Hi,

Our 2008 A4 Convertible Quattro passenger seat does not move forward/back. Pulled the motor out and tested it. The motor works fine. I had to run separate wiring from the battery to it (once replaced) to move the seat far enough forward to remove the rear bolts.

I would think it is the main switch on the seat or relay block. I hear a relay click in one direction but not the other. It has the rear seat assist button on the top of the seat, maybe it is the connection of this to the switch seat?

I was hoping someone might have scans of the electrical diagrams showing the seat and I could try some tests before trying buying the seat button module or relay box.

All other seat functions work well. Just forward/reverse doesn't work.

Update

I was able to jumper the fwd/back motor and get the passenger seat out. While i'm waiting for my Bentley book to get the electrical schematic, I checked the switch with a meter and all contacts seem to work (took some doing like a game). I still ordered a new switch.

I am now thinking it is the control module under the seat. I will try a used one first. $70 vs $340 is worth the try. My wife is really to want to drive the car but I don't want to pull the seat in and out several times.

It would seem the switch on the top of the seat back could be an issue too. I will look at it after the control module if that does not fix it.
