VW Golf Hybrid Cruise Control Failure and Error Codes

Had the same malfunction on a 2016 VW Passat GTE. The cruise control issue typically points to a faulty brake light switch or its wiring harness. The diagnostics revealed multiple stored error codes related to the actuator system. In my case, a thorough inspection showed corroded connections in the main fuse box near the brake pedal assembly. The issue was serious since it affected multiple electronic systems, but the fix was straightforward. The repair involved cleaning the connections and replacing the brake light switch assembly. This is a known issue with VW models from that generation. A specialized VW workshop will know exactly where to look. The car electronics need proper diagnostics equipment to clear all error codes after repair. Make sure they check all cable connections in the brake pedal area and verify the cruise control functionality after repairs. Important to note, temporary fixes like cleaning contacts without replacing worn components often lead to the same problem returning within months. Insist on getting the complete repair done including new connectors if corrosion is found.

Thanks for sharing your experience. My Golf had similar symptoms last year, error messages and non-functional cruise control. The throttle body also started acting up shortly after. My mechanic found the same corroded connections in the fuse box area. Did the repair hold up well over time? I am curious about the total cost of your fix because I paid 450€ at a certified workshop. Also wondering if you had any other electronic glitches pop up since getting it repaired?

Glad to provide an update on my experience. The repair has been completely reliable since getting it fixed properly. The initial malfunction with the cruise control was resolved by addressing a loose cable connection near the brake pedal assembly. Total cost was 95€ for the repair work, which seems much more reasonable than what you paid. The car electronics have been functioning perfectly since the fix, no error codes or throttle body issues have appeared. My mechanic explained that catching these connection problems early prevented more extensive damage to other components. When dealing with non-functional cruise control systems, the key is finding the root cause rather than just clearing error codes. In my case, the simple cable repair proved to be the right solution, and I have had zero electronic glitches since the work was completed. Your 450€ repair cost seems quite high for what was likely a similar issue. Might be worth getting a second opinion if you experience any future problems, as these types of electrical repairs typically shouldnt cost that much unless multiple components need replacement.

Thanks for the input. I finally got this sorted out last week. Took it to an independent workshop that specializes in VW electronics. The mechanic immediately identified the issue with the cruise control actuator and found multiple loose connections. The total repair came to 280€ including diagnostics. They cleaned all connections in the fuse box area and replaced a faulty brake light switch that was causing intermittent malfunction codes. The car electronics are now working perfectly, no more error messages and the cruise control functions as it should. Much better deal than the 450€ quoted at the dealership. The mechanic showed me exactly where the problems were and explained how corrosion had affected the connections. Since the repair, I have not experienced any electronic glitches or system errors. My advice to others with similar issues, find a qualified independent shop with proper diagnostic equipment. They often charge less than dealerships while still doing quality work. Getting it fixed properly the first time saved me from more expensive repairs down the road.
