Volkswagen New Beetle. Manual - part 405

message "OnStar(R) request ended",

nothing happens,

or a cellular message

indicates system cellular reception is affected. Proceed as follows:

Relocate vehicle to a more elevated or open area and repeat connection attempts. Depending on the local
cellular/GPS traffic conditions, several connection attempts may be necessary (and are normal).

Shortcomings in the vehicle's cellular/GPS antenna system also affects connectivity. Check all
cellular/GPS antenna connections, and perform OBD program using VAS 5051 Vehicle Diagnostic
Testing and Information System in mode "Guided Fault Finding". Check for DTCs related to antenna
function.

If you are still unable to connect, record the VIN and customer details and call OnStar(R) Customer Care
at 1 -888-390-4050. Identify yourself to the advisor as an Volkswagen Technician. The advisor will
verify the customer's OnStar(R) account is active. Further troubleshooting assistance may be given.

Condition - telematics indicator lamp "red"

indicates system hardware (vehicle portion) is affected. Proceed as follows:

Perform OBD using VAS 5051 Vehicle Diagnostic Testing and Information System in mode "Guided
Fault Finding". Check/perform:

DTC memory (function 02)

Output DTM (function 03)

Read Measuring Value Block (function 08)

TRANSPORT MODE DEACTIVATING

The Telematic system is disabled (switched-off) when Transport Mode is activated. This is necessary when
vehicles are transported over long distances or stored for longer periods of time.

Some Volkswagen vehicles are initially delivered to dealerships with the Telematics system in Transport Mode,
and must be deactivated before delivery to the customer using OBD program (VAS 5051 Vehicle Diagnostic
Testing and Information System in mode "Guided Fault Finding".)

NOTE:

In the event any of the OnStar(R) control buttons are either inadvertently or
deliberately pressed for longer than 15 seconds, the OBD program assumes a
button is sticking. The red status light will come on and a DTC loads in memory.
Perform OBD program using VAS 5051 Vehicle Diagnostic Testing and
Information System in mode "Guided Fault Finding". Check DTC memory for
DTC 01526 "mechanical malfunction". Inform customers accordingly.

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.

Complaint/symptom based Technical Bulletins ("Service Fixes"): Check for Technical Bulletins.

Notes on exchanging instrument cluster

Do not disassemble instrument cluster.

When replacing an instrument cluster is necessary, follow normal exchange part procedures.

Complete report form and return together with instrument cluster.

Use original packaging from new cluster when returning items.

Replacement instrument clusters must first be coded according to vehicle market version and equipment
level variables using VAG 1551 Scan Tool (ST)

Odometer reading must also be adapted to the replacement instrument cluster. See ODOMETER
READING UP TO 06.98 MODELS, ADAPTATION .

NOTE:

The following description and illustrations deal specifically with the VAG 1551
scan tool. VAG 1552 and VAS 5051 procedures are similar.
