Audi Q4 e-tron Handbrake Failure Leaves Owners Stranded

As an Audi Q6 e-tron owner, I encountered similar electronic parking brake issues last month. The brake control system failure symptoms matched exactly what you described, complete parking brake failure and warning lights. The root cause turned out to be a defective electronic brake motor in the rear caliper. This is actually a serious vehicle safety concern that requires immediate attention, as the parking brake might engage or disengage unexpectedly. The repair involved replacing the complete brake caliper assembly with the integrated electronic motor. This was not a simple brake switch replacement or system reset as initially suggested by diagnostic scans. Proper diagnosis required specialized equipment to test the electronic brake module communication. The repair shop found that while the brake control unit was functional, the caliper motor had failed completely. Based on your description and mileage, this sounds very similar to what I experienced with my Q6. These electronic parking brake systems are complex but generally reliable. When they do fail, its typically the actuator motor rather than the main control unit. The repair should include: Full diagnostic scan, Electronic brake caliper replacement, System calibration, Brake function testing This is not something that typically resolves itself and requires proper repair by a qualified technician with the right diagnostic equipment.

Thanks for the detailed explanation of the electronic brake issues. My Q4 e-tron also showed those exact symptoms last year. After a complete brake diagnostics test, they found a faulty control module causing the system glitch. The brake failure warning kept coming on out of nowhere before the fix. Have you noticed any other problems since the repair was completed? Just curious how the fix has held up longer term. Also, what was your final repair cost if you dont mind sharing? My bill came to around 890 Euro but prices seem to vary quite a bit for electronic brake work.

Good news to share about my Q6 e-tron brake repair. Since having the electronic brake caliper motor replaced, the system has been working flawlessly with no recurring brake fault warnings or issues. The brake control system now functions exactly as it should. The total repair cost came to 505 Euro, which included the replacement electric motor for the brake caliper, complete system diagnostics, and recalibration. This was actually lower than your repair since they only needed to replace the motor component rather than the entire control module. The vehicle safety inspection confirmed everything was properly fixed, no more system glitches or warning lights appearing on the dash. The brake diagnostics showed all systems communicating correctly after the repair. Its been about 6 months since the fix, and the electronic parking brake has performed reliably in all conditions. No other brake-related problems have emerged. The initial fault seems to have been completely resolved with the caliper motor replacement. Your 890 Euro cost makes sense if they had to replace the full control module. These electronic brake systems can have different failure points, which impacts the final repair price.

I finally got my Q4 e-tron back from the shop yesterday after dealing with those electronic brake issues. The brake sensor system detected multiple faults during their testing. Just like you mentioned, the electronic parking brake would out of nowhere engage and disengage. After a thorough brake diagnostics scan, they found the control module needed replacement, exactly what you experienced. The repair took about 4 hours total including system testing and calibration. The mechanics had to order a specific brake control unit which added an extra day to the repair time. The total came to 890 Euro which included: New electronic brake control module, Complete system diagnostics, Calibration and testing, Labor costs The vehicle safety inspection confirmed everything is working properly now. No more warning lights or system glitches. Really glad to have this fixed as those unusual brake issues were quite concerning. The repair shop did great work making sure all the brake systems were communicating correctly before releasing the car. Thanks again for sharing your experience. It helped confirm I was on the right track with the diagnosis and repair approach.
