Cylinder knock!?
I have E63s 2014 with low 36000 km. The car was running flawless till 2 days back. Has a sudden engine hesitation and check engine light. Pulled over. Turn off the car then on ... flawless but today I had the same issue and did the restart and its gone. Took it to the dealer to read the logs, they told me it is a knockout cylinder 4,5 and 6 which could be highly caused by bad fuel type. They have added fuel injection cleaner to my full tank and asked me to floor it few times on highways to get rid of the extra carbon that could be also the reason. I think it is a weird assumption. They asked me to bring it back in case the same will happen to do a light and compression test.
any previous experience with that?
PS the car running on stage 1 renntech map, catback and filters.

2014 E63S; AMS 100 octane ecu tune; edok tcu tune; BB intakes; dyno tuned
Coil packs or plugs? How many miles has it been tuned
my bet is that it needs new plugs
