I've had this fault come up 6 times now in the last few hundred miles:

Boost Pressure Regulation - P0299 - Control Range Not Reached

Last time was yesterday, 5518 rpm 81% load 150 km/h (apparently). It always seems to happen high up the rev range under heavy throttle.

Haven't noticed anything wrong. Drives ok, I wouldn't say it drives "great" but I imagine it drives like any other GTI. Seems a bit jerky at times. Clutch is knackered (but that's another story)

I've seen on the Ross Tech page there's a few things it could be but has anyone had this before? Running stg 1.

Cheers,
Scott

Possible Solutions:
Check Hoses/Pipes to/between Components.

If the Turbocharger is faulty due to mechanical / internal problems or the exhaust system is restricted (typically the Catalyst) this fault may be the end result.

I would not be suprised if its the diverter valve. Common issue which I think mine also has.
