How to replace the coil and spark plug on a Mercedes Benz ML350 3 5L gas engine

This 2015 Mercedes Benz ML350 had a rough running engine and the problem was intermittent. I pulled two trouble codes from the ECM, which were P0352 and P0302. P0352 refers to a ignition coil problem or its related circuitry on cylinder number two, and P0302 refers to a misfire on cylinder number two. In this video I replace both the coil and spark plug on cylinder number two. Off camera I replaced all the spark plugs on this engine, which is why there is a dramatic light change between clips near the end.

Tell us what socket sizes you are using to complete the repairs.

What spark plugs did you order??

[@nasty954]

I gave it a thumbs down cause you showed the easy side

[@mrjesus61]

why you don’t change all the spark plugs on the same time?

[@brandonmanning5821]

Cause he can't get to the back ones 🤣🤣 he knows it's hard

[@everythingtrucking8949]

Where did you get the coil pack from?

[@smallengineshop]

A local auto parts store

[@eduardpalmer2601]

Nope. why would i vote for anyone that openly says she would gut social security and medicare?

[@alnichols5282]

Thanks for the video, I’m about to try mine since the shop wants $1600 to do it. Much appreciated!!!!

[@smallengineshop]

Glad I could help

What if I’ve got to get to the other side and how do you know which one is which? Are all odd numbers on one side? 🤷🏻‍♂️

[@smallengineshop]

If I remember right the passenger side is bank 1 and numbered 1 through 3 starting from the front. Bank 2 is 4 through 6. This is a USA Mercedes, so the drivers side is on the left. You can verify by doing an online search.

No need to torque for correct indexing?

[@BarGolum]

[@BarGolum]

@@smallengineshop hi I think I didn’t watch the video from the beginning tie fisrt time now I watched it again I noticed that you said coil #2 like 5 times lol, thx for the video, encourage me to change my coils and spark plugs soon.

[@kalk3008]

Which plugs and coils did you order?

[@smallengineshop]

I don't remember, but I do remember there were several different brands to choose from.

[@everythingtrucking8949]

I got a coil pack from O'Reilly's.. Light never went off? Still sputters

[@williamalbright8878]

Very nice work, thank god wasn’t the back one

[@MrGoToGuy2011]

THANK YOU!!!! When you replaced the drivers side coils/plugs did you have any difficulty because of space?

[@7150285]

Discount the take out the whole ECU for bank 2 driver side. It is much much more challenging...

[@smallengineshop]

Ya, the drivers side is the hardest.

[@seanli682]

[@prandomable]
