Audi Q5 Electronic Parking Brake Failure Fix Guide

Had the same brake fault on my 2014 Audi A4 2.0 TFSI last winter. The brake control module showed similar error codes for the electronic parking brake system. The issue turned out to be a failed electric motor in the brake caliper. The brake sensor was reporting correct data, but the motor could not generate enough force to engage the parking brake properly. Vehicle safety was compromised since the parking brake would out of nowhere disengage on inclines. A complete caliper replacement was necessary as the motor assembly is not serviceable separately. The repair involved: Removing rear brake calipers, Installing new electronic parking brake units, Brake diagnostics and coding of the new components, Full system calibration This was a serious repair requiring specialized equipment for proper brake control system programming. Regular brake shops often lack the diagnostic tools needed for electronic parking brake repairs on these models. The fault is relatively common on VAG vehicles with electronic parking brakes from that era. Would recommend having it checked at a shop with proper brake diagnostics capabilities to prevent complete brake failure. The repair resolved all symptoms and restored full parking brake functionality.

Thanks for sharing your experience. The same happened to my 2012 Q5 and it turned out to be a defective brake control module causing the parking brake malfunction. The repair involved a full module replacement and system recalibration. Very interested to know what the total repair cost was in your case and if the electronic parking brake has worked reliably since the fix? My repair happened about 8 months ago and no issues so far, but always good to hear long-term feedback from others who had similar brake system repairs done.

Happy to report that since having the electronic parking brake repaired over a year ago, the system has worked flawlessly without any brake fault warnings or system glitches. The total repair cost came to 505 Euro for replacing the faulty electric motor in the brake caliper. The brake diagnostics confirmed it was definitely the electric motor causing the malfunction, not the brake sensor or control module. While not a cheap fix, the repair restored full vehicle safety and parking brake reliability. The investment was worth it to eliminate the risk of unexpected brake failure. The electronic parking brake now engages smoothly every time, and the warning lights have stayed off. Based on my experience, once the actual faulty component is properly diagnosed and replaced, these electronic brake systems tend to remain stable long-term.

I finally got it fixed last week after dealing with the faulty parking brake for months. The mechanic found a failed brake switch which was causing intermittent engagement issues with the electronic parking brake. Total repair cost was 320 Euro including brake diagnostics and parts. Getting a proper diagnosis made all the difference. The first shop I went to simply cleared the fault codes without fixing the underlying brake sensor problem. This time I found a specialist who actually took the time to properly test the parking brake system components. The repair process was straightforward once they identified the real issue: Full system diagnostic scan, Brake switch replacement, Control module recalibration, Road test to confirm proper function The parking brake now engages reliably and all warning lights are off. Really glad to have resolved the vehicle safety concern. Looking back, I should have gone to a qualified specialist right away instead of wasting time with basic diagnostics at regular shops. Thanks for sharing your experiences. The feedback helped me better understand what to look for in finding the right repair solution.
