Clock reseting --:-- Warranty? - Australia

[avp27]

Hi all,

I have recently purchased a x5 3.0d with low kms. Within a day I started to experience the clock reseting issue. I have read through the various threads and wanted to see if anyone in Australia could share their experiences. Why ? I called the dealer, and they told me that is was due to my driving pattern. Short trips, the battery doesnt have time to charge up, therefor the car starts to shutdown some of its features. Though that may be true...it find this unacceptable. Has BMW acknowledged this as a known issue and under warranty what should I expect from the dealer.

thanks !
