I've just bought a 2005 TDI avant s-line (140bph) starting to have problems already 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
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
