    Hi all,

    I want to clean up my battery terminals so need to disconnect it. I had errors thrown up while driving so think it was a battery issue, all solved itself after leaving the car off for a few minutes.

    I read online that a battery disconnect resets the ECU and also requires a TBA.

    Can anyone confirm if this is necessary, or does it not matter?

    Is there a way to reset it without VCDS, some posts say to just put ignition on and floor the accelerator for like 10 seconds or something.

    it is a 2016 Polo 1.0 TSI.

    Thank you
    Ji

    It should be done but isn’t always necessary.
    A petition has been started to allow the use of synthetic fuels when they become available, this may allow the continued sale of ICE vehicles post 2030 and the use of classic vehicles well into the future… Their use may even be able to rival electric vehicles given the chance. Please sign this petition IF you feel the infernal combustion engine has a future if sustainable fuels are made available

    Ok thanks crasher, guess I can risk it and hope all is well when I disconnect it, lol.

    How can I know if it's throttle cable or DBW, & more specifically which connection method ? (UDS, KWP-2000 / CAN or KW-1281?)

    It is drive by wire, without VCDS that is all you need to know.

    I have access to VCDS at my dads house, so that should tell me, right?
