VW Eos Power Seat Failure, Motor/Harness Issue Fix

I had almost the exact same issue with my VW Golf GTI from 2010 about a year ago. My experience with car repairs is moderate, I can handle basic maintenance but leave the complex stuff to professionals. The power seats completely stopped working on the passenger side, similar to your situation. After checking the fuses like you did, I took it to my regular workshop. The seat adjustment controls were completely unresponsive, just as you described. Turned out the battery had discharged so heavily it affected the seat control module. The workshop performed a full system diagnosis and found that the prolonged low voltage had damaged the seat wiring connections. They had to: Test the seat switch functionality, Replace damaged wiring in the seat harness, Recalibrate the power seat system, Install a new battery Total cost was 290€ for parts and labor. The repair took about 3 hours. To help diagnose your specific case better: What year is your Eos? Does the driver seat still work normally? Have you noticed any other electrical issues? When did the problem first start? This could be more than just the seat motor if its similar to what I experienced. A proper diagnosis would show if its the seat wiring, control module, or the battery causing the issue.

Last service was done at 75000km. Thank you for sharing your experience with the electrical seat issue. You mentioned checking seat wiring, my mechanic took a look and he found the automotive seat harness was actually damaged from repeated movement over time, not a battery issue in my case. The electric seat motor itself tested fine after replacing the wiring. The repair worked out cheaper than expected, just 180€ for parts and labor since it only needed new seat wiring harness and no replacement of the actual car seats or motors. The seat switch and controls are now working perfectly again. Perhaps this information helps others diagnose similar power seat problems in their vehicles. Always worth checking the basic wiring before assuming a more expensive component has failed.

Thanks for the update on your Eos seat repair. Good to hear you got it fixed for less than my repair cost. The seat harness damage from regular movement is actually pretty common, I wish I had checked that first on my Golf GTI before going through the whole battery replacement. Since both our cases involved seat harness wiring issues, its worth mentioning to others that the repeated movement of power seats can eventually wear through the wiring insulation. The seat adjustment mechanisms put constant stress on these cables every time the seat moves forward or back. The 180€ repair cost sounds about right for a seat harness replacement. Much better than having to replace the entire seat motor or power seat assembly. Your mechanic was smart to test the motor functionality after fixing the wiring, saves replacing parts that dont need replacing. Maintaining working power seats definitely improves the daily driving experience. After my repair, I started occasionally checking under the seat for any visible wire wear during regular maintenance.

Great that my mechanic found the real issue with the automotive seat harness. The wire damage from movement makes total sense, those cables flex every time the power seats adjust. Much better paying 180€ for new wiring than replacing the whole electric seat system unnecessarily. The seat motor testing fine was a relief. Once the new seat harness was installed, all the seat switch functions started working perfectly again. No more issues with any of the power seat adjustments. Worth mentioning to others facing similar electric seat problems, getting a proper diagnosis of the wiring first can save replacing expensive parts that might actually be working fine. My repair cost was reasonable since we only needed to fix the worn cables under the seat. Thanks again for sharing your similar experience. Even though your case involved battery issues, the damaged seat wiring seems to be a common problem in power seat systems. Regular checks of the cables during maintenance could help catch wear before complete failure.
