From the model year 2000 to 2023 the Audi S3 has various engines with either a timing belt or a timing chain. However, all of its engines are interference. Scroll down to see specific data for your model year below. The timing belt (or chain) maintains the proper synchronization between the various engine components in a combustion engine.
I have a 2012 Audi Q7, great car except for the hideous 2-3 rattle noise on cold start.
