gt tdi 115 loosing power

[beaniecom]

iv have this problem since iv had the car i would say. starting the car from cold and driving it is great the power is there and there are no problems. it is when the car has warmed up, it just seams to loose boost at 3000 rpm but only when going from 2nd to 3th or 3th to 4. so if i drive say 30mph in third and floor it, it would go round to 4500 rpm no problem, but as soon as i change gear and floor it. it seams to give up at 3000 rpm.
this problem seams to be getting worse but still it is fine when cold.

any ideas?????

oh by the way i have vag-com and no fullts at all .

thanks for the help

Sounds like the MAF unit to me. It wont bring up any faults on the ECU they just get dirty over time and cant read the air comming in right !

there about 65+vat from the dealer

Yeah definiely sounds like the MAF, usually the turbo cuts out every now and again. Cheap as chips on e-bay.
