No boost on turbo

Could be a sticking dump valve it’s internal to the exhaust manifold but is air operated small pipe from n75 valve

Have you checked the dump valve operation, mine was difficult to move by hand let alone air pressure, if this is letting air out you won’t get the charge pressure required = poor pick up & performance .

Yh it moves As it should so the mechanic says Keith thinking of taking some over garage

Have you looked on the forum to see who is near to you with VCDS for a free scan , this is an Audi main dealer level scan
& doesn’t take more than 15 minutes to complete.

That’s my next step tomorrow to look for the someone with a VCDS. am lucky at the minute as my best friend is a mechanic so it’s only cost me parts at the minute so we’re going to change the fuel filter he thinks it’s a cheap one that we put on when we serviced it. If that don’t work after that then I’m gonna have to look for someone to scan the car
But am sure I paid something like £28 for the filter ?? I just wish I could get it back running right because I love the a2
I’m really grateful for everyone I’m really grateful for everybody’s suggestions thank you
