The 2015 Audi S3 features a timing chain in its engine to maintain synchronized timing gears. Unlike a timing belt that requires periodic replacement (every 60,000 to 100,000 miles), the chain does not need to be replaced. Typically, a timing chain can last over 300,000 miles. It's recommended to inspect the chain annually during servicing to ensure it's undamaged and securely in place. Additionally, it's advisable to replace the water pump, located in the timing assembly, approximately every 100,000 miles.
The 2015 Audi S3 comes equipped with a timing chain.
Absolutely. I reached out to the Audi service department, and they verified that my 2015 Audi S3 Premium Plus is equipped with a timing chain. The technician explained that the "Accessory Belt" only requires replacing if there are any problems with it. This belt is responsible for operating components like the A/C unit and alternator.
