Hi radio is radomley, turning on by itself when car is turned off. Spark plugs were recently changed! Pull the fuse until you can go to the dealer. Good Luck! Ok so after two days of the radio not turning off (and when I turned the radio off, the Sync display would still stay bright, and there would be a VERY faint glow to the speedometer and instrument display) the problem fixed itself. Now when I take the keys out, the radio turns off and the 3. Insufficient Coolant. If your coolant level is low, there is a chance it is pushing air into the cooling system, and the coolant temperature sensor will not read the coolant temperature correctly. If the coolant level is low, you need to top up the coolant reservoir. Dashboard lights staying on permanently for a couple of days and completely killing the battery, but then it can go for a few weeks without doing it and it'll start fine then and it happens completely random. Done a parasitic draw test and it's running at 0.50 when dash lights stay on but runs at 0.18 when they're off. Here are the five most common reasons the ABS Ford Fiesta’s ABS light comes on: 1. Wheel Speed Sensor. A typical wheel speed sensor. A bad wheel speed sensor is the most common reason the ABS light comes on. There is a wheel speed sensor on each of your Ford Fiesta’s hubs. Wheel speed sensors monitor the rotational speed of each wheel and It is quite possible to have a noisy bearing with absolutely no sign of it with the car jacked up. No play and no noise. I had this for about 2000 miles. It stated as a faint drone at about 50mph, and over that distance it slowly got louder, and became apparent from about 25mph to over 70mph. But still no play or roughness. Dec 17, 2015. #2. TheStig said: I know this is the wrong area but my Sync took a shit this morning apparently, the volume adjust wouldnt work while driving so i tried to change the station and that would work. Even hit the power off button on the radio and it says its turned off via the screen, you can even press it back on, scan stations, etc. gdo2ThM.
