2025 Audi RS6: known problems and what to check
Cars registered in 2025 haven’t had their first MOT yet (it’s due at 3 years old), so there are no MOT results to show. Here’s what we do know about the 2025 Audi RS6, and what to check before you buy one.

Questions to ask the seller before buying a 2025 Audi RS6
Ask before you travel to see it. A seller who knows the car will have answers, and receipts.
- What has been fixed under warranty, and has the software been updated?
- Can I see the service history and receipts for any big jobs?
What to check on a 2025 car
- Warranty left
Ask for the date it was first registered and check how much of the maker’s warranty is left, and that it transfers to you. Electric and hybrid batteries usually have a longer, separate warranty.
- Servicing
Servicing on time with the maker’s schedule keeps the warranty valid. Ask for the service book or the dealer’s digital record.
- Finance
Nearly new cars are often still on finance. A history check shows outstanding finance, and whether it has been written off or stolen.
- Recalls
Ask whether any recall work has been done, and check the reg on GOV.UK’s free recall checker.
- Logbook (V5C)
The name and address should match the seller, and the VIN on the V5C should match the car.
