The car Audi a3 2.0tdi 170 2007 dsg. 74000 with full audi service history Ive had the car just shy of 2 weeks. Since owning the car ive had an oil service (longlife), cambelt/waterpump and dsg oil change. Now when cold it wont start on first crank only on 2nd attempt. Its fine when its warm still pulls well, no smoke etc. Now it may be me but i am sure this problem occured since i had the first job carried out which was th engine oil change? Is beggining to worry me somewhat now as it took me along time to save up for this car, and had always been my dream car.
