2006 Audi A4 Fuel Pressure Regulator Parts and Q&A
Q: How to replace the fuel pressure regulator on 2006 Audi A4?
A: This process applies only to June 2003 and earlier 3.0L V6 models, as the pressure regulator for other models is part of the fuel filter. Remove the engine cover, relieve fuel pressure, disconnect the vacuum hose, and remove the pressure regulator. Replace O-ring seals, lubricate new ones, and reinstall the regulator. Check for leaks before replacing the engine cover.
