My 2013 non-AP P85 was just at the SC for TPMS sensor replacement/upgrades (I now get the individual TPMS readings on my console) and I received this firmware upgrade while it was there as a result. Not sure if it was a requirement for the TPMS upgrade.
Remind me again what the issue was with the recirculate mode? I can check if it was 'fixed' in this FW.
[edit]
nvm. i checked the Firmware8.0 thread and then went to my car and see the same release notes about the fan fix. and AFAICT, yeah, fan setting '1' on recirc works fine.
