Hello. Many thanks for all your comments and advice,We did scope the pressure reg and fuel rail pressure sensor yesterday as Dave suggested, which gave a better insight to the changes.What we found was that the fuel regulator was being instructed first and then noticed the resultant change from the pressure sensor[should have used scope first!].This looks like an intentional instruction from the ecu,We have the car booked in at the dealers this afternoon to have the latest software patch installed if not already up to latest version.Keep you posted. Thank you Trevor. |
