1998-2004 ACCESSORIES & EQUIPMENT

On Board Diagnostic (OBD) - New Beetle (Instrument Cluster, Data Bus & Anti-theft 

Immobilizer) 

INSTRUMENT CLUSTER UP TO 06.99, ON BOARD DIAGNOSTIC (OBD) 

GENERAL INFORMATION 

The instrument cluster is controlled by an internal microprocessor with On Board Diagnostic (OBD) capability. 
If malfunctions occur in monitored sensors and 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 start cycles. 

For OBD purposes, the instrument cluster counts one start cycle whenever the ignition is switched on longer 
than 5 min. and a minimum speed of 30 km/h (18.5 mp/h) is exceeded. 

Before performing any troubleshooting or inspection, always begin by checking for DTCs using the OBD 
program. DTCs stored in memory are retrieved/checked with either the VAG 1551/1552 Scan Tool (ST) or 
VAS 5051 Vehicle Diagnostic Tester.
