The Idle adjust screw can be found on the inlet plenum.... that's the alloy bit bolted to the back of the engine nearest you when you drive.
You know the intercooler - that's the big radiator looking thing on top of the motor (?)- it has 2 big black rubber tubes coming from it.... at the front it comes from the turbo... at the back (nearer where you sit!) it attaches to a silver bit of 'engine'. Stand by the passenger front wing and look about 3 to 4 inches down from the rubber pipe that goes from the radiator thing on top of the motor and you will see a lil black rubber tube.
The idle control screw is at the end of that tube - and no - not the end nearest you
The tube was placed there to stop anybody getting at the idle screw - ever - for any reason! At all.
