VW Touran Warning Lights Signal Safety System Issue

I had a similar issue with my 2019 VW Tiguan last year, and having some experience with VW electrical systems, I can share what worked for me. The symptoms were nearly identical, multiple warning lights and error messages related to safety systems. The telematics control module was showing faults, affecting the SOS signal functionality. Initially, I tried a basic system reset by disconnecting the battery for 30 minutes, but the warnings returned. Took it to my regular workshop where they diagnosed a faulty wiring connection to the emergency call module. The repair involved replacing damaged connector pins and securing the cable harness properly. Total cost was 95€ including diagnostic time and parts. The fix has been reliable with no recurring issues since then. These problems often stem from loose or corroded connections rather than complete module failure. To provide more specific advice for your case, could you share: Are there specific error messages displayed? Does the SOS button respond when pressed? Have you noticed any water damage or previous repairs in that area? Did the issues start suddenly or develop gradually? These details would help determine if your situation matches what I experienced or might be something different.

After getting multiple suggestions, I did a complete diagnosis at my trusted workshop. Since my car has 120004km on the clock, they suggested checking all connections first. The automotive electronics specialist confirmed a failed communication module causing the car safety alerts. They performed a thorough system reset after replacing the defective unit. The SOS signal is now working properly and all warning lights have cleared. Total repair cost was 450€ including parts and labor. Been driving for 2 weeks now without any warning messages reappearing. Thanks for the helpful suggestions about checking connections first, saved some diagnostic time. For anyone facing similar symptoms, make sure they check both the physical connections and the module itself. Sometimes it is not just a simple wiring issue.

Thanks for the update on your repair experience. Your case actually aligns perfectly with what I encountered on my Tiguan, though yours needed a more extensive fix with the full module replacement. The high mileage factor often reveals these kinds of control module issues, and it is good you went straight for a professional diagnosis. While my connection repair was sufficient, complete module failure is common in these systems after extended use. The 450€ repair cost seems reasonable considering the replacement part and programming work involved. These car safety components require precise calibration after installation to ensure proper emergency call system function. The successful repair confirms what I learned from my similar experience, when multiple system warnings appear simultaneously, the root cause often traces back to the communications module rather than individual system failures. Keep monitoring the system reset status for a few more weeks, but based on my experience, once properly fixed, these repairs tend to be lasting solutions.

Wanted to provide a final update after 2 months of driving: The new control module continues working flawlessly. No warning lights or system errors have returned. The diagnostic codes remain clear and the emergency call function tests positive every time. For the workshop cost breakdown: Module unit: 290€, Programming and calibration: 120€, Diagnostic time: 40€ Looking back, going directly to a workshop that specializes in automotive electronics was the right choice. The system reset and module replacement fixed all issues in one go. Important learning: When multiple car safety alerts trigger together, checking the central communication systems first can save time and money. Appreciate all the helpful responses that guided me toward the correct diagnosis path. The repair solutions shared here matched my final fix perfectly. Having this documented might help others facing similar warning light combinations in their vehicles.
