Genuine OEM Pierburg boost pressure valve for the turbo for ALH engine code. Also known as N75 valve, or wastegate solenoid. Fits 1998 and 1999 New Beetles and 99.5 Jetta/Golf TDIs ONLY. This valve will fit those cars, which have a different plug than the later Mk4 TDIs.
When failed, this device will cause the turbo to appear to be completely dead. Often, cars diagnosed as a failed turbo simply need a new N75 valve.
