X5 3.0d Faults...

[Dingus]

Hi from Greece!

I recently owned a new X5 3.0d (E70). Everything was ok till last week when I saw th 1st error message to the display: "Parking brake failed... contact BMW service".
I could noy believe that ! A brand new car car that costed 95.000 Euros to show such a problem ! Car has now only 4000 Km !!
I went to BMW service where they checked it and told me that it needs a new parking motor (!!!) and I have to wait for 10 days! This happened last Friday.
Today morning the display a new error message: "Level Adjastement Error (or something like that- I do not remember now)...contact BMW service".
I do not know what to think !
Does anyone have such an experience ? Is it bad luck or what ?
Is it normal to happen such faults ? So often ? What can I do ?
What can I do in such a situation ? just waiting for repair or can I demand anything else ? I do not know, I am just so dissapointed !
Please tell me your opinion !
