What It Is
A Pierburg N75 valve, the turbo boost pressure converter used on Mk4 ALH TDI and B5.5 BHW Passat engines.
Connector Compatibility Note
1998-99 New Beetle and 99.5 Jetta/Golf TDIs use a square connector plug rather than the standard connector this valve ships with. Rather than paying for the significantly more expensive N75 variant built specifically for that square plug, KermaTDI offers an adapter that connects on the body side and makes this standard valve compatible with those earlier cars. The adapter is sold separately from this listing.

Common Questions
Do I need anything extra if I have a 1998-99 New Beetle or 99.5 Jetta/Golf?
Yes. Those years use a square connector plug, so you'll also need the separate connector adapter to make this valve work with your car's wiring.
Does this fit my 2004 Passat?
Yes, this valve covers the 2004-2005 B5.5 Passat with the BHW engine, in addition to the Mk4 ALH platform.
What does this valve actually do?
It's the turbo boost pressure converter, which regulates how the turbo's wastegate or vane actuator responds to vacuum signals from the ECU.
Is the connector adapter included with this valve?
No, it's sold separately, since only certain early model years need it.
