It happened again today after 6 days of acting normal. Normal for it is sitting in a garage covered by it's cotton t-shirt. this little Queen or whatever is a real Wuss when the humidity is high......and after you shut down and re-start, it acts fine except the check engine light stays on for another few hours!!!!! I'm thinking.....did BMW hire old Lucas people to to their electronics/wiring??? This has shades of the late 60's memories when a tow truck became part of the Jag experience. We'll never have high milage on this one cause its goin' be in my garage or BMW's garage for a long time!!! My wife thinks its because I drove it over 90 mph a couple of times!!! It's her thingy....so who knows????????????
