Hello have a lie down there! at my opel omega b caravan 2.0 16v xe20xev have removed the suction tube and sent away to have valves glued in by vialle for my gas system. the suction tube is inside again. empty run controller and DK unit were cleaned with special cleaner. so now to my problem… I have reassembled everything and should start the car when I noticed that the plug from the DKpoti was switched to the one from the nw sensor. I have the complete cable ba in order to get rid of everything in order to solder and install everything properly and not to make sure that the plug of the poti and nws are the same and now I have the mallör! error codes were following nwsensor signal faulty and DK sensor voltage too low fc was read out with a tech2 so then I renewed the poti further today I renewed the nwsensor (siemens) and still the same problem! earlier I drove there was strangely the MKL off and no error code available. I turned off the car and restarted zack the fc was back inside! what now ?
