    Start button in a 2021 Audi Q5 not working properly
    Answered by David Morley · 23 April 2025

    You could have a problem anywhere in the wiring between the starter button and the starter motor. It could even be a problem with the starter motor itself. This function is computer controlled, too, so you may find the body computer is the root cause. An auto electrician will be able to check this out and diagnose the fault.

    But there’s one thing you can check before that, and that is to remove and clean the contacts on the actual starter button. You will need to remove it from the dashboard (disconnect the car’s battery first) and carefully take the button apart and spray some terminal cleaner or contact cleaner on to the contacts. If you’re not confident to do this, the same auto electrician will be able to help you out.

    These buttons (which are really switches) accumulate all sorts of grime and moisture from the air, the car’s interior and, of course, the fingers that operate the button.
