VW Up Power Window Failure Hits Both Front Doors

As someone with some hands-on experience in automotive repair, I encountered a similar issue with my 2023 VW e-Golf. The power windows suddenly stopped working on both sides, displaying error codes just like yours. After investigating multiple power window problems, I can share that simultaneous failure often points to the window control module or central switch rather than individual window mechanisms. In my case, the main power window switch was indeed defective and needed replacement. The repair process was straightforward, took about 2 hours at the workshop. Total cost came to 200€ including parts and labor. However, costs can vary based on the specific component that needs replacement. Since your VW Up is from 2021, this should definitely be investigated under warranty coverage. Window control system failures this early are uncommon and could indicate a manufacturing defect. To provide more specific guidance, could you share: The exact error code showing up, Whether the windows make any sound when operating the switches, If all window-related functions (including one-touch) stopped working, Your current mileage, Whether this happened gradually or suddenly This information would help pinpoint whether your issue matches the common power window control module failure pattern seen in some VW models.

Last service completed 2 weeks ago at 79000km, and this fault occurred suddenly after a heavy rain storm. The window regulator makes a faint clicking noise on both sides when attempting operation. Already checked the basic fuses and they appear intact. No gradual warning signs before the complete failure. The error code reads 01603 which matches electrical circuit issues according to my workshop manual. The one-touch function as well as manual operation are both non-functional on all switches. Most concerning is that both windows failed simultaneously despite having independent window mechanisms. Warranty coverage would be ideal considering the vehicle has covered 79439km, though concerned about potential water damage exclusions if moisture is determined to be the root cause.

As promised in my previous reply about my 2023 e-Golf window issues, here is some follow-up based on your additional details. The clicking sound from the window regulator combined with error code 01603 is very similar to what I experienced. However, the timing after heavy rain adds another dimension to consider, water intrusion into the electrical system can trigger these symptoms. In my repair case, moisture had actually entered through a poorly sealed window track and corroded the control module connections. The clicking noise came from the power windows attempting to operate with insufficient power due to the compromised connections. The repair ultimately involved: Drying and cleaning the electrical connections, Replacing the corroded control module, Resealing the window track assembly Total repair time was longer than my initial case, about 4 hours. Final cost reached 350€ due to the additional work needed. Good news: manufacturers typically cover water ingress issues under warranty if they result from design or assembly defects rather than external damage. The simultaneous failure of both window regulators strongly suggests a system-level issue rather than normal wear. Based on the matching symptoms and error code, recommend having the dealer specifically check the control module wiring and seals. This should still fall under warranty despite the water exposure, as these systems are designed to handle normal weather conditions.

Thanks for breaking down the VW e-Golf repair case. The error code 01603 matching my circuit issue is definitely helpful. After getting multiple opinions, decided to bring the car to the dealership since the window regulator issues seem consistent with a known defect. Booked an appointment for next week. The service advisor confirmed they will inspect both the window mechanisms and potential water ingress points. They agreed the simultaneous failure of both door panels likely indicates a systematic fault rather than unusual wear. Will update once I get the full diagnosis, but feeling more confident about warranty coverage after learning about similar cases. Want to avoid any DIY fixes that could void the warranty, especially since the car window system seems to need proper diagnostic equipment to properly assess the electrical faults. Really appreciate everyone sharing their repair experiences and technical knowledge. Having this information helps when discussing the issues with the dealership service team.
