CPS issue- 2003 W220 500L- FRUSTRATED
Hi all, Hoping someone may know something to help. Car showing signs of CPS failure so had this replaced. No change so checked it again and had replaced again. Car seems slightly worse, revs dip while braking towards traffic lights like car is stalling and the cranking takes as long. Dealer...- davidbownes
