Re: VNT Freed Off

having read that, it sounds like the rod length has to be set up first - this being wrong would/could cause the problems listed, such as overboosting etc.


"It is only when the ‘minimum vane open' position is set that it is possible to calibrate the unit "

Thats what I got from the above.

Thankyou BTW, for your hard work and efforts here in sharing your knowledge, it helps people like me to understand a little more about it all and puts the theory to the broken turbo I have in bits on the kitchen worktop!

do I take it that all the above problems relate to power being down? I have p0235 problem showing (overboost sensor) but power is good throughout the range, just get huge smoke on hard acceleration. new egr fitted + new top turbo hose, I do like wasting money so am about to buy a new actuator solenoid or MAP, which is most likely, given that the car is going fine, just single handedly destroying the planet!

Yours is likely to be a split boost hose.
