    Hi

    I need help my Audi A6 (2003) 2.5 TDI model has developed a fault in that when it is in idle or low speed it is missing/rattling (juddering) the problem seems to be getting worse by the day and is very worrying.

    When I accelerate above 40mph the ride becomes smooth. Which leads me to beleive that I may have a faulty injector.

    I have taken it to a local mechanic and he stated that the cam belt may be at fault but after checking that.. it is clear to see that is not the problem.

    I think it has something to do with the fuel delivery but I am not knowledgable on cars so would appreciate if someone can help as it is not sounding healthy at all.

    Has anyone else had a similar problem and please can someone help before I fork out a fortune for someone to diagnose it!

    thanks
