VW Up Massage Seat Failure After Suspicious Repairs

Had the same electrical issue on my 2018 VW Polo TSI. The seat motor and massage chair functions failed completely after working intermittently for a few weeks. The garage found two problems, a worn seat switch causing connectivity problems and moisture damage to the main control module connector. The repair involved replacing the entire seat switch assembly since individual components are not serviceable. The technician also cleaned and resealed the control module connections. Switch failure is quite common in these systems due to frequent use. This is considered a complex repair since it requires disassembling part of the seat to access the components. The massage function relies on multiple electrical connections working together properly. When one part fails, it can trigger system-wide errors. While not a critical safety issue, leaving it unfixed can lead to more extensive electrical problems over time. Would recommend having it checked at a shop specializing in automotive electrical systems rather than a general mechanic. The diagnostic equipment needed is quite specific for these seat control modules.

Thanks for sharing your experience. The electrical issue with my Up massage controls seems very similar. Really helps to know about the switch failure and control module problems you encountered. How much did the full repair end up costing you? Also curious if you have had any issues with the car upholstery or seat motors since getting it fixed?

After getting the massage seat system repaired, everything has worked perfectly with no further issues. The electrical problem turned out to be much simpler than initially feared, just a loose cable connection to the seat switch that needed proper securing and reconnection. The total repair cost came to 95€, which included diagnostic time and fixing the faulty connection. The automotive seats and upholstery remain in great condition with no signs of wear from the repair work. The massage function now operates smoothly, and the seat switch responds immediately when pressed. The error codes have completely disappeared from the system. Having a specialized technician handle the repair made a big difference. They quickly identified that the issue was just a connection problem rather than a complete switch failure or control module damage as originally suspected. This saved significant costs compared to replacing entire components. Regular use of the massage feature over the past months has confirmed the repair was done properly. The system performs reliably without any electrical issues or error messages recurring.

Thanks for the helpful responses. I took my luxury car to a certified VW specialist who diagnosed the electrical issue quickly. Turned out the seat switch was damaged, causing the massage function to fail. Total repair came to 180€ including parts and labor. They had to remove part of the seat covering to access and replace the faulty components. The technician explained that switch failure is pretty common in these high-end massage seat systems due to regular use. They also found and fixed some loose wiring connections while they were in there. The whole repair took about 2 hours. Really glad I went with a proper electrical specialist rather than my usual mechanic. The massage feature works perfectly now, no more error codes or unresponsive controls. Definitely worth getting it fixed properly to avoid bigger electrical issues down the line.
