Don't know if this helps but I saved it in my 'information' file......It relates to resetting the calibration for an 09 +4 and I don't know if much has changed before the build of your car?
The code for an 09 Plus 4 is 008386, assuming there is not more than 1 version of the milometer in use at the time. To operate, press in the ‘trip’ button under the dash while starting the car and using the button set each number in sequence as it flashes in the milometer. Allow it to revert back to the milometer reading and all should be well.
