    is it possible to reset the ecu back to the previous setting my ecu was updated now got the dreaded svs

    No once the software is updated it cannot be reversed. Did you manage to get the car on opcom or tech2 yet? Pretty sure once you do that you will get the info you are looking for. No matter what software is on the ECU, if there is a fault causing the SVS light to be on then it will show anyway.
