That's a good question so I've checked. RAVE says that the answer is no. The BCU enters sleep mode sixteen minutes after the ignition has been switched off (provided that there have been no triggers during that sixteen minutes). The bonnet switch can be closed or open at the time that the ignition is switched off and the BCU will still enter sleep mode. But if the bonnet switch changes state during the sixteen minutes, the BCU will awaken.
