2019 Audi A6 2.0L Diesel · VF19 ZNX

The 2.0-litre TDI diesel in this A6 typically returns 55–65 mpg on a motorway run and 45–55 mpg in mixed driving, depending on driving style and traffic conditions. Road tax (VED) for a Euro 6 diesel of this value should be in the £150–£180 annual band, though vehicles over £40,000 new incur an additional £390 supplement for the first five years — confirm whether this premium still applies to this particular car. Insurance for a 2019 A6 typically falls within group 30–35, so expect premiums in the £500–£800 range depending on your profile and location. Routine maintenance including an oil and filter service runs around £200–£300 at an independent specialist, with main dealer servicing typically £350–£500. Major items such as brake discs and pads, tyres, and a timing belt service (if due) can push annual costs considerably higher.

On the test drive, check for any dashboard warning lights, particularly the DPF, AdBlue, and emissions-related indicators which are common areas of concern on diesel Audis. Inspect the exhaust system visually for any signs of corrosion or blue smoke on startup, which could suggest turbo or injector issues. The 2019 A6 is generally reliable but owners occasionally report dual-clutch automatic (S tronic) gearbox hesitation and water pump concerns, so make sure changes are smooth and the transmission behaves predictably in both manual and automatic modes.

Although this particular MOT record is free from defects, the model-wide top failure reasons are headlamp issues, tyre-related defects, and anti-roll bar component wear. Carry out a thorough walkaround looking for any uneven tyre wear (which could indicate tracking or suspension issues), check that all headlights produce an even beam pattern free from condensation, and listen for any knocking from the front suspension over speed bumps. Under the bonnet, look for signs of oil leaks around the turbo and engine sump, and verify coolant and oil levels are correct. Finally, check the condition of the undertray and inspect underneath the car if possible for corrosion, which can affect diesel Audis used for high-mileage motorway driving.
