VW Touareg SOS Warning: Emergency Call System Fix

Had the same telematics system malfunction on a 2016 VW Tiguan 2.0T. The SOS error actually points to a loose connection in the emergency call module located behind the overhead console. The fix required removing the headliner to access the module. Found corroded pins in the main connector and damaged wiring from water intrusion through the roof antenna seal. This is a known car safety issue affecting several VW models from that era. A proper system reset alone will not resolve this, the physical connection needs inspection and repair. The damaged wiring harness and connector required replacement to restore emergency call functionality. This repair took about 4 hours of labor since accessing the module is quite involved. If your error persists after cycling the ignition, recommend having a professional diagnose it. Water damage to the module can spread to other automotive electronics if left unchecked. The repair was significant but necessary since the emergency call system is a critical safety feature. Consider checking the roof antenna seal for any signs of deterioration, as this is often the root cause of water entering the module area.

Thanks for sharing your experience. Your description matches my issue exactly. I recently got this same SOS signal error fixed on my 2013 Touareg. The control module was indeed damaged from water getting in through a bad roof seal. Can you remember roughly how much the repair cost in your case? After replacing the wiring and sealing everything up properly, have you had any recurring automotive electronics issues? Just want to make sure I wont face the same problem again after investing in the repair.

Good news, after getting my Tiguan fixed at the shop, the emergency call system malfunction has not returned. The repair was actually less expensive than initially expected, coming in at 95€ to fix the faulty cable connection at the control module. The technician properly sealed all components and verified the telematics system was functioning correctly through multiple diagnostic codes checks. It has been completely stable since the repair, with no warning lights or system errors reappearing. The key was addressing both the wiring issue and ensuring proper weatherproofing around the module. A simple system reset would not have solved this, the physical repair was essential for resolving the root cause. The functionality of the emergency call feature is now fully restored and working as designed. Unlike your Touareg case, my module itself was not water damaged, just the connections needed cleaning and securing. This likely explains the lower repair cost in my situation compared to cases requiring full module replacement.

Finally got this sorted out. Took my Touareg to the repair shop and confirmed it needed a new control module plus wiring work due to water damage. Total repair came to 780€ including labor. More than I hoped but less than I feared. The mechanic showed me the corroded emergency call module and it was pretty bad. They replaced the damaged parts, fixed the roof seal, and ran multiple diagnostic codes to verify everything was working properly. The whole job took about 5 hours. Been two weeks now and all systems are working perfectly, no more warning lights or car safety alerts. The new weatherproofing around the module looks much more robust than the original setup. Good investment to get this fixed properly rather than trying quick fixes that might have led to more extensive automotive electronics problems down the road. For anyone else seeing similar issues, definitely get it checked before water damage spreads to other systems. These emergency call modules are critical safety equipment and worth maintaining properly.
