VW Golf Brake Light Switch Fix: DIY vs Shop Options

Had the same brake light switch issue on my 2013 VW Passat TDI. The vehicle safety system kept showing warnings about brake light failure, similar to your symptoms. The automotive switch for the brake lights is indeed a common failure point across VW models. In my case, the brake pedal position sensor was sending incorrect signals, causing intermittent brake light operation. This affected both the brake lights and cruise control functionality. Got it fixed at an independent workshop specializing in VW. The repair involved replacing the complete brake switch assembly, not just the sensor. It was a relatively straightforward fix, taking about an hour of labor. While this wasnt a serious safety concern immediately, leaving it unfixed could lead to complete brake light failure or false brake system warnings. For DIY, the brake light switch replacement is moderately simple if you have basic tools and can access the diagnostic system to clear the error codes. However, given the importance of proper brake light function for vehicle safety, professional installation ensures everything works correctly. The new switch resolved all warning messages and restored proper brake light operation. Definitely worth fixing rather than ignoring the symptoms.

Thanks for sharing your experience with the brake switch replacement. Really helpful info. Quick question, do you remember roughly how much the repair cost at the specialist workshop? Also curious if youve had any recurring issues since getting it fixed. My warning light situation is getting annoying and I want to budget properly for the repair.

Thanks for asking about the costs. Actually, my case turned out differently than expected, when I went to the workshop, they found no electrical issue with the brake switch at all. The problem was simply that the switch had slightly moved out of position due to normal use. The mechanic just needed to properly reseat the automotive switch, no replacement parts needed. Since it was such a quick fix, they didnt even charge me for the inspection. The brake light warnings havent come back since this adjustment. Sometimes what seems like a complex electrical issue turns out to be a simple fix. The important thing is getting it checked out quickly when brake-related warning lights appear, since proper brake light function is crucial for safety. If your situation is different and you do need a complete switch replacement, costs typically depend on the specific parts required for your model. The diagnostic check is worth it either way to determine the exact cause.

Thanks everyone for the suggestions. I finally got this sorted out today! Went to a local German car specialist recommended by a friend. Unlike my previous mechanic experiences, these guys actually took the time to properly diagnose the brake light switch issue. Turns out the electrical issue was indeed a faulty brake pedal switch, just as suspected. The automotive switch replacement was needed but the repair was quick and straightforward. Total cost came to 180€ including parts and labor, which seemed fair given the specialized nature of the work. The brake light warnings disappeared immediately after the switch replacement and everything works perfectly now. No more dashboard alerts popping up during my drive. Really glad I got this fixed properly instead of letting it drag on. Best part is the whole repair only took about 45 minutes. If anyone else runs into similar brake light problems, definitely worth checking the switch first before assuming worse issues.
