Throttle hang ?

[roofrat]

Hi to you all , I am a newbie from Cornwall and I have an anoying problem, with my lovely A4 Cabriolet

It has 110,000 miles on the clock with full service history two previous owners. It runs sweet as a nut 

never misses a beat , But if I wind it up through the gears the revs seem to take forever to come down.

the car is manual 6 speed, I can replicate this problem whilst stationary if I plip the throttle can any one 

help me?

All the best Roofrat
