Any ideas on what could be causing it ?

It’s hard too see but how’s it driving in general and what’s exactly happening

Dunno but I think you need brake fluid (light on dash is the brake warning one)

semms alright tbh part from setting off n sometimes when pressing back down on accelerator it will serge boost then die down again , but while driving like going to over take boost will start to come on then it will just ccome on and off like its trying to but just carnt quite do it like if you listen to the engine as you watch the boost gauage

do your self a favour and delete that video asap ...2 offences plain as day...never ever show the speedo for a start
But anyway...yeah looks like either the boost valve is opening early due to the map sensor thinking boost is higher than really is so may need a new Map sensor Or
Wastegate spring could be getting tired and opening on its own under boost.
