What information is held on a BMW 1 Series keyfob?
I was wondering if you knew what info the keyfobs hold, as I have been told they hold info like the mileage, the last time the car was driven, when it was last unlocked and any faults with the car. I just wanted to know how true this was, as I have a bet with a friend that they can't hold so much data as that sort of info would be stored on the ECU.
Everything regarding the information held on the key (primarily for servicing) is explained in detail on BMW's website.
