try to check the motors, use 12v connections to check it. if the motors didnt work it means the motors is bad.
i've seen that happen to my bimmer friends ALOT
and always one of the motors was the bad

In you trunk under the black plastic cover at the very front is your "convenience relay" It is black and has something like 6 or 8 pins. This is your most likely suspect if both seats are intermittent or inop at the same time.

Is it just the orthopedic function that does not work? If so then if there is a leak then the pump runs on for too long and then codes out and shuts off.

Sounds like your ortho function is blowing a fuse. If your seats work until you use the ortho function, there's your problem.

I had intermittent seat function on my C36, but still had the forward/back. Turns out that the seat adjustment switches had dirty contacts. If you're careful you can slide them out of the door (on the C36 at least), open up the back, and carefully clean the contacts with emory cloth. Now mine work fine and it saved me $50/switch.
