Audi A6 Electronic Parking Brake Failure Alert

Having some experience with brake systems, I faced a similar electronic brake failure on my Audi A4 2.2 from 2002. The symptoms were nearly identical, with the brake sensor showing constant warning lights and a complete system glitch in the parking brake. After running diagnostics, the workshop identified a defective electric motor in the brake calliper. This is actually a common issue in these models where the electronic brake system can fail due to worn components or electrical issues. The repair involved replacing the faulty motor unit and recalibrating the entire electronic brake system. The total repair cost was 505 Euro, including parts and labor. While it wasnt cheap, its crucial for vehicle safety to have this fixed properly rather than trying temporary solutions. To better assist with your specific case, could you provide: Have you noticed any unusual sounds when engaging the parking brake? Did the issue start suddenly or gradually? Are there any other warning lights active besides the brake warning? Have you had any recent brake work done? This information would help determine if youre dealing with the same brake failure issue I experienced or if its something different in your electronic brake system.

Thanks for sharing your experience. My vehicle has 87216 KM and just had its annual service last month. I started noticing a grinding noise when engaging the parking brake about two weeks ago, and the problem developed gradually. The brake fault appeared suddenly yesterday, with only the brake warning light illuminated. No other recent brake work has been performed. Based on your description, it sounds like I might be facing a similar electronic brake motor failure. This helps narrow down the potential issues before going in for brake diagnostics.

This certainly sounds like the same electronic brake motor failure I encountered. The grinding noise you mentioned is a telltale sign, I experienced that exact symptom before my parking brake completely failed. With your mileage and the gradual development of the issue, its highly likely the brake control unit motor has worn out. Your vehicle service history matches the typical pattern where these electronic parking brake issues often surface shortly after routine maintenance. In my case, the grinding started about three weeks before complete failure. The workshop confirmed during my brake diagnostics that once these grinding noises appear, the system glitch is already developing. Waiting too long can potentially cause more damage to the brake control mechanism. Since your symptoms mirror my experience so closely, I suggest getting it checked soon. The repair costs might be similar to what I paid (505 Euro), though prices can vary. Look specifically for workshops experienced with electronic brake systems, as proper recalibration after repair is crucial. After my repair, Ive learned its good practice to regularly engage and disengage the parking brake to help maintain the system, something the technician recommended to prevent future issues.

Given the detailed information you provided about the electronic brake motor failure, I will definitely schedule a repair appointment this week. The grinding noise and progression of symptoms matching your experience gives me a much clearer picture of what to expect. Its reassuring to know this is a known issue with a straightforward fix, even if its not the cheapest repair. I appreciate the tip about regularly engaging the parking brake for maintenance. After investing around 500 Euro in repairs, I definitely want to prevent future brake control problems. Knowing the grinding noise was an early warning sign of brake failure will help me catch any future issues sooner. Just to confirm, after your repair, did you notice any immediate improvement in how smoothly the parking brake engaged? And did the repair completely resolve the brake fault warning on your dashboard? This will help me know what to expect once the work is completed on my vehicle.
