I have a 2000 C230 Kompressor Sport. The car is fine when the engine is
cold, however once warmed up, the kompressor tends not to work.
I took the car to my dealer and they found a fault on the crankshaft sensor,
which they have now cleaned. No improvement, in fact I think its worse.
The dealer now wants the car for an incredible 2 days of fault
finding...which could be very costly.... Does anyone have any experience /
advise they can share on this please?
