The relay should only allow the seats to be adjusted when the door is open or the key is set to ON.

If the seats do not move when the key is set to ON, you may have to test and replace that relay.

Please check to see if the passenger side seat suffers the same problem.

Note: Edited to reflect that the car only has one seat relay that controls both passenger and driver's side seats.

I always thought that my seats adjusted at all times.
Thought everyone else had problems!

My post on 5/24/08:
In my '04 coupe, my seat operates if the ignition is on and the doors are closed, but it does not work if the ignition is off and the doors are closed. But, it does work if the ignition is off and the driver’s door is open? I don't get the German logic on this one??

Response from member Hangman on 5/24/08:
It does make absolute sense. There are two pockets behind the seat that can be used to hold things (flat things). If you have the top open and the car locked, you don't want someone to be able to just reach in and move the seat forward and grab whats in those pockets. Thats why you can only move the seats with the door open (meaning you have the key to unlock the door) or with the ignition on and the doors closed. Similar to the reason why they made the central locking button deactivated once the engine is turned off, so that it prevents someone from reaching in and unlock the doors and alarm when you park with the top down.

I'd say the relay has a diode failure in the relay. My seats only operated with the doors open and the ignition on or off. I replaced one of the two diodes, 10 cents each, and they now work as stated above. I always wondered what the other diode affected and now I may know.
