Volkswagen TDI Pressure converter for the EGR, also known as N18 valve, fits VW Jetta TDI, Golf TDI and New Beetle TDI on the A4 chassis with engine code ALH. See below for specific model years.

When failed, this device may cause an EGR fault code and fail emissions testing.

Importantly early 98 New Beetle/99.5 Jetta/Golf use a different style connector than is on this valve. Be sure to order the newer style connector below if your valve uses a square shaped connector. If you would like to purchase the old-style valve with the old-style connector rather than purchasing the new-style connector, the old-style N18 valve is available here.
