That's strange that your boost reading are in psi and not mBar . Maybe i never used my vag-com to check boost. I know in metric it's 1900-2100 mBar. Do the conversion maybe?


Yea I converted it,

I was getting readings as high as 2500mBar

The other thing to note (which you may be factoring in already?)  is that the MAP, and hence VCDS, reports absolute air pressure rather than relative.  So, when you're thinking in terms of "boost" you need to subtract local barometric pressure... something in the neighborhood of 14.5 psi, depending on altitude and local weather conditions.

IIRC the troubleshooting info in the Bentley does in all in absolute, just to avoid confusion.

I might of messed up the calculations but the Problem is solved...N75 valve is cracked and the Vacuum line is busted

It was the N75 Valve that was acting up, I replaced it and the Vacuum line going from the Turbo to it and put the VAG COM on it and took it for a spin, at 3000RPM in 3rd then going WOT the Boost stayed in within Spec :D
