If the mode and set button do not work, it sounds like water has gotten into the MFD, and caused damage, looks like its time to find a replacement.

Sometimes, but the odds are against you if the buttons are not working.

The more common failure is having segments of the LCD digits fading. The repair method is well documented. You can use the same method to cut open your display and see whether you can get the buttons working.

See the MFD section of my signature links for the details.

The MFD should 'wake up' when the engine starts. You will see the display do a self test and then settle down. If the buttons are not working you will not be able to change the display modes.

The MFD will go to sleep after five minutes of no activity and engine off. This mode shows the clock. The fuel levels may be visible but are not updated while the display is sleeping.

i have posted video elsewhere of what all the MFD display modes look like.

Unplug the Deutsch connector from the back of the MFD and leave it disconnected for more than ten minutes. Leave it disconnected as long as possible.

When it reconnects the clock time should reset to 12:00. See if the MFD now works properly.
