Audi S4 Emergency Call System Fix & Reset Guide

A similar emergency call system malfunction occurred on my 2019 Audi S5. The telematics control module showed identical symptoms with warning lights and constant error messages in the instrument cluster. Initially tried basic system reset procedures through the infotainment menu, but the issue persisted. After proper diagnosis, the root cause was a damaged wiring harness connector at the control module. The connection had deteriorated due to normal vibration and heat exposure in the engine bay. The automotive electronics repair required specialized diagnostic equipment to properly identify the fault codes. The fix involved replacing the entire wiring harness segment and reprogramming the emergency call module to restore full functionality. This is considered a safety-critical system since it handles automatic emergency services contact during accidents. Recommend having it addressed at a shop with proper diagnostic capabilities for modern vehicle electronics. The repair complexity requires technical expertise beyond basic mechanical skills. The complete repair process, including system testing and validation, took about 4 hours of labor. While not a severe mechanical issue, its safety implications make it a priority repair item requiring proper attention.

Thanks for the detailed feedback on the emergency call malfunction. This helps a lot as I was getting similar SOS signal errors on my S4. The call failure issues were quite concerning since its a safety feature. Got the diagnostic codes checked last week and they pointed to the same wiring harness problem. Will probably go ahead with the repair based on your experience. Quick question, do you remember roughly what the total repair cost was? Also, has everything worked properly since the system reset and rewiring, or have you noticed any other quirks?

The telematics repair on my S4 was completed at 95 Euro, which covered fixing a faulty cable connection in the emergency call system. After addressing the wiring issue and performing a system reset, the SOS signal has worked flawlessly with no recurring problems. The diagnostic codes helped pinpoint the exact connection that needed attention, making it a straightforward fix for a qualified technician. The car safety features are now functioning exactly as intended, with no warning lights or error messages in the instrument cluster. Looking back, having a proper diagnostic assessment was crucial for identifying the specific wiring issue rather than replacing unnecessary components. The repair has proven reliable, no quirks or issues have surfaced in the months since the fix. The emergency call system now performs its standard self-checks without generating any fault codes or warnings.

Thanks everyone for the input on my emergency call system malfunction situation. Finally got it sorted last week and wanted to share my experience. Took it to a certified shop specializing in automotive electronics. The diagnostic codes confirmed a damaged wiring connector at the control module, exactly as suggested. Total repair came to 850 Euro including labor, parts and system programming. The technician found some additional corrosion near the main harness that could have caused future problems. Good thing I got it checked when I did. They cleaned the connections and applied protective coating while doing the repair. The SOS signal is working perfectly now, no more warning lights or error messages in the cluster. The shop ran full system tests after the fix to verify everything was communicating properly. Really relieved to have this safety feature functioning correctly again. My only regret was not addressing this malfunction sooner instead of trying basic resets. Lesson learned about not delaying repairs involving safety systems. Thanks again for steering me in the right direction.
