Loud knocking when stop/start kicks in

    2016 Audi A1 1.4 TFSI Manual.

    Got a loud repetitive knocking/clunking coming from the passenger footwell area when the stop/start kicks in when stationary and in neutral. Goes away when the engine starts again.

    Booked it in for investigation at local Audi dealer - 3 week wait!

    Can't find any similar problems on any forums.

    Any ideas what it might be? What is still running whilst the engine has stopped?

    I can't get out and open the bonnet to have a closer look because undoing seat belt and/or opening door disables the stop/start.

    I'll probably disable it on the dashboard each journey until it's looked at.
