2012 Volkswagen Passat 1.6 TDI – Engine judder at idle.
FAULT:
A 2012 Volkswagen Passat 1.6 TDI is in our workshop and has an engine judder at idle when the air conditioning is operating. We have carried out some basic checks on the air and fuel systems and checked for any stored trouble codes, none were present. Can you help?
FIX:
Yes, we are aware of this fault affecting 1.6 TDI Passat models with CAYC engine code. The cause is due to a faulty fuel pressure regulator control solenoid. Fit a new fuel pressure regulator control solenoid, located on the fuel rail (Fig. 1.1). Carry out a road test to ensure the engine judder has been eliminated..
