Getting a vag com is a good first start. You know the boost is having a problem, try datalogging boost requested vs. boost actual. Also check all the turbo vacuum lines and VNT actuator for movement. http://www.myturbodiesel.com/1000q/a4/VNT-wastegate-adjust.htm

Thanks, hoses and wiring seem fine, actually look pretty new, the car only has 115,000 kilometres (70,000 miles). I'll be going on to the next items.

Don't be fooled by lovely looking pipes, the vacuum pipe's that cheap you'd be as well to change it anyway, it would help rule it out if nothing else.
