1.9 turbo problem fixed thanks to the forum

Ive posted before in one of the sub forums about the low boost problem I must have had since I bought the car a year ago, but would like to say how helpful you guys can be. I did not actually realise I had any problem at all since changing from a 1.8TS, just put it down to diesils being a bit sluggish on take off. However, I recently drove a new golf turbo, and my lord, what an eye opener that was. So I got a diag at a tuners, which said low boost at low revs, and doing a search on here led me to suspect the vacuum valve on the radiator, since I couldn't see any obvious faults with the vacuum piping. Did a final check on the pipes though, and found a tear in the section that goes into the turbo beneath the car. I've just replaced it and .... holy ... (it is a sunday), what a difference. Turbo gave brief whistle of delight when I started her up, which has not happened again thankfully, and the drive is transformed, It has also stopped the judder when switching off the car, something else I had thought was a diesil thing. Chuffed, so thanks.
