belt noise on the engine, what do you think?
The car is 3 years old and 39k m. There is a "belt noise", but what do you think I should change? only the polyV belt, or the tensor pulley too -the car has only 39k m, and the tensor pulley costs more than 100 €...-.
I don't understand how such a new merc can do this things...
