Reinitialise the Electric Windows

Last updated: June 6, 2026

Lost the one-touch (auto up/down) on your Audi Q3 Mk2 (F3, 2018–present) after a flat or disconnected battery? The window motor has forgotten its top and bottom limits. You re-teach them by hand in under a minute — no tools.

What Happened

The controller stores the fully-closed point so one-touch can stop neatly and the anti-pinch can react. Cut the power and that memory clears, leaving hold-to-move only.

Re-teaching a Window

1. Door closed, ignition on.
2. Pull the switch up to close fully and keep holding 2–3 seconds past the stop.
3. Let go, then push down to open fully, pausing at the bottom.
4. Pull up again to close fully, holding a couple of seconds at the top.
5. Release and check one-touch both ways.

Do each affected window from its own switch.

Not Working Yet?

• Hold longer at the top so the controller logs the closed limit.
• Shut the door and make sure the battery is healthy during the learn.

Frequently Asked Questions

Why did my Q3 windows stop auto-closing?

A battery disconnect or flat battery cleared the learned travel; re-initialise to bring back one-touch.

How do I reset the auto window on an Audi Q3?

Hold the switch up to close fully (2–3 s), then if needed open fully and close fully again, holding at the top.

Every window?

Just the one-touch ones, each from its own switch.

Tools?

None — it’s all done at the switches.
