VW Sharan Cruise Control Failure After Mechanic Visit

Had the same problem on my 2006 VW Touran diesel. The cruise control failed completely while driving, showing warning lights on the dash. After investigation, it turned out the brake light switch was faulty, which is a common issue affecting the cruise control system. The speed sensor connection at the transmission was also loose, causing intermittent failures. These components work together, the brake light switch tells the system when to disengage, while the speed sensor provides crucial data to maintain steady cruise speeds. This wasnt a major repair but required proper diagnostic equipment to pinpoint the exact issue. The fuse box should be checked first since its the simplest fix, but in my case the problem went beyond that. A qualified mechanic needed to access diagnostic codes and test multiple components including: Brake light switch functionality, Speed sensor connections, Steering wheel cruise control buttons, Related fuses and wiring Would suggest having a professional check it since cruise control issues often connect to other important safety systems. Getting it fixed properly the first time prevents recurring problems.

Thanks for sharing your experience. My 2003 Sharan had a similar cruise control failure last year. After checking the fuse box and finding nothing obvious, it ended up being the clock spring behind the steering wheel that was causing the intermittent connection issues. Could you share what repair costs were in your case? Also curious if the speed sensor or other related systems gave you any trouble since getting it fixed?

After my mechanic properly diagnosed the issue with my VW Touran, the cruise control has worked flawlessly. The repair ended up being much simpler than initially suspected, just a loose connection that needed securing rather than a complete component replacement. Total cost was 95€ including the diagnostic work. No problems at all with the speed sensor or any related systems since the fix. Unlike your situation with the clock spring behind the steering wheel, my issue was purely an electrical connection problem. Its nice when these cruise control issues turn out to be straightforward fixes rather than major component failures. The diagnostic process was thorough though, they checked the entire cruise control system including the fuse box, steering wheel controls, and all connecting wires to ensure there werent multiple issues at play. Definitely worth having a proper inspection done rather than just guessing at the problem.

Thanks for the helpful advice. I took my Sharan to a new mechanic who specializes in VW electrical systems. After a full diagnostic check, they found my cruise control failure was caused by a worn pedal switch that was sending faulty signals. The repair was straightforward, just needed a new brake pedal switch installed and some electrical connections cleaned up. Total cost came to 145€ including parts and labor. No issues since the fix was done 3 months ago. Much better experience than my last mechanic who kept replacing unusual parts without proper diagnosis. The blown fuse theory made sense but Im glad I had it properly checked instead of just guessing. Always good to find a mechanic who takes the time to diagnose things correctly.
