    Question Can I reset an ECU to 'new' condition? ...

    I'm about to replace the Battery Management ECU - 4E0 915 181 - on my 2005 D3 A8 with a newer second hand unit with a later level of firmware.

    Obviously this will have the battery logs of the car from which it was removed.

    I know I can do a 'sort of' clear by changing the battery serial several times with VCDS but is there anyway that VCDS can instigate an ECU reset to some sort of 'as new' state?

    Thanks - Julian

    Unfortunately this is only possible by flashing the module and not something VCDS can do. You don't need to do it anyway.
