    The main (console) OBC display has started to breakup and show random characters. After parking a while the display is back to normal. Also, the dash illumination flickers and can go off entirely the return.

    Any advice on fault checking/fixing?

    Thanks.

    I would leave it to see if it settles down once we are back to normal temperatures.

    Good to know


    When you say "dash illumination" goes do you mean all dash lights or just the OBC lights?
    Do the buttons stay illuminated? If the buttons go out then you may have a power issue, check for loose wires / intermittant power before worrying about the finer detail.

    I mean that the characters on the OBC display breakup and flicker and ultimately go blank.
