Default Parking Brake Fault

Symptom - Parking failure on centre display and loud beep whilst driving. If scanning with VAGCOM there will be no voltage from one of the calipers.

[b]Resolution[b] - New brake caliper required complete and possibly new parking controller. Will require coding on reinstall.

Failed parking motor most likely. It will be unable to see the right or left supply channel voltage.

Otherwise parking ECU.

Ensure you have the latest software on the module or replace the module. Worke for me.

How do you establish if it is the caliper or the ECM? Is swapping around the calipers for testing a possibility, or even simply plugging in the working caliper to the other side?

My local garage tested for voltage going to the connector, but nothing showed up even on the side that is working.

Does the caliper move in and out with the motor?

Can you plug VCDS in and perform the tests?

Is the ECM attached to the caliper? I thought it was in the boot.

The caliper does not move and the motor does nothing. VCDS reports:
