This is a campaign issue. Not sure there covering this anymore. Oil is pumped up thru cables to the coils. This is the oil sensing module. If this is not covered anymore this may set you back 10k -15k
Rough idle sluggish loss of power check engine light on. Replaced coil packs and injector seals. Did not fix problem.
car mis fire and lose power took to dealer and they said 6,7,plug is bad so they said the whole coil rack has to be replace very expensive job I am very up set this car is a headache but i love this car very powerful etc.
CL65 went into limp mode. Original diagnosis by MBZ dealer was ICM - and it was replaced. Car went into limp mode the next day and left coil bank and plugs were replaced at 49800. 700 miles later, the right coil bank went out. Seems improbable that both would go out without some other upstream problem.
I have had this issue happen to me 2 times now. The first time the mercedes dealership did a "good faith repair", this second time just happend not even a year later. This is not a cheap fix and I am extremely upset that this is a recurring problem. There must be some other underlying issue wrong with this thing.
coil rack is bad took my car to american service center , for B service and a problem with my trunk not closing when pushing the red buttons on trunk they fix it costing me 2000.00 then i pick my car up drove for 2 days and my car started to misfire and lose power etc.
