New to forums so bare with me.
I have inherited a 2.0 TDI 170bhp pd on a 57 plate. It’s done 120kmiles. If you put your foot down it starts to judder and misfire above 2k revs and if you keep your foot down eventually the coil light comes on. Turn the engine off and on and light is gone. Plugged it in with my basic diag tool from amazon and shows p0299 fault turbo charger underboost condition. Lifted engine cover and black crud all over the place. Traced it to the plastic manifold. Googled and apparently common fault and recommended to replace with a BKD aluminium one from Darkside Developments. Ordered and fitted so no more black crud flying out but sadly still no power. I have taken off the turbo actuator as saw somewhere the arm may have seized or unit is leaking causing no boost. Arm feels stiff but never had this issue so have nothing to compare it with to know if it’s broken or not. Before I order one is there anything else anyone can advise? Turbo hoses all seem ok from what I can see.....Help!
