Boost guage not working

[Shy260]

Hi guys my boost gauge has stopped working car runs the same just wodering where to start cheers

What type of boost gauge ? Mechanical, digital ?
What exactly isn't it doing?
Start by checking the boost hoses to and from the gauge and/or 12V supply of digital.

Are we taking Diesels?
If you have vacuum on your boost line that will explain why it is sitting on zero...

Pull the line off the back of the gauge,
Blow thru it (back towards the manifold),
If you can't the line is blocked
If you can either the line may be split or the gauge is knackered,
Grab a bike pump or a low pressure source of air (mouth if that is all you have) and blow in the back of the guage and see what happens

All hoses seem ok do the guages fail

All hoses seem ok do the guages failThey can definitely fail. I had a mechanical one, pointer needle came loose on the inside and was stuck at the bottom.

Yes. But heres what I would do. Remove the gauge from inside the car. Zip tie it to your windscreen wiper, install new hose from the boost reference point and then too the gauge and see what happens. This will rule out the hose being kinked, holed etc etc. If still no joy, the gauge it buggered.
