Hello together At the Omega B of my daughter (98er, X20XEV, hand switch, Limo) a breakdown happened to me today. Actually I just wanted to change the camshaft sensor. The MKL lit up and the cross test referred to the NWS. I changed – everything was fine, MKL. Engine ran clean and a few laps on the yard went successful. Car is not registered yet, so I was not allowed to go to the road. Because everything ran so nicely and I still wanted to screw, I decided, n A Sony, which has at the back interchangeable connections for Dauerplus. These are pluggable cable shoes with an insulating cover above it. Before inserting into the Din shaft everything worked well, after that nothing. So radio out again. One of the two insulating covers had shifted when inserting and a contact was free. It must have come to mass. So from home and in the circuit diagram look which security comes into question. Before that I have the car radio installed. Car still driven to his parking lot. MKL again, no speed indicator, no fan. Hmmmm. The defective fuse was of course found quickly and everything now works as it should. Only the MKL continues to glow. The following errors are stored: 0335 wrong speed signal 0100 voltage LMM too low 1503 immobilizer wrong signal Last error could be related to the fact that I used a key without transponder in advance. and since I only have one transponder, the second key is useless. But that’s exactly what I got. In itself everything works perfectly, only the MKL lights up. What to do? Nice weekend Rolf
