    Default Mercedes Vito 2015 W447 A4479004007 EEPROM file needed

    Hello,

    I have a Mercedes Vito 2015 W447 A4479004007 Dash.

    The display is has no backlight, coused by EEPROM corruption in my opinon.

    Can someone supply me with working EEPROM data?

    Virgin and/or with 56800km would be perfect.

    But any file is welcome.

    Thanks in advance

    Hi eFighter, got one in today with same problem, don't know if it's been messed with or if its a common fault.

    I take it your problem was not data related.

    Could you point me in a direction to save me some time?

    Kindest regards,

    Hi

    I think the problem can be come about can quality can filter because if you connect cluster without can filter in the car and make the ignition 1 after 30min approximately LCD light come back
