[Mk2] [Turbo] Problems with digital boost gauge

[jimbo1989]

Yesterday I fitted a digital boost gauge but it is reading maximum boost when the engine is ticking over & then goes down to zero when it is actually boosting. I have piped into the pipe under the turbo pressure sensor before the filter as this is what I have been told to do. As far as I can see the wiring is correct but is wont read correctly..

Just wondering if anyone can shed any light on this??

did you ever get this fixed from the advice on the oc?

no, I have given up, going to send the gauge back to manufacturer and they can test it... might be knackered so am basically p1$$ing into the wind - we shall see...

Try hooking up a 12v source for the gauge, and the pressurise the sensor with a foot pump. See if you get the same reading.

I'm assuming that it has a electronic sender unit? Does this have all the required fittings? Is it earthed?
