Instrument cluster settings

[adem.csl]

On my e46 compact and coupe when I press bc and set my trip computer to show range,I switch off the car.the following morning or day night I start up and it shows range as I previously set it
On my Csl I start up and get clock time.i scroll through to range which is what I like to observe.i switch off then go to start and it reverts back to clock time.
It doesn't reset the clock to--:-- it shows what ever time it is
My question is does anyone know how to set it to memories the range setting I want to observe?both other e46's keep range if I turn off at range,if I set it to mpg when I turn off when I start up its n mpg.and so on so forth but Csl will revert back to clock
