Hi, first post to forum and would appreciate any help. The car starts from cold with white smoke from the exhaust which clears soon after. On a run and when warm it will smoke generally at junctions and when pulling away. Noticed the fuel consumption at tick-over is around 17mpg but am sure it used to be nearer 27mpg. The car is a 2001 and I have owned it for 6 years, mileage is 51,000. Had it scanned and it showed a fault with the air flow meter which was replaced. On a drive after it seemed perfect but then after 5 miles it started again. The smell from the exhaust is different. Never had any water or oil loss and no overheating. Help needed Chris b.
