Diagnostic Trouble Code (DTC) table

NOTE:

The following table lists all malfunctions, with the corresponding 5 digit code numbers, that can be recognized by the Data Bus On Board Diagnostic Interface -J533- and printed out by the VAG 1551 Scan Tool (ST).
If malfunctions do not occur regularly, these are displayed as occurring sporadically ("SP").
DTC codes appear only on print-out.
Before replacing components, check the wiring and connections to these components as well as ground connections, according to wiring diagram.
When repair has been carried out, the Diagnostic Trouble Code (DTC) memory must always be erased and checked again with VAG 1551 Scan Tool (ST).
If there is a specific complaint and no malfunctions are recognized after checking Diagnostic Trouble Code (DTC) memory, carry out "Read measuring value block". Refer to Read Measuring Value Block (function 08) .
