Audi A2 Parking Brake Failure Needs Urgent Fix

Encountered a similar electronic brake failure on my 2004 Audi A3 2.0T. The brake control module showed error codes pointing to a faulty motor in the brake caliper. The issue started with intermittent parking brake engagement, followed by complete failure and warning lights. The brake diagnostics revealed the electronic brake actuator motor had seized. This is a serious safety concern as the parking brake becomes completely non-functional. The repair required replacing the entire brake caliper assembly with the integrated electronic motor unit. The root cause was a combination of age and moisture damage to the brake sensor connections. Poor maintenance from previous repairs can accelerate this issue, especially if brake service was done incorrectly or wire connectors were damaged. Two key steps for diagnosis: 1. Full electronic brake system scan to identify specific motor failure codes 2. Resistance testing of the actuator wiring to confirm motor failure For an A2 of that age, this is a common wear point in the electronic brake system. Recommend having a certified shop with proper diagnostic equipment handle the repair, as incorrect installation can lead to further brake control issues. The repair is not a quick fix and requires specialized tools to recalibrate the new brake actuator after installation.

Hey, experienced pretty much the exact same system glitch with my A2 last year. The brake fault diagnosis also pointed to actuator problems, and honestly that previous report sounds spot on to me. Since you got yours diagnosed, I was curious if you went ahead with the repairs? Would help to know what the final cost was, and if you noticed any other brake sensor problems crop up afterwards. Vehicle safety wise, I had to park mine on a level surface with wheel chocks until it got fixed, which was pretty inconvenient.

Just had the electronic parking brake repair completed last week. The system glitch is now fully resolved after replacing the faulty brake actuator motor in the caliper. Total cost came to 505 Euro for parts and labor, which included recalibrating the brake control system. The parking brake now engages smoothly and the warning light has disappeared completely. No additional brake sensor issues have emerged since the fix. The repair shop confirmed the original diagnosis was accurate, the electric motor in the brake caliper had failed due to wear and moisture exposure. The electronic brake system now functions perfectly, engaging and disengaging without any problems. It was definitely worth addressing promptly given the safety implications. Having a properly working parking brake again means no more wheel chocks or hunting for level parking spots. Keep in mind regular brake system maintenance can help prevent similar electronic brake failures in the future. The repair shop should perform a full calibration check after any work on the brake control components.

Thanks for the input. Finally took my A2 to a certified shop last week after dealing with the brake failure symptoms. The mechanic found corroded wiring had damaged the brake actuator, leading to the system glitch. They replaced both the wiring harness and actuator motor. Total repair came to 580 Euro including labor and recalibration. The brake sensor is now working perfectly and all warning lights are gone. The electronic parking brake engages smoothly again which is a huge relief for vehicle safety. The shop also identified the previous mechanic had improperly sealed some brake control connections during routine maintenance, which likely contributed to the corrosion. Definitely learned my lesson about using qualified techs for electronic brake work. Really glad to have this sorted, no more stressing about finding flat parking spots. The repair cost was worth it for the peace of mind.
