Can anyone help a maiden in distress? I have been having a problem with my dear Milly (mercedes c220 cdi). She has been starting on the turn of the key, running briefly then stalling. When I turn her over again it takes ages to start again. This morning was very cold and I started her and had same issue. She started again and was running for 5 mins to warm her. I drove 1/2 mile and she suddenly cut out on me and refused to start at all. I was low on diesel but gauge still showing needle above reserve light. She turns over fine. Had to get her recovered home. I thought might be air in fuel line so tightened the three jubilee clips in the fuel line a week ago but made no difference. Any suggestions warmly welcomed!
