    Does "not go up hill" mean literally won't start or maintain any movement on an incline? Blown / shut-down turbo will move, but very sluggishly in a "I really am not sure we can get to the top of the hill" way.

    If you can pull the intercooler hose at the manifold engine is then running on atmospheric pressure which will over fuel engine (ie not enough air for full combustion) and make black smoke. Does it change things?

    I do not have either of these tools. I took off the EGR valve and its caked in soot, i performed the EGR valve test using VCDS and it moved slightly. Ill clean it up and see if it moves more and connect it back to car, see if it has solved the problem

    The car will start, it wouldnt go up hill/an incline what so ever. it will get some movement on a flat but not much.

    Do you mean the intercooler hose that does in the flap valve/EGR valve side? I havent tried that.

    I removed the EGR valve today, cleaned it, put it on the plug and with VCDS i performed the test to see if the valve moved or not. it moved so i dont think its the EGR valve.

    Yes. Try to make sure debris can't get drawn in.

    It sounds worse than I've seen on our car when turbo was not working though. With lots of smoke and that little power I wonder if a piston has popped or something. How does the engine sound?

    might the diesel part filter just need a regeneration as the warning light for that came on before all this problem?

    Just started the car up after a few days of it being parked and their is black smoke from start up. Anyone know if this means it is not likely the turbo?

    I don't think it's turbo. If it was that smokey from something like a bearing - air leak you'd see other symptoms. Air and exhaust are where I'd be looking.

    As an enthusiast who looks after my own vehicles based on mix of hunch, personal analysis and experiences of others I can't be too prescriptive. All I can say is that what you describe sounds more like a fuel / air / exhaust issue than a direct turbo one. EGR and DPF show up in this sort of thing quite often. And injectors plus their seals, etc.
