WARNING: This page is about a different car, the 1994 Volkswagen Passat and 1994 Volkswagen Corrado. However, it is still accessible from the selected car via links, so may be relevant.
If no faults were found while performing preliminary inspection procedures, proceed with self-diagnostics. If no fault codes or only pass codes are present after entering self-diagnostics, proceed to TESTS W/O CODES article in the ENGINE PERFORMANCE for diagnosis by symptom (i.e., ROUGH IDLE, NO START, etc.).
