Hi guys wife came home and told me the cars making a funny noise so went out and took it for a drive, under load as it boosts I can hear a strong boost leak but still getting plenty of turbo pull, popped the bonnet and got her to hold the revs up to bring some boost in and it sounds like its coming from drivers side front behind bumper but I can't see without taking arch liner off or undertray and not had time yet,is there any known pipes or joints known for leaking around that area?
 
Standard intercooler metal hose runs along the front under the radiator. Could be rotten on the weld seems or the hose has split where it joins the pipe.
 
Cheers for reply mate, removed airbox today and got a torch down there, looks like its blown a hole in the rubber pipe from turbo to metal intercooler pipe!
Just phoned tps and the guy reckons £197 for a small rubber pipe lol
Surely he must have been looking at the wrong part!
Ordered one off eBay for £20
