Hi chaps, I’m new to MB. Having just chopped in my BMW 540 Msport in November 2020 for a 2012 W212 E63 5.5l bi turbo with 49k miles on the clock.
I was aware of the chain stretch issue surrounding these cars, but had some comfort knowing the car had the chain upgrade in October 2018.
Everything was great, enjoying the car every minute until the EML came on!
The car has been in the Mercedes dealership for the past week for a strip down as the car was throwing P0022 fault code.
Couldn’t be the timing chains surely, not after all the work previously done less than 10k ago.
Nope, it turns out that during the repair in October 2018. The fitter managed to block one of the oil galleries with sealant which appears to have affected the oil pressure into the head which caused the cams to wear away the aluminium head journals.
An oil check valve wasn’t installed either, so coupled with low oil pressure and oil drain down from the head has resulted in major damage.
Estimated cost of repair is £19k!
Cue lawsuit with dealer I bought it from, and desperate pleas to Mercedes Uk for gesture of good will.
Mercedes refused gesture of good will, but managed to negotiate cost down to £9k but getting the cylinder heads repaired instead of new (saving £3k alone).
Just goes to show, that despite all the known faults with these engines. There is always something that can go wrong, and when they do, they cost mega bucks to fix.
As much as I love the car, it’s fair to say ownership so far has been as enjoyable as a sandpaper covered dildo.
So after a top end rebuild, what more can go wrong with the car...?
I’ll keep you posted....
