I wonder if any of you can help me. I have recently brought a 2.0GL galaxy N reg and enjoying the car, but with a few niggily faults. My drivers door keeps coming ajar which is very annoying and could be dangerous. I have had the lock tightened up but it has started again. Before I go to the mechanics is there anything I can do. Also there is a smell of fumes that comes into car. I have had the dreaded MAF sensor replaced which I thought had cured it, but again it has started again. The curious bit is that when we went on holiday down the West country the door didnt fly open and the car didnt smell. Many thanks Robin
