Yep check all piping and vacumm hose, clamps are all good and I've disconnect the battery for 10mins to reset the ecu and now the symbol on the dash has gone but still have the same problems getting on boost. The car booked in tomorrow first thing hopefully they can diagnose the problem ill keep use posted. Ps: prior to this happening I noticed my car did a strange thing while it was off. I put the key in the ignition and the dash was telling me the car was not in P and won't start. But it was in park and I started the car anyway and wentt away. Any clue why that happend?
