Dears,

Recently I had a problem with the right bank coil misfiring. Coil pack right bank 2751500680. I replaced with a used one which I bought from eBay from a trusted seller. The car works but better than before. I have checked with c4 star. Still I have an issue with what is shown in the picture attached. Please help me solve this issue. Thanks

Good morning,

Okay, with all the misfires, did you change the plugs and at least change the boots on the coils?

I am not a fan of using used parts at all. Hopefully the coil pack is good.

As far as all the misfires, I would check the fuel pressure as well. Low fuel pressure will cause misfires due to the lack of fuel to the injectors.

Hello Roy,

acknowledged your email, however the plugs are new and the boots also new.

This is a temporary coils till I order a new set of coils from Mercedes, please let me know if a china set of new coils are okay.

I think am going to get the injectors cleaned and will check the fuel pressure as well hence the coil is good for now, will let you know the progress. Thanks

I would use the OEM. Aftermarkets with Mercedes is never a good idea.

Yes, have them professionally done. There is no additive made that has any effect on cleaning by adding to existing fuel.
