pressure problem

try removing connection to boost pressure switch in top of intercooler behind offside headlight
check wiring and if connections are clean then refit and try as one on my car it falted and i removed and refitted and has been ok since
 
thanks silver surfer. The cause of the problem finally came to light when I put my foot down. A sudden small bang and loss of pressure - the intercooler pipe had slipped over onto the pulley. New pipe (S/H) now fitted and car runs spot on.
