DTCs 00597 - 01424, DTCs 01425 - 65535

Notes for DTC table
^ The "Automatic test sequence" must always be initiated via the button combination -0- -0- at the beginning of every troubleshooting procedure, because the various control modules are inter-connected via a data-BUS wire. This checks all of the control modules installed in the vehicle for any Diagnostic Trouble Codes (DTCs) they may have stored.
^ The list contains all malfunctions that can be recognized by the ABS control module (w/EDL) -J104- and printed out by the VAG1551 scan tool or displayed on the VAS5051. The malfunctions are listed in order according to their 5-digit DTC numbers.
^ The DTC appears (in operating mode "Rapid Data Transfer") only on the print-out.

Example:
DTC P-Code Malfunction type number
5-digit 5-digit 3-digit
18256 P1848 035

^ The 5-digit P-code which sometimes appears next to the DTC is intended for On Board Diagnostic (OBD) II and can be ignored.
^ The three digit malfunction type number is a data code and can be ignored. The text relating to malfunction type is, however, useful.
^ Before replacing the component determined to be malfunctioning, check all relevant harness connectors, wires and Ground (GND) connections according to wiring diagram.
^ After repairs, DTC memory must always be checked again using the VAG1551 scan tool or VAS5051 tester and erased.
^ Road test vehicle (at above 60 km/h for 30 seconds).
^ Check DTC memory again Offer road test.
