How to replace spark plugs on the AMG M156 - E63, C63, CLS63, S63 

I have not. 2 methods to do it on an M156, standard way where you thread the tester to spark plug holes (make sure you disconnect fuel rails..etc.) and the second method is an electronic compression test using Xentry. It works really well, but you need that tool and its expensive! What issues are you having?

For info, a friend of mine did it on a M156 2009 and the compressions were 13 bars on almost all cylinders, one at 12,5 and one at 14.

Good question, cause I have one too, 09.

Thanks

@@eyadm147 thanks, I have s63. I was going to ask about the ECU have you ever removed it?

I have not removed it. I know its in the fender well (passenger side). Should be fairly easy to remove once you take off the wheel and inner liner

@@eyadm147 oh okay, I believe mine is on the driver's side up top

Yes a lot of benefits especially spark plug ignition coils also injectors are very important to this engines
