I can not believe that even after 252 posts as recent as TODAY people are still experiencing this problem and no one knows for sure what s/w rev and/or engine temp sensor actually fixes it! I would have hoped that recent builds would have the latest s/w and h/w and this would have been a long gone issue. Yet, ccgp reports that he just picked up his car yesterday and the problem exists. Oy vay.
