.
- After repairing the malfunctions, check DTC memory again to erase
any malfunctions that may have been stored (e.g. by disconnecting
connectors).
- Stop engine (switch ignition off) and start again.
- Test drive for at least 10 minutes.
- Carry out Automatic Test Sequence by inserting address word 00.

Diagnostic Trouble Code (DTC) overview

Notes:

The Diagnostic Trouble Code (DTC) overview is organized according to SAE and VAG trouble codes.
Diagnostic Trouble Codes (DTC) for which the MIL is not switched on by the engine control module after a malfunction is
recognized are identified with the MIL switching condition "off."
Diagnostic Trouble Codes (DTC) for which the MIL is switched on by the engine control module immediately after a
malfunction is recognized are identified with the MIL switching condition "immediately."
Diagnostic Trouble Codes (DTC) for which the MIL is not switched on until the malfunction is recognized after taking 2
trips (FTP 72) are identified with the MIL switching condition "2 Trips."
Always repair the malfunctions with the MIL switching condition "immediately" first, and then the malfunctions with the
switching condition "2 Trips."
