hi all, i have a bmw that came in with temp gauge in the red, no dme communiction with diagnostic machine, engine swings but won't fire up, done all the checks for power supply and earth to the dme. bought a 2nd hand dme and removed the 28f800 flash from original box and fitted to the 2nd hand box, vehicle doing the same, i then swapped the chips back and now both boxes are doing the same thing, any ideas would be greatly appreciated. thanks. i then bought a new 28f800 and transfered the data, same problem.
