Erasing Fault Memory Using VAG 1551 Diagnostic Tester

1. Ensure that fault memory is recalled until blink code 0000 appears, ignition switch is turned Off and faults have been eliminated, and vehicle has been test driven and a speed of at least 20 mph has be achieved. VAG 1551 diagnostic tester or any of its adaptor harnesses must not be connected during test drive.
2. Read fault memory as previously described, after blink code 0000 has been displayed, fault memory is erased.
3. Repeat self-diagnosis after erasing fault memory, diagnosis is complete only after fault code 4444 has been displayed.
