Before you buy this car
From the generation guide
- 3.0 TDI pull-away: drive a 50 TDI or S6 from a stop and at low speed. Bad: a long hesitation before the car moves. Ask whether the engine and gearbox software updates were done.
- Recalls: ask an Audi dealer to check open campaigns by VIN, especially the panoramic roof, passenger airbag and rear axle campaigns.
