VW Lupo Seat Massage System Failure Fix Needed

Having encountered this exact seat motor issue on my 2007 VW Polo TDI, I can share some relevant insight. The massage seat function typically fails due to two common problems: a faulty connection in the wiring harness under the seat or a worn-out switch module. When my luxury car features started acting up, the seat control module displayed similar error codes. The main culprit was a damaged wire bundle where it flexes near the seat frame. The constant movement had caused the insulation to wear through, creating intermittent connections. The repair process involved: Testing the seat motor functionality, Inspecting wire harness connections, Checking switch assembly continuity, Replacing damaged sections of the wiring loom This turned out to be a moderate repair job, requiring specialized diagnostic equipment to properly address the massage chair system. While not a critical safety issue, leaving it unrepaired can lead to additional electrical problems throughout the seat control network. Consider having a professional workshop with experience in automotive electrical systems examine the switch failure. They should perform a full diagnostic scan to pinpoint whether its a wiring issue or control module problem.

Thanks for this detailed response about the massage seat issue. The diagnosis seems spot-on as my fault codes match what you described. After taking it to the shop and having them look at the car upholstery and wiring, the seat switch was definitely worn through near the frame, just like you mentioned. Do you remember approximately how much the repair ended up costing you? Also curious if youve had any related electrical issues with the luxury car features since getting it fixed? My mechanic mentioned something about potential module problems down the line, so Id appreciate knowing if anything else came up for you.

After getting my VW checked out by the mechanic, the massage seat switch problem was completely resolved. The repair involved fixing a faulty cable connection near the seat motor, exactly where the wiring meets the frame. Total cost came to 95€, which included the diagnostic scan and repair work. Since the fix, all the luxury car features have worked perfectly with no additional electrical issues. The car upholstery and massage settings function just like new, and the error codes haven't returned. This suggests the mechanic correctly identified the root cause being the worn cable rather than a larger module problem. The repair has proven to be reliable and cost-effective compared to replacing the entire seat motor or control module. The initial diagnosis of a wiring harness issue was spot-on, and I havent experienced any related electrical problems in the months since the repair.

Today I finally got the massage seat issue resolved at the repair shop. The mechanic found exactly what was suggested, a worn-out wire harness near the seat frame connection. The total repair came to 280€, which included a full diagnostic scan, parts, and labor. More than expected, but less than replacing the entire seat switch system. The car upholstery had to be partially removed to access the wiring, but they did a clean job putting everything back together. All luxury car features are now working perfectly, the massage settings respond immediately and the error codes have cleared from the computer. Still monitoring for any recurring issues, but the repair seems solid. The mechanic mentioned they reinforced the wire bundle where it flexes to prevent future wear. Much better outcome than my previous repair experience, and I appreciate the guidance from this forum in identifying the likely cause before taking it in. Looking forward to fully enjoying my massage seat function again after months of dealing with this switch failure. Time will tell if this fix holds up, but so far everything is working as it should.
