Hi there i have a Wreg 2l HDi 406 and im having a problem with the turbo. The car used to be a taxi so has got plenty of miles on the clock but the problem is that i have got no turbo until 3500 rpm but by that time i have got to change gear!! Does anyone have any idea wot the problem may be????

Mine's run out of puff by then Tried the vacuum pipes and solenoids on the bulkhead? Can you actually hear the turbo spinning up?

Not tried the pipes or solenoids but the turbo is spinning i can hear it
