Does the 2018 Audi A3 have auto start-stop?
On some configurations. Yes on the 1.4L 4-cylinder turbo plug-in hybrid. The 2.0L 4-cylinder turbo is listed both with and without it, depending on the build.
Key takeaways
- Start-stop cars restart the engine many times per drive, so they are usually fitted with an AGM or EFB battery - replace like with like.
- Most systems have an off button that disables start-stop until the engine is next started; some models remember the setting.
