M111.960 Engine Noise
I have a W124 E220C and the car is very silent besides the engine. There is little wind noise, there is very little tire noise, but the engine is pretty noisy. Even on the highway the only noise heard is the engine more or less.
Is this normal? Is it just a very noisy engine? Or do I have something wrong?
When idling it sounds fine. When free revving as well. There is no tapping, knocking etc.
I suspect there is a exhaust hole, but it is barely audible at idle so I am not sure if it's a hole or not.
