Telematics System, troubleshooting using OnStar system status light

WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2008 Audi S4, 2008 Audi RS 4, 2008 Audi A4, 2007 Audi S4, and 2007 Audi RS 4. However, it is still accessible from the selected car via links, so may be relevant.

The following allows technicians to perform an initial evaluation of telematics system operation status for troubleshooting using the OnStar system status light (and pre-recorded system messages where applicable).

NOTE:

After pressing either the OnStar or Emergency button, a recorded message announces: "connecting to OnStar," followed by progression tones. Normal connection time is 10 - 15 seconds. However, due to local cellular/GPS conditions, making a connection could take up to three minutes. Be patient.

Condition - system status light "green" plus:

Message "unable to connect to OnStar" and disconnect
Message "OnStar request ended"
Nothing happens
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 vehicles cellular/GPS antenna system also affects connectivity.

Check all cellular/GPS antenna connections, and perform OBD program using VAS 5051/5052 in mode "Vehicle Self Diagnosis" or "Guided Fault Finding". Check for DTCs related to antenna function.

If still unable to connect:

Record the VIN and customer details and call OnStar Customer Care at 1-888-390-4050. Identify yourself to the advisor as an Audi technician. The advisor will verify the customers account is active. Further troubleshooting assistance may be given.

Condition - system status light "red" :

System hardware (vehicle portion) is affected. Perform OBD program → On Board Diagnostic (OBD), function

NOTE:

In the event any of the OnStar 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 5051/5052 and check DTC memory for DTC 01526 "mechanical malfunction". Inform customers accordingly.
