Pulled away from a junction fairly quickly this evening. The boost came on and then suddenly dropped off. There is virtually no boost at any throttle level. I didn't notice any significant smoke out the back at the time and there is no smoke now when driving. The car has a decent level of oil and water. I can't see any boost pipes off but then it is very difficult to see properly without decent investigation. Any thoughts would be very handy.
Many thanks
