Hello all, Im just wondering what some common problems are with the Motronic system on 745i's and if thier are any reasonable fixes. I had the jetronic in my first Seven and never had any probs with it. But ive heard about some ignition probs with the Motronic and would like to know if i should avoid this car im looking at(an 83 with the motronic) because im told it has a 'hot spot'? and wont start after it warms up...is this commom?thanks all dave nadarski
