PS got off the blower to mechanic initially he said yeah just bring it in for us to sort out,I mentioned the actuator he said could be, then he went on a tangent about it maybe being the turbo etc etc and of course it could be....but nope ain't willing to be without car for another 2 days....as he said needs to be sent off to specialist if it is indeed the turbo etc etc ....may just order a a new valve be done with it and see rather than try to clear it up....gonna dig around see how easy it is to remove and clean the pressure converter 11747796634: Pressure converter
