Genuine Volkswagen Audi - Upgraded Piston Diverter Valve, Electronic ES#259456

One of the weakest spot on any chipped 2.0T cars is the diverter valve. The factory diaphragm can crack under high boost pressure, and create a massive boost leak. This OEM valve from the new FSI motors features an upgraded piston type design, modeled after the more expensive aftermarket units. This is the perfect solution for anybody needing an upgraded DV, that doesnt want to void their warranty with "aftermarket" parts

 

Later model year DVs are stronger than the earlier ones (not sure exactly when the switch happened) so you might not need it at all.

 

revision H is the current one or G. holding up strong.
