Noticed recently its not a fluid motion (the needle), sort of flutters. It boosts fine, drives very well etc i just wondered why it would do this? Gauge going dodgy? The make, i cant bloody remember but its located in the A pillar.

 

Have you played around near the vacuum hose lately...??
If not try another gauge might be sticking..

 

analogue or digital ?

 

Its an anolougue gauge. It may have allways done it. I have a feeling the gauge is playing up as like i've said the car drives spot on.

 

could try one of those little inline foam plastic filters

 

Youve lost me (its not hard tbf)
