My new Jazz has a problem with the a/c. When it is switched on there is white dust particles coming through the vents and landing on my dashboard and drivers seat. The particles look like small snowflakes. I have noticed that there are some posts regarding this problem on the BMW website as well and they say it maybe a problem with the evaporation core made by Denso. I thought it was because my car was new and settling in however I am hoping that this is the case as I would not like this to be an on going problem. I thought I was on to a winner with my new Jazz, so I hope this will sort itself out as I am a wee bit disappointed in it now.
