Audi A4 Serpentine Belt Tensioner Failure (Solution)

Author: Michael II.

Serpentine belt tensioner broken, serpentine belt torn.

Up to chassis number 8DWA 237111.


Cause:
Lack of free play on the generator pulley can lead to overloading of the V-ribbed belt drive. As a result, the V-ribbed belt tensioner may break, and/or the V-ribbed belt may tear.

Solution:
Replace the serpentine belt tensioner and the serpentine belt.

It is essential to replace the fixed pulley on the generator with a freewheeling pulley. Freewheeling pulley for Bosch generator No. 028 903 119 T.

Friction wheel for Valeo alternator No. 028 903 119 AC.

Make sure to install spacer ring No. 028 903 237 A between the freewheel pulley and the generator, otherwise the belt will be damaged.
Please provide the German text you would like me to translate.
