VW Bora Brake Switch Failure Causing Multiple Warnings

As a VW Golf 2003 owner, I encountered similar brake switch symptoms last season. The automotive switch malfunction caused sporadic error messages and tail light warnings, though the brake pedal felt mechanically sound. The root cause was a failing brake light switch, a common electrical issue in these VW models. The original switch deteriorates over time, creating false signals to the control unit. Initially, the mechanic cleaned the switch contacts, but this proved to be a temporary fix. The permanent solution required replacing the entire brake switch assembly. This repair was critical for vehicle safety, as a faulty switch can affect multiple systems, including cruise control and brake light function. The job itself is relatively straightforward for an experienced technician, taking about an hour to complete. The new switch must be properly calibrated to ensure correct communication with the vehicle systems. This is actually a recognized issue across several VW models from that era. Getting the correct OEM replacement part is crucial, aftermarket alternatives often lead to recurring problems. Based on the symptoms described, this sounds exactly like the brake switch problem I dealt with. Would strongly recommend having the switch replaced rather than attempting temporary fixes.

Thanks for sharing your experience with the brake light switch issue. Mine got fixed about 3 months ago and works perfectly now. My mechanic also said its really common in VWs and the electrical issue was exactly as you described, unusual warnings and the brake lights acting up. Would be helpful to hear how much you ended up paying for the repair. In my case, they did a full brake system check while they were at it. Just wondering if you had any other issues pop up since the automotive switch was replaced?

Really glad to hear your brake switch got sorted. After my initial reply, I actually discovered the issue was even simpler than expected. When I returned to the mechanic, they found the brake light switch was just slightly out of position, a common user error that can happen over time. A quick adjustment fixed all the electrical issues, and the warning lights disappeared completely. Since the fix three months ago, my brake system has worked flawlessly with no recurring problems. The best part was the repair cost absolutely nothing since it was just a minor adjustment rather than a full switch replacement. If anyone else faces similar brake light switch problems, its worth having a mechanic check the switch position first before assuming replacement is needed. The brake pedal operation and warning signals can be affected by even slight misalignment of the switch.

Got my brake light switch sorted last week after dealing with those annoying tail light warnings. Went to a local garage that specializes in VW electrical issues, way better experience than my first mechanic. The switch replacement took about 45 minutes and cost 85€ including labor. The technician showed me the old switch which was completely worn out. Since the fix, no warning lights have appeared and the brake system works perfectly. They did a quick check of the entire brake system while working on it but found everything else in good condition. Really relieved it was just the switch and not something more serious. Total cost actually ended up being less than the first garage quoted me. For anyone else dealing with similar problems, definitely worth getting a second opinion if you are not confident with the initial diagnosis. The right mechanic makes all the difference with these specific automotive switch issues.
