Audi Q5 Airbag Warning: Rollover Sensor Fix Guide

I have got a recurring airbag warning light in my 2011 Audi Q5 Hybrid. The diagnostic scan shows an error code related to the SRS sensor system. After some research, I suspect the vehicle rollover sensor might be faulty, as this seems to be a known issue with similar models. Has anyone dealt with similar crash detection system problems in their Q5? Would be great to hear about your repair experiences and what the actual fix was. The warning keeps coming back even after resetting. What should I tell my mechanic to check specifically? Looking for solutions beyond the basic sensor reset.

Had the exact same issue on my 2013 Audi Q7 Hybrid last year. Have some experience working on basic vehicle safety systems, though I always get professional help with complex SRS-related problems. The rollover sensor in these models can trigger false readings, causing the airbag warning to persistently reappear. After multiple failed reset attempts, the diagnostic revealed a faulty control unit connected to the SRS sensor system. The vehicle safety monitoring system kept registering incorrect signals. The workshop replaced the complete control unit module, including recalibration of the vehicle rollover detection system. Total repair cost was 1000 Euro. Since then, zero warning lights or false alerts. Before suggesting specific fixes, could you share: Have you noticed any impact damage near the center console? Does the warning appear more frequently when driving on rough roads? What specific error code is showing in your diagnostic scan? Has your Q5 ever been in an accident? These details would help determine if your issue matches the control unit failure pattern common in these models.

Last service completed at 187708 KM. Thanks for the detailed insight. The diagnostic scan shows error code B0028, and no prior accidents or visible damage to report. The warning seems unusual and not connected to road conditions. I had concerns about a full control unit replacement being overkill, but your experience suggests this might be the right path. The persistent airbag sensor failures despite resets definitely match the symptoms you described. Did your repair include a complete recalibration of all automotive sensors, or just the rollover detection system? Just wanting to ensure all crash detection components work properly after the fix. My mechanic mentioned possible sensor failure in other connected systems that might need checking.

Thanks for those additional details. Based on error code B0028 and the symptoms you described, it definitely mirrors my Q7 experience with the faulty SRS sensor system. In my case, the repair involved a complete recalibration of all connected vehicle safety systems, not just the rollover sensor. The workshop explained that the crash detection components are interconnected, so a full system calibration was necessary to ensure proper function. The complete process included: Replacement of the control unit, Full system diagnostic scan, Calibration of all SRS sensors, Reset and testing of the vehicle rollover detection, Verification of all crash detection systems After the repair, they ran multiple diagnostic tests to confirm all vehicle safety systems were communicating correctly. The thorough calibration process explains part of the repair cost, but it prevented future sensor-related issues. One tip: make sure your workshop uses manufacturer-specified calibration tools for the SRS sensor system. Generic diagnostic equipment might miss subtle communication issues between the crash detection components. Given your mileage and symptoms, a complete control unit replacement with full system calibration sounds like the most reliable fix.

The diagnostic code and unusual warning pattern definitely match the symptoms described. Since there's no accident history or visible damage, a control unit replacement with full recalibration seems like the logical next step. The rollover sensor issues in these models are well-documented, so I'll discuss the complete calibration recommendation with my mechanic. Good point about the manufacturer-specific diagnostic tools for the SRS sensor system. I'll make sure they verify all crash detection systems after the repair, not just the vehicle rollover components. Better to do a thorough job now than deal with ongoing safety system warnings. Will schedule the repair and request full documentation of all calibration steps. Hoping the 1000 Euro estimate holds true for my case. Thanks for helping clarify the right approach for resolving these persistent airbag warning issues.
