Smart Roadster Steering Controls Malfunction Fix Alert

I had a similar electrical fault on my 2002 Smart Fortwo. With some experience working on basic car maintenance, I faced nearly identical multifunction steering issues last summer. The control module stopped responding completely, no horn, no audio controls, nothing. The diagnostic scan showed steering column communication errors, pointing to connection problems. Took it to a workshop where they found a worn cable connection in the steering wheel, causing intermittent sensor issues. The repair involved replacing the spiral cable assembly connecting the steering wheel controls to the main harness. Total cost was 95€ including diagnostics and labor. The fix completely resolved the problem and all functions are working properly since then. These steering wheel control failures are relatively common on this platform due to wire fatigue from constant turning. What trim level is your Roadster? Also, when did these symptoms first appear, was it gradual or sudden? This info would help determine if you are dealing with the same root cause. The repair is usually straightforward if caught early, but leaving it too long can lead to more extensive control module damage.

Had my 2004 Roadster serviced just last month at 138081 KM. This appears to be the exact same malfunction indicator problem you described. In my case, the sensor issue traced back to corroded contacts inside the steering wheel control module. A full diagnostic scan revealed the connection breakdown between the steering controls and main computer. Workshop replaced the complete control module assembly rather than attempting contact repair. Parts and labor came to 280€. All steering wheel functions have worked flawlessly since the fix. The malfunction was definitely worth addressing promptly to prevent more extensive electrical issues down the line.

Thanks for sharing those details about your Roadster repair. Interesting that your workshop went straight for the full control module replacement, while in my case they determined the spiral cable was sufficient. Your 280€ repair does make sense though, since corroded contacts usually indicate more widespread connectivity problems in the module itself. I will keep monitoring my steering controls closely since these sensor issues seem to be a common failure point in our models. The vehicle diagnostics clearly showed similar error codes in both cases, even if the root causes differed slightly. Good call getting it fixed quickly, I have seen cases where ignored steering column faults led to complete system failures and much costlier repairs. These early-2000s Smart models do seem prone to electrical gremlins, but at least the fixes are generally straightforward once properly diagnosed. Have all the steering wheel functions remained stable since your repair? No intermittent issues? My repair has held up well for 8 months now with zero problems.

Thanks for confirming, your repair experience mirrors what others have reported. The steering wheel functions have been completely stable since the control module replacement. No intermittent electrical faults or sensor issues at all. The vehicle diagnostics were spot-on in identifying the exact problem. While 280€ felt steep initially, the multifunction steering working reliably again made it worthwhile. Much better than risking more extensive electrical problems. Actually planning to have the car back at the workshop next week for its scheduled service. Will have them double-check all the steering column connections just to ensure everything remains properly sealed against future corrosion. This has been really helpful comparing repair experiences. Nice to know both the spiral cable and full control module replacement are viable fixes depending on the specific fault condition.
