Hi Alan , just got in from a great afternoon holding things for mr sparks
Very thorough and although can't be 100% sure , there is a fault with the boost control solenoid and boost pressure came up as a fault . Clear fault and runs for a short distance and then limp home mode cuts in again . won't get part till next week so will wait with baited breath to see if yours is fixed with the solenoid ! also a bit of oil in the air intake getting passed the turbo , not a lot , is this normal ? he muttered somthing about seal in turbo on the way out but by this time was too cold to care anymore
