Power Loss, anyone help with these error codes

A3 2.0L 6 speed Manual S-Line quattro sportback

On the way to work tonight I lost power above 2000rpm in 6th gear and the engine management light came on. I've had the AA out and he's reset it all and given me the fault codes, can anyone point me in the right direction?

Turbo overboost
P0234
P0234+

Many thanks,

possible

manifold vacuum unit stuck or tumblers collapsed in the manifold (picture number 1)

vacuum pipe collapsed under boost, then reforms when vacuum depletes

if the problem goes after switching the engine off and then back on then its likely to be a sticking turbo

miti vac test the circuit and inspect the vacuum system under pressure, if the pressure drops then there's a leak

if the actuator moves freely then the turbo is ok

Ok thanks for your reply although most of it's gone straight over my head. Lol. I'm going to check all the pipes are secure etc but other than that I will have to pop it to an audi and BMW specialist in Banbury as it's above me.

Gulp....
