Hi Folks,

I have an overboosting Bora 19. TDI. I put the pump on the actuator and it holds a vacuum, it also moves fine - the full 2cm range of motion - nice and smooth.

Does this rule out a sticking VNT vanes?

I've tried the usual suspects: EGR fine, MAF changed, N75 swapped, vacuum hose changed.

Could it simply be that the previous owner had it remapped and botched it?
