Thanks. I was thinking that I'm pushing my luck on the main battery anyway. I might have some of the coin cells at work...will find out tomorrow. I have been a visitor to this forum for over a year now. I had the tranny sensor problem, cost me $900 to get fixed last Fall. out of warranty. Chrysler dealership is a waste of time. Love to sell tires and oil changes but tell you to go away when anything of substance happens to the car, excuse is they have no XF tech. I get compliments on the car constantly...just wish I could have gotten a white one instead of black. Can't be picky when you buy used and get a great deal!
