►Replacing the spark plugs on a Mercedes-Benz M276 engine is a bit more involved than most other cars you come across. To access them, you have to completely remove the intake manifold and throttle body. Because of this, we recommend replacing your ignition coils while you have all of that disassembled.
This video covers a wide range of Mercedes cars and SUVs with the M276 engine, such as the W204 C300, W207 & W212 E350, GLE350, and ML350. Seeing as the intake manifold and throttle body have to be removed, our M276 spark plug kit linked below comes with all the necessary replacement gaskets.
Join us as Michael Hidalgo, FCP Euro’s resident DIY expert takes us through the step-by-step process of completing an ignition system service on this Mercedes-Benz E350.

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. Passenger side access is gained by removing the ECU only. Happy DIY-ing.
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?
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.
Can show us how to remove crank pulley
Can we get a video for replacing valve cover gaskets on M276
I had a number 2-cylinder coil failure. This coil is right under the air box and will work for 1 and 3 also. I did not remove the intake manifold just the air box and the one electrical connector. The first clamp was removed and reused. removed by prying just under the raised section with a screwdriver. To install the clamp, use a little soap or tire shine to lube up the rubber and a flat nosed plier to squeeze the clamp to snap in place. Removing the coil and installing the coil just like the video. Optional: I drilled a 1/2-inch hole in the fire wall just next to the last airbox screw so I could fit my 1/4-inch drive torx through to make getting the airbox cover out easy. This is something mercedes should have done and provided a removable plug. This will make any future air filter changes/coil changes a lot easier.
thanks for this my friend, EXCELLENT video and helped me tremendously.
Great video – really appreciate tool numbers. Very clear, good pacing – thanks!
Why did you remove the plenum? You don't have to.
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.
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!
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.
Amazing video, very professional, no BS, thank you
The manifold does not come off this easy on the ML. Rear two bolts are impossible remove with the windshield wiper assembly in place.
Could you lay the ECU over the center of engine and afford more access to plugs and coils, just curious.
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!
Hey I did all that but it still seems like it’s making the same thing
Same for GLK350 2013-2015
INTAKE NO NEED TO REMOVED.
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.
Thank you for the great video! Do you need to lubricate spark plugs?
This is a great video. It also convinced me NOT to buy the C43 AMG that I test drove this afternoon.
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.
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).
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!
At what mileage is this service being done?
2012 E350 owner.
Owner's manual says to do the plugs at 60k Miles.
