 The following table lists all malfunctions, with the corresponding 5 digit code 

numbers, that can be recognized by the radio 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. 

 DTC table may also include a description of the type of malfunction.  

 Before replacing components, check the wiring and connections to these 

components as well as ground connections, according to wiring diagram.  

 When a repair has been carried out, the Diagnostic Trouble Code (DTC) memory 

must always be erased and checked again with the VAG 1551 Scan Tool (ST). 

 If there is a specific complaint and no malfunctions are recognized after checking the 

Diagnostic Trouble Code (DTC) memory, carry out function 03, "Output Diagnostic
