dashboard turbo gauge

[mrdarthvader]

Can anyone advise possible problems if the turbo gauge in the dash does not light up when vehicle is running.......

The boost gauge should not move until you have positive pressure in the intake. If the gauge never moves check the vaccum line to the map sensor on the fender.

And never rely on this gauge. Its more for looks than anything, they are notoriously inaccurate.
