VW Up Window Controls Dead, All 4 Windows Frozen

I had a similar issue with my 2018 VW e-Golf. As someone with moderate experience in car electronics and diagnostic work, I initially thought it was related to the window controls themselves. The complete failure of all power window functions turned out to be linked to a weak vehicle battery. After the battery replacement for 290€, the window system required a reset procedure to initialize the window regulators properly. The car electronics needed this reset because the power interruption caused the window control module to lose its calibration settings. The reset process for the window controls was straightforward: 1. Start the car 2. Press and hold window switch down until fully open 3. Release switch 4. Pull switch up until window fully closes 5. Hold switch up for 2 more seconds 6. Repeat for each window Before suggesting specific solutions for your case, could you share: Have you noticed any other electrical issues? Does your battery warning light show on the dash? Are other electrical functions working normally? Have you attempted any window reset procedures? This information would help determine if your Up is experiencing the same battery-related window control issue or if there might be different underlying problems with the window switch system.

Thanks for sharing your experience. Our cases sound quite similar, my Up has 104080km and was last serviced 3 months ago. I checked the battery voltage and found it at 11.2V, significantly below normal. This could explain why all window motors stopped working simultaneously. Your reset procedure might be exactly what I need after fixing the battery issue. There are other minor electrical quirks happening too, the radio occasionally restarts and the central locking sometimes needs multiple clicks to work. These symptoms align with your battery-related diagnosis. I will try getting the battery replaced first, then follow your window control reset steps. Will update on whether this resolves the power window problems.

The battery voltage reading of 11.2V definitely confirms our suspicion. After dealing with the exact same issue in my e-Golf, I learned that modern car electronics are quite sensitive to voltage fluctuations, especially window control systems. The radio restarts and central locking issues you mentioned are classic signs of a weak battery affecting the car's electrical network. When I replaced my battery, those minor electrical quirks disappeared along with the window troubles. Just a heads up based on my experience: After installing the new battery, you might need to attempt the window reset procedure multiple times for each window. Sometimes the window troubleshooting process requires patience, as the control module needs time to relearn proper positioning. Make sure to complete the full reset sequence without interruption. Also, while replacing the battery will likely solve the issue, it might be worth having the alternator checked during service. A faulty alternator could cause premature battery drain and lead to similar window control problems down the line. Would recommend documenting any error codes before clearing them after the battery replacement. This helps track if new issues emerge that arent related to the power supply.

Thanks again for confirming these details. After reviewing the battery voltage and comparing our similar electrical symptoms, I feel much more confident about the repair path. I just ordered a new battery that should arrive tomorrow. Good point about trying the window regulator reset procedure multiple times, I will make sure to be patient with the initialization process for each window. The radio and central locking quirks really do point to this being primarily a voltage issue rather than needing a complete window control system replacement. I took your advice and wrote down all the current error codes before proceeding with any repairs. The auto parts store quoted 260€ for the battery, which seems reasonable given the specialized battery type needed for electric vehicles. And yes, I will definitely have them check the alternator charging system while doing the replacement to prevent future window troubleshooting headaches. Will start with the battery swap and window reset sequence you outlined. The systematic way you explained the power window reset procedure should help me get all four windows working properly again. Thanks for helping me avoid what could have been a much more expensive repair.
