Hi Charlie, Thanks for your reply, I got the car after it had stood for 18 months, I had to fit a new exhaust system including the dpf, It starts and run's very well
and has no other issues besides this smoke problem,
When first started it run's ok and tickover is around 800 revs, on driving the car it runs well but sometimes it starts to smoke as if from excess fuel and the tick over is around 1000 revs, I had it checked out by our local garage who could not find any fault or codes to explain this and no fault codes come up on the dash,
Ive just changed the air mass sensor but its no difference to the problem,
This smoke problem is random as I have driven the car hard and also driven it carefully but it seems to be random as though something is sticking, If you turn the engine off for a short while then restart , the tickover returns to around800 revs and the smoke clears,
Any ideas would be welcomed, Cheers Mike,
