Right i was driving along and heard a ping noise, now the car has a sucking noise as it comes on boost at 2k revs still boosting on the 1st it has this sucking noise right up to when the vod would happen then it just flutters away and no boost on 2nd, had a look and nothing is loose took the top mount off had a look and cant see anything off, what could this be??
 
have a look at the solenoid pipes...there is a black box on the left side of the engine bay, by the air intake....in there there are a number of pipes...make sure they are all connected...be careful disconnecting them makes sure you do it 1 by 1
The fact that you have no boost at all but sounds more likely that on of the hoses from the inter-cooler has blown
 
Took the intercooler off everything is connected, if it is the solenoid would it still be making that sucking sound?
