Hi guys hope somebody can help , I've a 54 plate audi 2.5 tdi 180 140000 miles , problems started before Xmas , it struggled to start when left overnight or at workplace so had new plugs put in , it now starts after bout 4 turns or so but when it kicks in it kicks out white smoke ( stinks of diesel ) and sounds rough ( think it's missing and maybe bit tappety ) ita like this for about a min then it's fine and smooth as anything , no loss of power or kicks out any smoke at all , had injectors out , sent to a diesel specialist , they cleaned them all up and they are all in the tolerance or sumthing like that , put them back in and still the same , at a bit of a loss really hope any of you guys can help
Cheers
