BMW Fly by wire accelerator for an E30 - Win!


A guy I work with was a BMW mechanic and was parting out an E39 vehicle.

It was one of the first with fly by wire.

In a stroke of German luck, the fly by wire accelerator fits the E30 almost perfectly. No need for a clumsy Curtis throttle pot, and a few days work.

If you get one, try and get one from a manual vehicle. Mine is from an auto and has a kick down detent near the end of its travel.

The BMW part number for the auto is 259160-10
See here for explanation of operation.
See here for pinouts

This looks to be the correct assembly from a manual vehicle.

Make sure you get the backing plate that attaches to the floor. The one I have has a tongue that attaches to the plate on the floor. The mounting hole wont quite line up with the stud on the floor so some modification will be required to the backing plate or the mount.
Be sure to get the connector and a good length of wire as well.

I need a 5 pointed security Torx driver to disassemble it and see if I can remove the detent.

Floor fits perfectly. The mounting stud is a little low.
