Audi A2 Cruise Control Fix, Common Fault Solutions

As someone with some experience working on VAG diesel engines, I dealt with a very similar issue on my 2003 Audi A3 diesel. The symptoms were identical, complete cruise control failure with error codes showing up. After taking it to my regular workshop, they diagnosed a faulty clock spring in the steering wheel assembly. The connection between the steering wheel controls and the main system was intermittent due to worn wiring. This component handles multiple functions including the cruise control buttons and airbag connections. The repair was straightforward, they replaced the clock spring unit and cleared the error codes. Total cost was 95 Euro including labor. The cruise control worked perfectly after the fix. Before suggesting specific solutions for your A2, could you share: Current mileage, Whether the airbag warning light is also illuminated, If other steering wheel controls still work normally, Whether you notice any clicking sounds when turning the steering wheel The speed sensor and other related components might also need checking, but knowing these details would help narrow down if your issue matches what I experienced. Just note that a proper diagnostic scan is essential since similar symptoms can have different root causes. A dashboard light check might reveal additional helpful information.

Just had my service done last week at 111337 KM. In my case, it turned out to be a combination of issues with the pedal switch and a blown fuse linked to the cruise control system. The pedal switch was causing intermittent connection problems, and the fuse had blown as a result. After both were replaced, everything works perfectly again. Cost was around 180 Euro total, 120 Euro for the pedal switch and 60 Euro for labor. Worth checking these simpler fixes before looking at more complex issues like the clock spring or wiring harness problems.

Thanks for sharing your resolution. That is a much better scenario than my clock spring replacement. The fuse box and pedal switch combo is indeed a common failure point that I should have considered first for cruise control issues. When my A3 had similar problems, I went straight to the more expensive fix without checking these basics. Looking back, I probably could have saved money by checking the cruise control fuses and pedal switch first. The throttle position sensor and related switches tend to cause these kinds of intermittent issues more often than wiring problems. Your repair cost was still reasonable at 180 Euro though. Good to know the simpler fix worked for you. This will definitely help me troubleshoot better if my cruise control acts up again. The dashboard light scan you had done during service probably helped pinpoint the exact issue quickly. Much more efficient than my experience where we had to test multiple components.

Great to update everyone on the outcome. Wanted to mention that the service center did a really thorough job with the diagnostic scanning which helped identify both issues quickly. The pedal switch ended up being the primary culprit causing the cruise control to fail, and the blown fuse was just a result of that initial problem. For anyone facing similar issues, definitely check your fuses first, it is a quick and cheap potential fix. The dashboard light patterns can also provide good clues. In my case, the throttle position remained normal during regular driving, which helped rule out more serious problems with the speed sensor systems. The 180 Euro total cost was reasonable considering it fixed the problem completely. The pedal switch replacement at 120 Euro plus 60 Euro labor actually saved me money compared to some of the more complex repairs others have needed. Really glad I got this sorted before any additional components could be damaged.
