Yes Ray I have replaced the sender units with the updated version, no success. When I connected the second hand cluster I had a different fuel gauge reading (maby the reading from the car it came from) when I transfered all the settings from the old to the replacment cluster I ended up with my incorrect reading again. So I must have transfered the fuel gauge calibration into the new cluster. Dont tell me this will happen if I buy a brand new cluster from MB???. How can a brand new cluster be calibrated to the exact ammount of fuel that in the tank?? and why cant it be done to any cluster??
So many questions. I have no problems with BM,s VW,s Audis etc they can all be programed to specs.
