correct description of the spark plug tool. It needs to be the 12pt "Thin" variant and long.....they to make several types....the plug hole is very narrow.
hello I need your help with the location of the camshaft bank 1 sensor sensor 1 my mercedes is a r 350 2012 what is the location of bank 1 the one on the right or the left thank you very much for your help
How is this possible on a 2017 GLE. The rear E10 bolts on the manifold are blocked by the firewall, literally impossible to get a tool in there.
I'm going to give it a try. I'm a bit nervous but it's worth a try.
Just take your time, and everything will go smoothly!
The manifold does not come off this easy on the ML. Rear two bolts are impossible remove with the windshield wiper assembly in place.
