    Hi all,

    I've just bought a 2005 TDI avant s-line (140bph) starting to have problems already [​IMG] Hopefully somebody will be able to help.

    The car drives fine when under load. The problem seems to be when driving sensibly then accelerating, theres loads of black smoke out the back and lack of power, if I change down a gear and accelerate then theres no problem. Also today when I started the car it was smoking heavily, I had to gently convince it to rev up. It then ran fine again. Hope this makes sense [​IMG]


    Also, should you be able to feel suction from the pipe connected to the EGR valve? I can blow/suck into the pipe with no resistance.


    Any suggestions would be appreciated. Thanks in advance

    Did you buy the car from a friend or unknown person. Question I ask is........do you know the cars history? Has the DPF been deleted as the car would smoke alot more if it has been deleted. To the untrained eye you wouldn't have a clue it had been deleted if it was done properly.

    Hi,

    I had the EGR valve replaced. Totally solved the problem & runs perfectly now.
    The butterfly at the top of the EGR valve had came lose & was doing what it wanted.

    £230 supplied & fitted.
