Audi TT Airbag Warning: Rollover Sensor Alert Fix
Summary of the thread
The conversation centers around an airbag warning light issue in a 2019 Audi TT, suspected to be caused by a faulty rollover sensor. The problem was confirmed by a diagnostic scan, revealing water damage to the sensor. The solution involved replacing the SRS sensor unit, fixing a leak, and recalibrating the safety system, which resolved the issue without further warning lights. The advice to address the problem promptly helped avoid more significant complications.

Thanks for sharing your experience with the airbag sensor problem. My TT had almost the exact same issue last year, the tilt sensor malfunction triggered the warning light. Good to know about the wiring harness being the culprit in your case. How much did the complete SRS sensor repair end up costing you? Also curious if youve had any other warning lights or safety system problems since the fix?

Glad I could help with the sensor issue insight. The complete repair of the SRS sensor system and vehicle rollover detection unit came to 1000 Euro total. Since having the faulty control unit replaced and recalibrated, the automotive sensor system has worked flawlessly, no warning lights or safety alerts for over 8 months now. The mechanic explained that these vehicle safety components are quite robust when properly maintained, but once they start failing, its crucial to address them quickly. The rollover sensor malfunction was completely resolved after replacing the affected control unit. Looking back, the repair cost was worth it for the peace of mind knowing the crash detection system is functioning correctly. No other issues with any safety systems since the fix, all sensors are communicating properly with the main control unit now.

Just got back from the mechanic and wanted to update. Turns out it was indeed a faulty rollover sensor causing the airbag warning. The total repair came to 850 Euro, which included a new SRS sensor unit and labor costs. The diagnostic scan showed the original sensor had water damage from a small leak near the mounting point. They fixed both issues and recalibrated the entire safety system. The whole process took about 3 hours. Best part is, no warning lights since the repair and the crash detection system is working perfectly now. Really appreciate the advice about getting it checked right away, definitely saved me from bigger problems down the road.

Had a similar issue with my 2016 Audi S3. The airbag warning light activated due to a faulty SRS sensor connection. Initially thought it was just a rollover sensor, but diagnostic testing revealed more complex crash detection system problems. The safety system needed complete inspection since faulty airbag sensors can prevent proper deployment during accidents. The root cause was a corroded wiring harness affecting the control unit. The repair involved: Full diagnostic scan of all safety modules, Removal and replacement of affected control unit, Recalibration of the airbag sensor system, Testing of all crash detection components This is considered a serious safety issue requiring immediate attention. The repair process took about 4 hours in total. Driving with compromised airbag sensors puts passengers at risk since the system may not respond correctly during an incident. Suggest having a certified technician perform a complete diagnostic scan. Sensor failure in these models often indicates underlying electrical issues that need professional assessment. Make sure they check both the rollover sensor and surrounding components, as the initial warning light can sometimes mask bigger problems.
