Audi Emergency Call System Failure Causes & Fixes

Having some experience with Audi vehicles, I encountered a similar telematics issue on my 2015 Audi A3. The diagnostic codes pointed to a call failure in the emergency communication system, which turned out to be caused by loose connections. The automotive electronics showed multiple warning lights, exactly like your situation. After checking with my workshop, they found a faulty wiring connection between the control module and the emergency call system components. The malfunction was resolved by replacing the damaged connector and ensuring proper cable routing. The total repair cost was 95 Euro, covering both diagnostic work and the connector replacement. It was a relatively straightforward fix once they identified the root cause. To provide more specific guidance for your case, could you share: Have you noticed any pattern when the warning lights appear? Did you recently have any work done near the control modules? Are there any specific error codes stored in the system? Does your vehicle have any aftermarket modifications? This additional information would help determine if your issue matches the common failure pattern I experienced.

Thanks for sharing your experience. My A4 currently has 183145 KM and had its last service 2 months ago. After reading your reply, I checked the system error logs using a basic OBD scanner, but no additional error codes appeared beyond the emergency call system malfunction. The warning lights are constantly on, not intermittent, which makes me think this could be a more serious control module issue rather than just loose wiring. The car safety systems all seem to work normally despite the warnings. No modifications have been done to the telematics or electrical systems. I might try a system reset before taking it to a specialist, though Im concerned this could be a module failure requiring replacement.

Thanks for those additional details about your A4. Based on the constant warning lights and the symptoms you described, my situation turned out differently than I initially suspected with my A3. After my first attempt with the wiring fix, the telematics error actually returned a few weeks later. The system reset I tried didnt resolve the issue permanently. It ended up being a faulty control module that needed complete replacement. The constant nature of your warning lights matches what I experienced in the second phase. The module replacement cost was significantly higher at 890 Euro, but it permanently resolved the SOS signal malfunction and cleared all associated warning lights. A simple reset might provide temporary relief, but given your cars mileage and the persistent nature of the warnings, I suspect youre looking at a similar control module replacement scenario. The good news is that once replaced, the emergency call system should function perfectly again. Consider having a specialized diagnostic performed before attempting any fixes. This will confirm if your situation matches the control module failure pattern rather than a simple wiring issue.

Thanks for all the detailed information. I really appreciate your candid feedback about how your similar issue turned out differently than expected. After weighing the options, I decided to take my A4 to a specialist automotive electronics shop for proper diagnosis before attempting any fixes myself. The constant warning lights and emergency call system malfunction definitely match the symptoms you described with your failed control module. While I was hoping for a simple wiring fix like your initial 95 Euro repair, Im now mentally prepared it could require the full module replacement closer to 890 Euro given the similarities to your situation. Ill pass on attempting the system reset for now since it only provided temporary relief in your case. Better to get it properly diagnosed and fixed right the first time, especially since the SOS signal and car safety systems are involved. I appreciate you sharing both your initial repair attempt and how it ultimately needed the more extensive fix. It helped set realistic expectations for what Im likely facing with my vehicle.
