VW and Audi Diverter Valve Failure

A common failure on Audi and Volkswagen turbo cars are the diverter valves, repeated movement of the diaphragm leads to tears or complete perishing of the rubber diaphragm.

Some of the vechiles with diverter valves are;


VW Golf MK5 GT

VW Passat 1.8T

VW Passat 2.0T

Audi B5 A4 1.8t

Audi B6 1.8T

and many more.


We often upgrade the diverter valves to Forge Motorsport items which are superior to the factory items.
