1.8T N75 Valve – Boost Pressure Control Valve – VW Audi – 058906283C
This 1.8T N75 valve is located on the top of the engine within the boost pressure control lines. This valve N75 valve is present on most 150, 180 and 225 bhp Volkswagen Audi Group models.
The N75 valve particularly for the 1.8T is well known to fail resulting in incorrect boost delivery caused by the wastegate actuator opening incorrectly. This is particularly noticeable at higher RPMs as boost is requested by the vacuum signal.
These valves are not to be used on any re-mapped engines running anything over standard manufacturers limits. Any items doing so will invalidate an warranty given on this part.
