Audi A3 Emergency Call System Failure Warning Alert

Had the same telematics issue on my 2014 Audi A4 2.0 TFSI. The automotive electronics showed identical symptoms with emergency call system warnings and call failure alerts on the dash. The root cause was a damaged wiring harness connector at the telematics control module. Over time, vibration and heat cycles caused the pins to develop poor contact. The diagnostic codes initially suggested a complete module failure, but the actual fix required cleaning the connector pins and replacing a section of the wiring harness. This is not a critical safety issue but needs attention since the emergency call function is a mandatory system in many regions. The repair involves removing several trim pieces to access the module located behind the dash. A proper fix requires specialized diagnostic tools to verify the telematics system is communicating correctly after repair. Recommend having this checked by a shop with Audi-specific diagnostic equipment, as generic scanners often misinterpret these types of connection faults. The repair is straightforward for experienced technicians who know where to look.

Thanks for sharing your experience with the wiring harness problem. I had similar telematics warnings on my A3 last year and initially feared a complete SOS system failure. The car safety systems were fine, but the emergency call feature kept showing malfunction alerts. Could you remember roughly what you paid for the repair? My fix included a new wiring section plus labor, but I am curious how costs compare. Also, has everything been working properly since the repair, or have you noticed any other warning messages pop up?

Following my visit to the mechanic, I am happy to report the emergency call system malfunction was completely resolved. The repair involved fixing a faulty cable connection at the telematics module, similar to your situation. Total cost came to 95 Euro, which covered both the connector replacement and labor. Since the system reset and repair six months ago, all warning messages have disappeared and the emergency call function works flawlessly. No additional call failure alerts or telematics issues have surfaced. The repair shop identified the exact connection problem quickly, which kept the costs reasonable compared to replacing the entire module. The key was finding a technician who knew exactly where to check for these specific connection issues rather than jumping to replace expensive components. Regular vibration from driving had simply worn down the original connection point.

The fix worked out great in the end. Took my A3 to a specialist who diagnosed the control module wiring issue right away. They spotted the worn connection causing the call failure warnings without trying to sell me unnecessary parts. Total repair came to 180 Euro, bit more than yours since they had to replace a larger section of the harness. The system reset cleared all the warning lights and the emergency call function tests perfectly now. Three months in and no more telematics issues or malfunction alerts. Really glad I asked here first and learned about the wiring problem. Saved me from potentially overpaying at shops that might have pushed for complete module replacement. The automotive electronics in these cars can be tricky, but finding the right mechanic who knows what to look for makes all the difference.
