Took our R350 in for CEL service only to find out we have the 1200 and 1208 codes (balance shaft issue).

I'd like to say MBUSA is stepping up to the plate, but after we passed our 100K mile extended warranty on our R350, they said they would not help. Our car was a CPO bought in 07 with 16k miles. Some service by the dealer, but most done by a closer to home indy (which MBSUA mentioned) and two oil changes by myself.

So now we have a $9,000 repair bill to fix the known issue of the balance shaft and replace the intake manifold.

MBUSA sucks.
