E92 climate control zones ?

[brenflys777]

Hi, my recent e92 purchase has come along with the wrong owners manual, its a 2008 -'58 320i Msport and has climate control with pax/drivers side temp controls. The right knob has a 'rest' button on it where the owners manual shows 'all' to set the pax temp to adjust to the same as the drivers side. Does anyone have an idea how to slave the pax side temp to the drivers side ? I've tried the dealer but they said to call in to explain it - which will be at least a couple of weeks away , many thanks Bren
