Service

1.

Please check first whether the vehicle has the most recent up-to-date software version. Reassess the complaint after successfully performing any open campaign(s).

2.

Check the following:

a.

Are privacy settings active?

b.

Is mobile data activated?

c.

Are messages relating to the emergency call shown in the instrument cluster?

d.

Which mobile phone reception icon can be seen on the MMI screen.

3.

Take a photo of the MMI screen, ensuring that the mobile network reception icon can clearly be seen. Please also photograph the roof module with the emergency call and online roadside assistance call status LED. Photograph any messages that are actively shown in the instrument cluster.

4.

Perform a Terminal 30 reset on the vehicle, letting it sit for one minute, then cycle on. If not corrected, reset the control module in Service Portlet under the Vehicle Communication Tab.

5.

Read all measured value blocks for 0075 emergency call module and send the log. Search for the measured value “GPS Time” in the measure value blocks and find the measure value “status” below it. This status must be “valid”. Then, search for the measured value “Radio_Cell_Number_Textual” and find the measured value “Status” below it. This status must be “valid”. If the status of at least one of the two values is “invalid”, make sure that you have connected the vehicle to the internet outside and with sufficient mobile phone reception. If so, check the antennae wiring at J949. To do so, we recommend connecting a “flying” antenna in addition to performing an electrical measurement on the wiring. This involves connecting a separate GPS and LTE antenna directly to the J949 with separate antenna cables.

6.

If this does not correct the issue, please open aLevel 2 ticket with Audi DBS.

7.

DoNOTcharge the customer for the antenna. Please us it as a future tool for other repairs.
