Seat back motor fixed. Recaro. S3
For all those with recaro's and maybe your seat back motor is not working on S3 then maybe read on:
After stripping the seat out and apart i found a connector from the circuit board to the motor hidden in the seat frame at the bottom. This had come un-done. The harness from the curcuit board does not go strait to the seat back motor but to bottom of seat frame, then a second lead up into rear of seat to motor.
Was in the end a simple fix.
I shall post this for anybody in future doing a search and solve without completely stipping like me(!)
