Hello, I've looked on google for the past 30 minutes and cannot find anything to help me, questions have been asked but not answered. Out of the blue the odometer, mileage reading started flashing on and off in time with the clock seperation dots. It's at 48900k, I ruled out it being for a service? As the service light would come on? At the same time this happened, the USB port stopped working. The light behind the USB symbol will flash on for half a second every 10 seconds or so, but won't pick up my previously used and confirmed to work USB stick. Any help would be appreciated. Thanks
