VW Touran GPS Signal Loss After Mechanic Visit

Having experienced similar GPS signal interference on my 2020 VW Tiguan, I can relate to this navigation system problem. The symptoms you describe match exactly what happened in my case, complete signal loss and error codes. The root cause turned out to be a damaged GPS antenna connection under the rear roof section. During a previous sunroof maintenance, technicians had accidentally pinched the antenna cables, creating intermittent signal issues that eventually led to complete failure. The repair required: Full diagnostic scan of the car navigation system, Removal of headliner to access the GPS module, Replacement of the main GPS antenna assembly, Recalibration of the navigation system This was not a quick fix and required specialized diagnostic equipment. The GPS module itself was fine, but the antenna repair was essential for proper function. The work took about 4 hours in total, and it needed to be done at a certified service center with proper diagnostic capabilities. Since the repair, the navigation system has worked flawlessly. Would strongly recommend having a certified VW technician properly diagnose the issue, as incorrect repairs can lead to more expensive problems later.

Thanks for sharing your Tiguan story, really helpful to hear about the pinched antenna cables causing similar GPS signal issues to mine. Did you find it solved everything completely? Just wondering what the total repair cost came to for the car electronics work and antenna replacement? Also curious if any other issues popped up after getting it fixed? Mine is booked in next week but want to know what to expect cost-wise for the satellite connection repair. Still have that nagging worry that the GPS module might be the culprit rather than just the antenna.

Since having my Tiguan GPS antenna fixed at the certified service center, the navigation system has performed perfectly. The satellite connection and signal strength are now consistently strong, ending all the frustrating reception problems I experienced before. The total repair cost came to 200€ for diagnosing and fixing the defective GPS antenna, which was actually less than I initially feared. No additional issues have surfaced with the car electronics or navigation system in the months since the repair. The vehicle GPS now acquires signals quickly and maintains a stable connection throughout my drives. Based on my experience, the problem is more commonly related to antenna issues rather than the GPS module itself. The diagnostic equipment at the service center can pinpoint exactly where the fault lies, so you will not end up replacing parts unnecessarily. Getting it properly diagnosed and repaired at a certified center is definitely worth the investment to restore full navigation functionality.

Wanted to update on my GPS navigation issue, took it to a certified VW service center last week and got everything sorted. The diagnostic scan revealed it was indeed a damaged GPS antenna, not the module itself. Turns out some recent work on the roof rack had actually cracked the antenna housing, letting moisture get in and corrode the connections. The repair involved replacing the entire GPS antenna assembly and reconnecting all the navigation system wiring properly. Total cost came to 280€ including the diagnostic work and new parts. Shop had it done in about 3 hours. Navigation system is now working perfectly, picks up satellite signals right away and holds a strong connection throughout my drives. Really glad I went to a proper service center this time instead of risking another questionable repair job. The vehicle GPS is back to full functionality and the peace of mind was worth the extra cost. No more error codes or lost signals to deal with.
