Hi mate, Sounds like you need to check the error codes. With the engine off, lift the bonnet and you'll find the diagnostic box near the passenger side suspension turret. Open it up and using a bent paperclip push one end into terminal TE1 and the other end into E1, now turn the ignition on so that the dash lights illuminate, do NOT start the engine. The engine management light will start flashing, if it flashes constantly then no eror codes are stored. As an exmaple: if it flashes 5 times and then pauses and then flashes 4 times then you have code 54. If it then does another sequence then you have more than one code stored. Try it and report back with what you findings HTH
