We have bought an Omega b 2.2 Diesel. The previous owner has said that The car does not start. MKL does not glow, The lamp for the preliminary glow goes out even after a few seconds and when you organt he sounds normal. Just doesn’t want to start…. The previous owner had changed the diesel filter and drunk again well. Good for me….. It comes over as if he pulls air. Would like to make it clear again, but I’m not yet so full of diesel. How should I proceed now best.
