S65 Amg engine issues
Hi, I recently bought an 08 s65. The car now has no power and revs very slowly even when In neutral. There is also a strong smell of petrol from the exhausts. There is a misfire on 7-12 , I have attached a screenshot of the fault codes. There are also some other codes which I have listed. Any ideas of what’s wrong ?

First off, I'd remove the coil assembly followed by the spark plugs. Visually check their condition. If they're black and wet looking AND smell like fuel, you for sure are experiencing a rich misfire condition which is incomplete or no combustion.

Same symptoms on my 07 S65
Hi, I am having exactly the same symptoms with the same fault codes on my 2007 Mercedes S65. All of these came up from nothing (I’ve had the car for 3.000 km with no issues; I should probably mention that I have installed NGK Iridium spark plugs when I bought it. The old Mercedes ones were in terrible condition).
Have you been able to find the issue and fix it?
Thanks in advance

Coil packs... aka, “the best known reason not to buy a 65 car, pre-W222”... sorry... but at least it’s well documented... someone around here has a link to the coil pack rebuilder in the UK... good luck.
