I have the latest update installed that came on the USB stick Ford mailed out. I have also pulled the negative battery cable and left it off overnight since pulling it for 5 min was no help. This is the 3rd time this has happened and the first time pulling the cable didn't help. I've searched the forms and the best result I found was here
but no solution was found. Any other idea? The Focus is a car that's engine noise is not a pleasure to listen to.
