Really just looking for some assistance or pointers, posted in e60 section but haven’t received any help due to a lack of n62 owners I suppose so I’ll try my luck here.
2007 550i (yes I know not a 6 series)
The car continuously pops 2A8C and 2A8D will only sometimes throw the exhaust cam crank tooth offset error sometimes only on bank 2 sometimes on both banks. I have swapped vanos solenoids and also replaced them I have also swapped and replaced cam sensors still no luck car will start and idle decently for maybe 10 seconds then just falls on it’s face. Does not accept throttle for the most part and on the rare occasion that it does it will backfire through the intake sometimes cylinders will also knock sometimes when it runs extremely rough. The cat on passenger side has gotten red hot a few times (LHD car) I bought the timing tool set and checked that out but it is 100% in time on both banks. So at this rate I’m stumped. Any help is highly appreciated at this point. Car has 167k miles on it. I’ve ordered a new vacuum pump as well old one is leaking.
Could this potentially be a fried DME?
