MFA screen blank in cold & time adjust buttons dont work

[ross.taylor 0]

Whenever I first get into my car and it is anything less than boiling hot the MFA screen is either totally blank or only shows the left half of the screen. As I drive and it warms up more and more of it shows up. It normally takes around an hours driving before the whole screen shows up! Does this mean that I need a whole new MFA or just a new screen? Is there some cheap way to sort this? Is it a very tricky job as I suspect?

 

Also the time set buttons do nothing! They just rattle around in their holes. To set the clock I have to disconnect the battery at midnight!! Is this new MFA time to?

 

Lastly the outside temp shows a permenant -40degrees. I'm assuming that this is a sensor fault. The car had a front ender before I got it, so I guess that the sensor is missing or knackered. Are they cheap and easy to fit? I believe that they are behind the front bumper, does anyone know exactly where and has anyone actually ever fitted one? Part #?
