BOARD DIAGNOSTIC (OBD) 

GENERAL INFORMATION 

Radio system "Premium V" is installed from start of production. 

Radio system "Premium V - Monsoon" is installed as optional equipment from 10.00 production. 

Before troubleshooting or servicing, technicians must be familiar with the functions and operation specifics of 
the applicable standard or optional radio system. Always read the radio owner's manual and review all radio, 
tape player and CD changer functions. 

The radio is controlled by an internal microprocessor with On Board Diagnostic (OBD) capability. If 
malfunctions occur in monitored components, Diagnostic Trouble Codes (DTC) will be stored in memory 
together with an indication of malfunction type. A maximum of 4 DTCs can be stored simultaneously. 

Sporadic malfunctions (indicated in the readout by "SP") are automatically cancelled if not repeated in the next 
50 engine starts. 

Before performing any troubleshooting or inspection, always begin by checking for DTCs using the On Board 
Diagnostic (OBD) program. DTCs stored in memory are retrieved/checked with VAG 1551/1552 Scan Tools 
(ST) or VAS 5051 Vehicle Diagnostic Testing and Information System.
