Hello nick i had one of these that drove me round the bend. The first thing to check is if there is engine oil in the petrol if there is then high pressure pump needs changing quite common apparently, if this is the case you have to change the low pressure pump in the tank which has been updated because of this problem.I am sure there is more techical guys to explain better than me but it something to do with the oil blocking the fine gause filter inside the low pressure pump which is completly internal to that pump, which then gives high pressure pump & rail poor quailty of fuel (air bubbles) that high pressure pump & rail pressure sensor can't control giving HIGH pressure problem.I do have a TSB some where at work if needed.HTH Darren
