S320 cdi rpm not going above 3000
Having s320 cdi 2003. Its not going above 3000 rpm, engine check light comes after driving several miles....
I've opened the MAP sensor, there was some oil on it which I've also cleaned..... changed the MAF (mass air flow) sensor but the car is still the same....Also went to the dealer, he says that this happens because of the weak engine of the car which spills oil on the MAP sensor through its manifold..... But i think cars engine is fine....
