Thanks for responding, it can happen either hot or cold it's very random. It has just had a service so yes has new oil. What do you mean by compression? Engine compression? I have very limited knowledge about cars so have to bare with me, just spent £900 on it on other faults so hoping to avoid another massive bill!

Hi all, I own a 2006 q7 3.0tdi. I have been having starting problems, it cranks over fine but can take up to 10seconds then starts and there is white smoke. I have read on a few forums people with this problem but none have posted whether they found the solution. I have had battery issues in the past but car has a new battery, been fully charged by a garage and still seems to do it so do not think it is a battery issue. If anyone has had this issue and resolved it help would be very much appreciated! Thanks
