About Trouble Codes
DTC ChartsThese charts list all possible transmission faults which can be detected by the transmission control unit (J 217) and displayed on VAG 1551.
They include the DTC, Possible cause, and Component to check
If faults only occur intermittently, or if the fault memory was not cancelled when the fault was corrected, these faults are displayed as "intermittent faults".
If defective components are found, also check the wires to the components, according to current wiring diagrams.
Note to fault code 00526 - Brake Lamp Switch
^ The fault code is recorded after ignition is turned on and erased after the first time the brake pedal is depressed.
^ Before fault print-out, briefly depress brake pedal so that the previously recorded fault is erased.
Note to fault code 00532 - Voltage Supply
^ If fault code 00532 is displayed, no more faults can be stored. After separating the transmission control unit from the battery, the fault is always recorded. After ignition is turned on twice or Fault memory is erased, the fault in the Fault memory is erased.
