VW Sharan Power Seat Failure: Motor & Wiring Solutions

Last month I had a similar issue with the passenger seat in my 2010 VW Touran 2.0 TDI. The seat motor completely stopped responding, and the warning light appeared just like in your case. The problem turned out to be more serious than expected. After diagnosis, we found corroded wiring connectors under the seat that were causing intermittent power supply to the seat motor. The moisture from a small leak in the floor pan had slowly damaged the electrical connections. The repair required: Complete removal of the passenger seat, Replacement of the main seat wiring harness, Installation of new seat motor connectors, Cleaning and treating the floor pan area, Resetting the error codes The entire job took about 4 hours at the shop. Most automotive seat wiring issues like this need professional attention since accessing the components requires special tools and proper reconnection is critical for safety systems to work correctly. Based on your vehicle age and mileage, I would suspect similar wiring degradation rather than a failed seat switch or motor. Have a certified mechanic check the connectors first before replacing any major components.

Thanks for sharing your experience with the seat motor issue. I also had that problem with my Sharan last summer. Wondering if you remember roughly how much you paid for the full repair? Mine is acting up again with similar symptoms, and I want to compare costs before heading to the shop. Also, has the seat adjustment been working fine since the repair, or have you noticed any other electrical gremlins with the passenger seat?

Since the repair of my power seats last month, everything has worked perfectly with no recurring issues. The passenger seat moves smoothly in all directions, which is a huge relief after dealing with the complete failure. The total bill came to 290€, which covered diagnosing and fixing a heavily discharged battery that was causing the seat motor problems. This was actually much less expensive than I initially feared, especially compared to replacing the entire seat harness like I thought might be needed. My experience shows that automotive seat electrical issues aren't always as complex as they seem. Sometimes basic electrical system problems can cause the power seats to malfunction. Having a proper diagnosis by a qualified mechanic really helped avoid unnecessary parts replacement. If your symptoms are similar to what I experienced, I'd recommend getting it checked soon. Leaving electrical issues unaddressed can sometimes lead to more expensive repairs down the line.

Thanks for all the replies. I took my Sharan to the mechanic last week to get the seat adjustment issue sorted. The electric seat had completely stopped responding, and I was worried it would be an expensive fix like a full seat motor replacement. Turns out the main issue was actually corroded terminals in the seat wiring harness. The mechanic found water damage from a sunroof drain leak that had been dripping onto the electrical connections. They cleaned all the contacts, replaced a section of damaged seat wiring, and applied protective coating to prevent future corrosion. Total cost came to 220€ for parts and labor, which was better than expected. The seat switch and adjustment functions are now working perfectly after the repair. Really glad I got it checked out before the problem got worse. Will definitely keep an eye on any water leaks in the future since they mentioned this is a common cause of seat electrical problems in these cars. The whole repair took about 3 hours and saved me from potentially bigger issues down the road.
