VW Up Electrical Failures After Dealer Service Visit

I experienced similar electrical system issues with my 2015 VW Polo TSI. The symptoms matched exactly, navigation malfunction and general electrical glitches. A diagnostic check revealed the car was indeed in transport mode, which commonly occurs after battery disconnection or certain service procedures. The fix required a proper automotive software update and car configuration reset at a specialized workshop. The transport mode issue affects multiple control units, causing various electrical components to behave erratically. This was a serious technical issue that needed professional intervention with specific diagnostic tools. Rather than returning to the dealership, an independent workshop specializing in car electronics managed to resolve the problem. The key was having access to the correct diagnostic equipment and latest software versions. Before paying for any repairs, recommend having these specific checks: Full system diagnostic scan, Battery health assessment, Control module configuration verification, Transport mode status check The electrical problems completely resolved after the proper diagnostic check and system reconfiguration. This is not something that typically fixes itself or can be resolved with basic tools.

Thanks for the detailed response about your Polo issues. I had almost identical problems with my Up last year, unusual electrical failures and a completely dead navigation system. The specialized workshop also found my car stuck in transport mode and the immobilizer system was affected too. Did you track what you paid for the full fix? My repair bill seemed steep but at least all the electrical gremlins disappeared after the software update and diagnostic check. Just wondering if the cost was similar and if youve had any recurring issues since the repair was done?

Had the transport mode active issue fixed last week actually. Like your Up, my Polo needed a complete vehicle setting reset and software update to get everything working properly again. The car electronics went back to normal after the workshop sorted it. Since my car was still under warranty, the engine start system and electrical fixes cost nothing. No recurring issues at all, the navigation works perfectly and those unusual electrical glitches completely stopped after the automotive diagnostic work. The key was finding a workshop with the right diagnostic equipment to properly reset the transport mode. Once they corrected the control unit settings, everything went back to working like new. Based on how smoothly mine runs now, looks like we both made the right call getting professional help for this specific technical problem.

Finally got everything sorted with my Up after visiting a specialized workshop. The whole ordeal cost me 450€, which included a full diagnostic check and software updates to fix the transport mode issue. The technician explained they had to reconfigure multiple control modules and reset the entire electrical system. After two full days in the shop, my car is running perfectly again. The navigation works, no more unusual electrical failures, and the engine start is smooth every time. Much better experience than my previous attempts at the dealership. Looking back, wish I had gone straight to this automotive specialist rather than wasting time elsewhere. For anyone facing similar issues, getting a proper diagnostic check from a workshop that knows these electrical problems is definitely worth it.
