Under the bonnet; thick black pipe on your left hand side as you look at the car. Follow that down to the intercooler.  The others are from the intercooler back towards the turbo and youll need to get the car up in the air to check those

Could be clogged inlet if you haven't blanked your egr valve off or your turbo vain sticking, recently had similar prob,
I cleaned my inlet manifold and exhaust turbo and the difference it has made surprised me tbh, the vain moved fine on mine before but it kept sticking, now it feels like a new car.

Hope you get it sorted :smiley:

Check you boost pipes for leaks, I had the smallest of splits in mine which effected the boost, and check your inlet manifold as this will clogg over time making it breath less efficiently.

Have you had it on vagcom yet to see if any fault codes come up?

well well well rebult the turbo myself, no sticky vains, put it all back on car, still the same after a small fortune, them replaced map and it runs like new again, so lots of wasted money
