Audi A1 Passenger Seat Controls Dead: Fix Needed

Had a similar electric seat problem with my 2018 A3. The power seats completely stopped responding and threw an error code. The issue turned out to be more complex than just a faulty switch. The seat motor diagnosis showed two issues: Corroded wiring harness under the passenger seat, Failed seat control module The repair required: 1. Complete removal of the passenger seat 2. Replacement of the main wiring harness 3. Installation of a new seat control module 4. System recalibration This was a serious repair that took several hours. The automotive seat assembly needed special attention because water had leaked through the floor and caused the corrosion. The seat motor itself was actually fine, but the electrical connections were severely damaged. Worth checking if your power seats have been exposed to any water damage, as this is a common cause of failure in the seat electrical system. The symptoms match what I experienced, complete failure rather than partial function loss typically indicates a wiring or module issue rather than just a motor problem. Make sure to get a proper diagnosis from a qualified shop that specializes in electrical systems. These seat control issues often require specialized diagnostic equipment to properly identify the root cause.

Thanks for sharing your A3 experience. My A1 seems to have the exact same symptoms with the power seats. I finally got it fixed at a different workshop last week. They also found water damage affecting the seat harness connections, which explains why the electric seat controls failed completely. Did you remember roughly how much the repair cost you? I had to pay 780 Euro for parts and labor combined, wondering if that was reasonable. Also curious if youve had any other electrical issues with the seat controls since getting it fixed?

The repair cost on my A3 came to around 290 Euro, which was just for replacing a defective battery that turned out to be the root cause of the seat wiring issues. Much better outcome than expected, since initially the mechanic suspected major problems with the seat motor and control module. The electric seat system has worked flawlessly since the battery replacement six months ago. Unlike your case, we found no actual water damage, the seat switch and wiring were fine once the new battery was installed. The heavily discharged battery was causing electrical system faults that made it appear like a seat control problem. Your 780 Euro repair sounds reasonable considering they had to replace damaged wiring harnesses. Water damage to seat electrical components usually requires more extensive work compared to just swapping a battery like in my case. The key learning was that electric seat problems can sometimes be traced back to the main power source rather than the seat components themselves. Always worth checking the battery first before diving into complex seat wiring repairs.

After getting multiple opinions and feeling frustrated with the first repair attempts, I finally took my A1 to a specialized auto electrical workshop. The thorough diagnosis revealed extensive corrosion in the seat wiring harness just like the others mentioned. The repair process was straightforward but detailed: Located water damage under the passenger seat, Replaced damaged seat wiring sections, Installed new seat switch components, Tested all power seat functions Total cost was 780 Euro, which seemed high at first but makes sense given the complexity of the automotive seat system repair. The power seat controls now work perfectly after 3 weeks of use. No error codes have returned. Big lesson learned, water damage to seat electrical systems needs proper diagnosis by specialists with the right equipment. Regular mechanics often miss these underlying issues. The extra cost for an expert repair shop was worth it to finally get the problem fixed correctly.
