I checked all my intercooler lines again and found nothing so I decided to get to the bottom of it to rule it out a leak. I capped the line off where it enters the intake flap butterfly and at the airbox.
I used the crankcase vent as my vacuum source location. I chose to use vacuum instead of pressure cause the cap I was using at the crankcase vent couldn't pop off then, it would actually help it seal tighter. What I did checked all of the plumbing as well as the intercooler. I turned the pump on and started increasing the vacuum slowly and could only pull 10 in hg with the pump wide open. It should have collapsed the hoses at wide open. I quickly shut the pump off and I could hear a vacuum leak. Now I'm thinking EFF Yeah! Finally! It was the peice of plumbing which attached to the intake side of the turbo. I couldn't find where it was exactly but I just changed the whole pipe with another one I had. Did the same vacuum test and bingo! I it sucked those hoses flat like nothing. So, I hooked everything up and started the car... Same thing, no better whatsoever. I noted the sensor below had oil in it(I think it was leaking around the pins) so I cleaned the sensor harness connector and hooked it up. Nothing, no difference. The disconnected it... same thing. I even jumpered the two pins to see if that made a difference. Nope, I checked for codes with the VCDS as well. Nothing after all that. What is that sensor and what good is it?(see below)
We have an 03 Jetta TDI as well so I pulled the intercooler pipe right off at the intake to see what difference that made just to see. It affected it a little but ran way better than the 06 TDI and I could hear the turbo spool up with the pipe right off.
I noted the fuel in the 03 smells alot different than the 06. I think I might expolre that avenue next. I am in Northern Canada and we have 3 types of fuel "Regular gasoline", "Supreme Gasoline" and "Diesel" and that is it.
The car was from PA, USA and I know they have ummteen types of diesel down there... Bio diesel, this diesel, that diesel, the other diesel, vetegable oil diesel and all that noise etc etc...
I think I'm going to drain everything and put our "Diesel" in it cause I know it works! I have no idea what is even in there right now. Could have "gasoline" in it too for all I know.
