Faulty Rollover Sensor Triggers SQ5 Airbag Warning

I had a similar issue with my 2015 Q5 when the airbag warning light came on. Having some experience with these Audi models, I understand how concerning SRS sensor warnings can be. The crash detection system in my case showed similar symptoms. After scanning, it turned out the airbag sensor control unit was defective and needed replacement. The safety system warning persisted until the repair was completed. The workshop diagnosed it using professional diagnostic equipment to verify the tilt sensor and other components were functioning correctly. The repair involved replacing the control unit and recalibrating the entire SRS system. Total cost was around 1000 Euro including parts and labor. Before suggesting specific solutions for your SQ5, could you share: Current mileage, Any recent accidents or impacts, Whether the warning light is constant or intermittent, If you have access to the specific error codes, Any other warning lights present This information would help determine if your issue matches what I experienced or if it might be something different in the crash detection system.

Thanks for the detailed response. My vehicle has 11640 KM and just had its regular service last month. The warning light is constantly on, and I havent had any accidents or impacts. The diagnostic scan shows error code B101513, which points to the rollover sensor. No other warning lights are active. The airbag sensor issue started suddenly during normal driving. Good to know the control unit replacement fixed your sensor failure. Since the symptoms match and these SRS sensor problems seem relatively common, I might need to prepare for a similar repair cost.

The error code B101513 you mentioned definitely points to the rollover sensor, just like I suspected when I had my issue. While my initial diagnosis led to the control unit, having this specific code helps narrow things down considerably. Looking at the mileage and service history you shared, this sounds exactly like the vehicle rollover detection system fault these models sometimes develop. Since your warning is constant like mine was, and the diagnostic points specifically to the tilt sensor, you might actually be looking at a simpler fix than what I needed. The rollover sensor itself typically costs around 300 Euro-400 Euro, significantly less than the full control unit replacement I had to get. Labor should be about 2 hours since accessing the sensor requires removing some interior trim panels. One thing I learned from my experience, make sure the workshop performs a full system calibration after replacing any crash detection components. My first repair attempt skipped this step, and the warning light came back within a day. Given the similarities to my case, I recommend having it checked soon. While the airbag system remains partially functional, a sensor failure in the rollover detection system could affect proper deployment in an emergency.

Thanks for sharing your experience and insight on the specific error code B101513. My mileage is indeed quite low at 11640 KM with regular maintenance, and the constant warning light matches what you described. Having no accidents or impacts does suggest a sensor failure rather than crash damage. Your point about the rollover sensor being the likely culprit matches the diagnostic results. The 300 Euro-400 Euro cost estimate for just the sensor is much better than a full control unit replacement. Good tip about ensuring proper calibration of the vehicle safety systems after repair, I will definitely mention this to the workshop. I will schedule the repair soon since I understand the importance of having fully functional crash detection and SRS sensor systems. Better to address these vehicle rollover protection issues promptly rather than risk compromised safety features. Will update once the repair is completed in case others experience similar warning lights or sensor problems in the future.
