Sorry I forgot who posted, but someone with a 90 model e34 has had mpg and
range problems with the obc.
Check the gas gauge, does it show readings between full and 1/2 or go to half
very quickly?
Cars produced 6/90 to 2/91 had a non linear gas gauge that must be corrected
by a software download from the dealer. US service bulletin 62 02 91 (3237).
If you think this might be the problem, let me know and i will share more
details.
