    Default SID803A Version Help

    Hi All,

    I have a Volvo C70 that has a SID803A 5WS40562A-T

    Does the 5WS40562A-T indicate a software version on the ECU or a hardware change?

    I would like to create a backup ECU and was wondering do I need a SID803A with exactly 5WS40562A-T on it?

    Many thanks
