Audi A5 E-Brake Failure: Warning Signs & Repair Guide

Had the same brake fault on my Audi A4 2016 with similar symptoms. The brake control unit detected a defective electric motor in the brake caliper, which caused the electronic parking brake to malfunction. The repair involved replacing both rear brake calipers since the electric motors are integrated into the caliper assembly. This is a serious issue that needs immediate attention, as a failing electronic parking brake can create unsafe situations. Main symptoms matched yours: Warning light activation, System completely unresponsive, Stored fault codes in brake control module The repair process required: Full diagnostic scan, Brake caliper replacement, Control module reprogramming, System calibration Worth noting that brake sensor issues can sometimes trigger similar warnings, but in most cases with these symptoms, its the caliper motors that fail. The system glitch you describe is a known weak point in these models. Recommend having it checked soon, as continuing to drive with a brake failure warning could lead to parking brake engagement issues or complete failure.

Thanks for sharing that detailed info about the caliper replacement. I had that exact brake fault with my A5 about 8 months ago and went through a similar repair process. The brake diagnostics showed the same parking brake motor failure. Really appreciate the thorough breakdown of the repair steps. Mind sharing what the total repair cost was for you? Just wondering how it compares to what I paid. Also curious if youve had any other brake control issues pop up since getting it fixed? My repair has held up well so far but always good to know what to watch out for.

Had the complete repair done last week at the shop. The electronic parking brake is working perfectly now. The brake diagnostics confirmed what we suspected, faulty electric motor in the caliper was causing the system glitch. Total cost came to 505 Euro for the repair, which included replacing the defective brake components and reprogramming the control module. Since the fix, no more warning lights or brake failure messages have appeared on the dash. The electronic brake system has been functioning flawlessly, smooth engagement and release every time. Regular maintenance and keeping an eye on the brake switch signals should prevent similar issues from developing again. This type of repair tends to be a permanent solution when done correctly.

I finally got the brake control system fixed last month after seeing your posts. The mechanic found exactly what you described, faulty motors in the brake calipers. The brake diagnostics confirmed it right away. Ended up paying 580 Euro for the complete repair, which was actually less than I expected after reading about others experiences. The vehicle safety inspection showed everything else was fine, just those problematic caliper motors. The whole repair took about 4 hours. They replaced both rear calipers, ran a full system check, and recalibrated the brake control unit. Everything works perfectly now, no more warning lights or error messages. Really glad I got it sorted. The electronic parking brake engages smoothly every time now. Definitely learned my lesson about getting brake system warnings checked out promptly rather than waiting.
