8K0972483 / 4F0972575 Automotive 17-Pin Power Seat Connector — VW / Audi Electric Seat Adjustment
The 8K0972483 and 4F0972575 are 17-pin automotive connectors for VW and Audi electric power seat adjustment control systems. These are the base variants in the 8K0972483 / 4F0972575 connector family — used across Audi A4 (B8), A5, A6 (C6/C7), Q5, and VW Passat B6/B7 for power seat wiring harness connections. The 17-pin configuration accommodates the full circuit complement of a power seat: adjustment motors (fore/aft, recline, height front/rear), position sensors, seat heating, and memory system circuits.
Power seat connector failure is a common issue on VW Group vehicles — the connector sits under the seat and is exposed to moisture from wet clothing, spilled liquids, and floor mat condensation. Terminal corrosion causes intermittent seat adjustment faults, seat memory errors, and seat heating malfunctions that are frequently misdiagnosed as faulty seat motors or control modules.

Why Power Seat Connectors Fail
- Under-seat moisture exposure — the seat connector is located under the seat cushion, directly exposed to spilled liquids, wet clothing, and floor mat condensation; moisture wicks into the unsealed connector and corrodes terminals
- Seat adjustment cycling — repeated seat adjustment causes the wiring harness to flex at the connector entry point, fatiguing wire insulation and eventually causing wire breakage at the terminal crimp
- Corrosion causes motor circuit faults — corroded motor circuit terminals increase resistance, causing the seat control module to detect an overcurrent or open circuit fault and disable the affected adjustment function
- Memory system errors — corroded memory system terminals cause the seat to lose its stored position, fail to recall memory positions, or trigger seat memory warning messages
Frequently Asked Questions
Q: How do I identify which 8K0972483 variant I need?
The suffix letter (base, A, D, F, G) indicates the seat specification level. Check the part number stamped on your original connector housing. If the original is damaged, consult the Audi/VW ETKA parts catalog with your vehicle’s VIN — the catalog identifies the correct connector variant based on your seat equipment level (standard, comfort, sport, massage). Using the wrong variant (e.g., base instead of “D” with heating) will result in missing circuits and non-functional seat functions.
Q: Can a faulty seat connector cause the seat to move on its own or not stop at the correct position?
Yes — a corroded position sensor terminal causes the seat control module to receive incorrect position feedback, resulting in the seat overshooting its target position, moving erratically, or failing to stop at the correct position. This is a safety concern as the seat may move unexpectedly during driving. Inspect the connector for corrosion before replacing the seat control module or position sensors.
Q: Do I need to recode the seat module after replacing the connector?
No recoding is required after connector replacement. However, after replacing the connector and clearing DTCs, perform a seat position calibration by moving the seat to its full forward and full rearward positions — this resets the seat control module’s position reference. For seats with memory function, re-save the preferred seat positions to the memory buttons after calibration.
