This week in the workshop we had a VW Golf 1.6 tdi common rail in. Customer reporting the check engine light is on. A diagnostic check s carried out and found fault code P0403 EGR valve Exhaust Gas Recirculation Circuit Malfunction.

We replaced the EGR valve along with all associated gaskets and seals. once complete we carried out a thorough road test and carried out a further diagnostic check to ensure that the fault has been rectified.
