VW T-Roc Cruise Control Malfunction Troubleshooting

Having some experience with VW models, I faced an identical malfunction on my 2020 VW T-Cross with the cruise control system. The symptoms were exactly the same, error messages and complete failure of the cruise control. After checking fuses like you did, I took it to a workshop where they found a faulty system connection. The diagnosis revealed loose cable connections at the steering wheel controls, affecting the cruise control actuator. Car electronics can be sensitive to these connection issues, and they often cause similar symptoms across VW models. The fix was straightforward, they repaired the cable connection and did a system reset. Total cost was 95€ including diagnosis and repair. The cruise control has worked flawlessly since then. Could you share: Current mileage on your T-Roc? Does the error message appear immediately when starting the car? Are other steering wheel controls working normally? Have you noticed any other electrical issues? This information would help determine if youre dealing with the same root cause.

My mileage is 131290km. The error message appears about 30 seconds after starting the car. Other steering wheel buttons work fine, except the voice control occasionally acts up. The throttle body seems to operate normally and acceleration is smooth. After reading your experience, I did notice the cruise control buttons feel a bit loose compared to other steering wheel controls. Will definitely have the workshop check those connections during diagnostics. Hopefully its a simple fix like yours and not a complex faulty system issue. Thanks for the detailed info, helps narrow down where to look first.

Thanks for those details. Since your symptoms match what I experienced, Im increasingly confident its a connection issue, especially with your observation about loose cruise control buttons. The voice control acting up actually strengthens this theory, as both functions often share wiring paths through the steering wheel electronics. With your mileage being 131290km, wear on the steering wheel wiring harness is common. The 30-second delay in the error message is typical for connection problems, as the car electronics run through system checks after startup. Quick update on my repair, after 50000km since fixing those loose connections, no issues have returned. The workshop followed the proper diagnostics sequence: 1. Checked fuse box connections 2. Tested steering wheel wiring continuity 3. Inspected cruise control actuator signals 4. Performed full system reset Total repair time was under 2 hours. If your repair costs exceed 200€, request a detailed breakdown, as connection repairs shouldnt be too expensive unless they find additional issues. Just keep in mind that completely worn wiring might need replacement rather than just reconnection, but thats less common with these models.

Just checked my T-Roc, mileage currently shows 131290km. The error message consistently shows up around 30 seconds after starting the car. All other steering wheel functions work as they should, though the voice control does sometimes act erratically. The throttle body operation seems normal with smooth acceleration response. After reviewing your explanation, I checked the cruise control buttons more carefully and noticed they do feel looser compared to other controls on the steering wheel. This seems to align perfectly with the connection issue you described. Will definitely ask the workshop to focus on checking those wire connections during their diagnostics. Really hoping its just a straightforward connection fix like in your case rather than a more complex system problem. The fact that my symptoms match yours so closely, including the delayed error message and partial steering wheel control issues, makes me more confident about what to expect at the workshop. Your repair price point gives me a good reference for what I should expect to pay. Will schedule an appointment this week and have them check those specific areas you mentioned. Thanks for helping narrow down the likely cause.
