Hi everyone. Hoping to get some advice about the turbo system on my car.It's a 2005 1.9 TDi PD SE touran.The car would run fine for a mile or two then it'd be like the turbo had stopped working. Just no power at all. Switch off and it'd be ok for a mile or so then it'd happen again. I suspected MAP sensor as something was obviously resetting when it was switched off. After a week or so the emissions workshop light came on so I asked a friend to read it for me. Plugged into reader and it came back, from what I can remember, turbo pressure or something along those lines. Turned out that when I took turbo off the shaft had movement in it so I replaced the full unit. The car is still the same, no power. Took it to a garage who says it could be one of two black boxes attached to the bulkhead? Any idea what these boxes are and how it affects the turbo?

Hi, I'm an owner of a 2005 Touran 1.9TDi PD SE with 72k original miles on the clock. Hobbies are motorcycling, all grain brewing and making biodiesel. I live in Manchester and I'm a tram driver. Glad I came across this forum. Take care everyone. Glyn
