Found 1st issue with my car:

The driver windows can auto down but when you click auto up it goes halfway and wind down again. I saw in V8 or V9 of this thread that some had this problem.

I read the manual and it says that the window is simply out-of-calibration. The manual asks you to wind up the window, clicking up until the window closes. Then release the switch and click up again for at least 2 seconds.

I did that although I clicked for 10 seconds. VOILA the window operates normally again.

I can't remember which page but I am 90% sure that this is mentioned in the manual.

Hope this can help other Preve owners.

Regards.
