Diverter Valve VAG

We are still seeing plenty of diverter valve (DV) failures here at Gotboost.

The original factory diaphragm can crack under high boost pressure and create a massive boost leak. The new OEM valve 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 does not want to void their factory warranty with "aftermarket" parts
The DV is a pathway for boost when it is not being used by your engine. Whenever the throttle body is closed, such as during gear shifts or deceleration, the boost needs an escape route or the pressure will build up and slow down the compressor. This can cause turbo lag or even damage the turbo.
A Blow Off Valve (BOV) or dump valve performs the same task as a Diverter Valve, but instead of returning the boosted air back into the intake, it vents it to the atmosphere making a distinctive noise.
We can replace your DV with the uprated part for just £76.25.
