RE: Speed sensor
AFAIK both sensors are the same, So maybe get a new sensor and try it on 1 side and see if not swap it over?
Could also be the ABS/ASC ECU which are very common in E39s.

I bought the cheap inpa software for a laptop. It shows the reading from each sensor so I just moved the car and could see my front left was gone.
