850's? Bmw 850's that is... I've got one today thats driving me ..
Had the whole dash ripped apart, the ekm out and apart, checked everything i can check short of condemning the ekm.
No gauges work at all, no speedo,tach ,fuel ,temp, everthing else on the dash works fine, the Mid doesn't work either at all... Mid is the 850 equivalent of the obc..., Checked both batteries, load tested and replaced since i've seen weird things on 850's if the batteries aren't perfect...
