"For vehicles with Motor extended operation circuit or UNMASKED OFFICIAL VEHICLE or Patrol vehicle, camouflaged or Integral active steering" OP, if your car has any of the above, there's your answer. |

Yes Thanks, I Have Integral Active Steering.
Was A Bit Surprised, Cause When I Leave The Car Standing For A Week Or So The Display Stated That The Car Was Starting From Back Up Battery. So I Looked In The Boot And Found A Motorcycle Battery! Thanks Bimmertaxi & Jon |
