Hi all

This morning driving to work, my 4x4 saph suddenly lost the ability to boost!

One minute seemed fine, i accelerated to get past a car and there was no power. Pulled back in and tried accelerating but no power at all. The needle doesn't even get fully to 0 on the boost gage.

Also whilst idling it seemed to puff out a bit of bluey/white smoke, but strangely it was at regular intervals - every 20 seconds or so it would chuff.

I've put a holiday in and drove back home - all boost pipes look ok, intercooler looks ok, just waiting for it to cool a bit so I can check the turbo shaft for play. Could it be the actuator? Any ideas?

Thanks for reading...
