Hi Guys

Like the title says if i hold the throttle open about 2500 the revs seem to fluctuate and an intermitant whooshing noise can be heard, the car drives fine (I think) car done nearly 30,000 and has been serviced accordingly, any idea's?

Loose intercooler hose? Check the two which should connect to it. Or the turbo hose.

Check the air ducting around the air filter, turbo, and intercooling for a loose clip first.
