Before you buy
- Get the 17-character VIN from the seller and run it at nhtsa.gov/recalls. It shows which recalls are still unrepaired on that exact car.
- Verify rear axle lock nut and alignment recall completion.
- Request rear seat belt recall repair documentation.
- Test the backup camera and ask about lane departure faults.
- Open recalls are repaired free at any Audi dealer, whoever owns the car — an open recall is a to-do item, not a bill.
