GazHyde published a new article:

This article will show you how to manually move your seats forwards if the back/forwards motor has failed.

It's all too common that either the seat motor fails, or that the seat jams in the rails because it has been adjusted too far back. Using this procedure you can move the seat forwards...

Nice write up Gary, for reference the motors are interchangeable albeit the colour codes are different.

This is a pair of motors. Can anyone identify which is the forwards/backwards and the up/down one?

I think the longer cabled one is the front/back motor

Forwards/Backwards = Right
Up/Down = Left

Notice the coloured connectors on the end of the looms, black and white, these match up with seat loom.

I believe motor on the right is the front/back on
Looks like we have a consensus of three then. I'll update the image in a bit.

My drivers seat forward/back motor is pretty noisy. Not sure if it's the motor or another part. Anybody have experience of noisy motors failing?

@DivideBYZero If you look at gary's picture in the first post there are two drive spindles coming out of the motor, these drive spindles are enclosed by a plastic tube. I bet one if not two of the spindles are slightly bent and are rubbing against the plastic tube which causes a loud noise. To test this put your hand over the tube/s and move the seat backwards/forwards you will feel if they are bent. You can straigten them again without removing them from the car.
