Audi SQ5 Steering Controls Dead, Troubleshooting Guide

Recently dealt with a similar multifunction steering malfunction in my S4 (2016, 3.0 TFSI). The connectivity problem started with intermittent button response before complete failure. The root cause was a worn cable in the steering wheel clock spring assembly. This is a common electrical fault that occurs when the ribbon cable inside the steering column gets damaged from repeated turning movements. The malfunction indicator showed up after complete failure. The repair required: Complete removal of steering wheel, Replacement of the clock spring unit, Testing of all control functions, Clearing sensor issue codes This is considered a critical repair since the clock spring also handles airbag connectivity. The fix restored full functionality to all steering controls including audio, phone, and menu navigation. Worth noting, if you hear clicking sounds when turning the wheel or notice intermittent function before total failure, these are typical warning signs. Best to address this soon as it can affect other steering wheel mounted systems. A proper diagnosis will confirm if its the same clock spring issue, but the symptoms match exactly what I experienced.

Thanks for sharing your experience. My SQ5 had the exact same control module failure symptoms, no response from any steering wheel buttons. The vehicle diagnostics also pointed to the clock spring like in your case. Did you remember roughly what the repair costs were? And have you experienced any connectivity problems since getting it fixed? Just want to make sure the fix was truly permanent before I commit to the repair.

Happy to report my repair experience was completely successful. The control module connectivity issue in my S4 was permanently resolved. Since getting the clock spring assembly fixed at the garage, all multifunction steering controls have worked flawlessly. The total bill came to 95 Euro for fixing the faulty cable connection in the steering wheel. The vehicle diagnostics were spot on in identifying the issue and the sensor issue was resolved in a single shop visit. Looking back, the repair was straightforward and worth every cent given how much I rely on those steering column controls daily. For peace of mind, its been several months now without any signs of the previous connectivity problems returning. The buttons remain responsive and the error messages haven't reappeared.

Thanks for the input. I finally got my SQ5 fixed last week. The mechanic confirmed it was indeed the clock spring causing the multifunction steering failure. The repair took about 2 hours, they had to remove the steering wheel to access the faulty unit in the steering column. Total cost came to 480 Euro including parts and labor. A bit more than expected but the connectivity problem is completely resolved. All buttons are working perfectly now and the malfunction indicator is gone. The shop also showed me the old clock spring, the ribbon cable was visibly damaged from wear. Makes sense given the high mileage. Happy to report no issues since the repair and everything feels solid. The steering controls for audio and phone work like new again. Definitely recommend getting this fixed promptly if anyone else experiences similar symptoms. The mechanic mentioned leaving it too long risks damaging other steering wheel components.
