High Pressure Fuel Pump Noise
Hi there,
As I got my CLS550 for two weeks now, this is my first post in this forum!
Before i bought the car from my dad we went to the dealership to do a full service and so on. Already there I suggested them to check the annoying knocking noise which comes from the engine compartment. Well so they checked it, and said it's a common M278 problem - nothing bad about it.
Well that noise - my dad was not disturbed by it - but I still got good ears and I want that fixed - it sounds as something is broken and you here it from a good distance.
Then i noticed that the High Pressure Fuel Pump is driven by the crankshaft using a camshaft roller - is this true?
Can this roller be replaced in order to avoid the terrible noise?
Part number or even exploded drawing existing?
You would really help me out!
Thank you
