Engine noise Mercedes Classe E 5 close to a friction
In the event that you notice a motor noise on your Mercedes Classe E 5, and, that this noise is close to a friction, it is likely that one of your belts or one of the parts that causes it is the origin of your problems.Often, we will start to notice a motor noise on Mercedes Classe E 5, close to a friction when one of the belts is worn out or when one of the related parts like your alternator, or your tensioner roller is the issue. So please remember to examine their state and go to your mechanic to replace the parts in question.

Finally, the second possibility is that your silent engine blocks or rubber mounts may be dead. This causes a metallic noise every time your engine moves, either because of a change of pace (acceleration or braking) or, when you pass on roads in poor state. Check the state of your silentblocks and replace them if needed.
