W205 engine noise
Hey guys so is this engine sound normal? I hear a knocking noise behind the lifter noise. The car runs perfectly and only has 36,000 klms. Any help would be appreciated.

Difficult to say but I once had a car that sounded like this after the head gasket had gone. If you open the radiator cap (NOTE - ONLY DO THIS WHEN THE ENGINE IS COLD) does the water 'rush back in' or is there any creamy white type substance on the rad cap ?

So I managed to locate where the sound is coming from. It’s coming from this part here at the back of the engine. Does anyone know what this part is called?

Sorry to hear your bad experience. Are you expecting a 9 year old car to still be under warranty?
