Refer to your vehicle's manual for specific instructions on how to perform this reset. If the warning light remains illuminated after these steps, it may be time to consult a professional mechanic or an authorized Audi service center for a comprehensive diagnosis, as the issue could stem from faulty sensors that require replacement.

What could cause the tire pressure warning light to remain on in a 2019 Audi S5 Sportback?
