Audi A6 Avant
The C8 Audi A6 Avant (2018 on) is the polished executive estate - a long, low and beautifully-built load-lugger that pairs A8 levels of cabin tech with a genuinely useful boot. UK cars are mild-hybrid petrols and a 50 TFSI e plug-in hybrid, all with quattro. It trades the sharper handling of a 5 Series Touring for outright comfort, refinement and one of the quietest cabins in the class - a classy, quietly capable motorway estate that holds its money on badge strength.
How these figures are sourced — the valuation is anchored to a researched used-market price for this model (AutoTrader median, 2023 at 30k miles). Reliability, mileage and variant data are real DVSA MOT records. Dimensions, tyre sizes and costs, servicing figures and the insurance group are segment-level estimates rather than sourced per car, and are being replaced model by model.

The short version
Forecourt score
Value 46 · Insurance 27 · catalogue percentiles
The Audi A6 Avant holds its value about averagely and costs about average to run. On three-year value retention it ranks better than 46% of models.
The Forecourt score blends how this car ranks against the catalogue on value retention, reliability and insurance cost (weighted 40/40/20) — the from-new ownership picture. Higher is better; running cost is not yet folded in.

Uses current UK pump and home-charging prices (DESNZ weekly), typical-driver insurance and manufacturer service intervals. "Fuel per mile" is just the energy input — so an EV at ~9p and a diesel at ~22p make running-cost comparison direct. A guide; your own costs will vary.

How we estimate this
Indicative annual comprehensive premium estimates. The 'Typical' figure represents an average UK driver in each age band; Lower and Higher risk show the realistic spread driven by factors UK insurers legitimately price on (postcode, occupation, claims history, NCB, voluntary excess, modifications). Based on 10,000 miles/yr, £250 voluntary excess, and the no-claims bonus selected above. Always get individual quotes before buying.

Mean recorded mileage at MOT by vehicle age, from DVSA test records. Ages below three are not shown: the first MOT is due at three years, so the few cars tested earlier are a self-selected minority rather than a representative sample. Ages with at least 10 tests shown.
Reliability
Not enough first-MOT data yet. This measure needs cars registered from 2020 that have reached their first MOT at three years old; too few have so far for a figure worth publishing.
Not enough first-MOT data yet — no score. A car needs 100 first MOTs from 2018 registrations onward before this can be measured.
MOT outlook
Insufficient MOT history at this car's reference age — too few tests to compute a reliable percentile.
Things owners say
- 01The mild-hybrid petrols suit those who can't charge; the 50 TFSI e PHEV adds low-BIK electric miles.
- 02A square, usefully large boot and a hushed cabin are the estate's strong cards.
- 03The dual-touchscreen MMI looks smart but is fiddlier on the move than physical controls; check DSG fluid history.
Safety recalls
Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Audi A6 Avant, or your exact vehicle, has any outstanding recalls on the official DVSA service.
Check on GOV.UKOpens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.
Theft risk
A general indicator from UK 2025 theft data and this car’s characteristics — not a prediction for any one vehicle.
Whole-car theft
Higher
Higher-value cars like this are relay-theft targets — keyless entry can be exploited from the driveway in under a minute.
Parts theft
Higher
Hybrid versions are a catalytic-converter target — a hybrid cat is rich in precious metals and can be cut out in about a minute.
Worth doing
- Keep keys in a Faraday pouch and away from the front door to block relay attacks.
- A catalytic-converter guard or forensic marking makes a hybrid far less appealing to cut.
- A visible steering lock is a cheap, strong deterrent on a frequently-targeted car.
Clean-air zones
Whether driving a Audi A6 Avant into a UK clean-air zone will cost you anything. Rules use the same Euro standard across most zones — petrol from 2006 and diesel from 2015 onwards are exempt; pure electric is always exempt.
Charging zones for cars
| City | Area | Daily charge | Likely outcome |
|---|---|---|---|
| London | All of Greater London (within the M25) | £12.50 | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |

| Bristol | City centre and part of the Portway | £9.00 | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |

Servicing & the dealer network

Large network
Premium mainstream
Network size relative to the UK's largest (Audi is 2.6% of all franchised outlets)
Servicing, parts and warranty work are easy to find UK-wide, and most independent garages know the brand well — which keeps maintenance competitive.
For context, the UK has roughly 4,500 franchised car-dealer outlets in total, plus about 15,500 independent garages.
Approximate figures, curated from public UK industry sources (NFDA, Car Dealer Magazine). Franchised networks shrink year on year — these indicate network size, not an exact count.

Common questions
Audi A6 Avant, answered from the data
- How much does a used Audi A6 Avant cost?
- A 2023 Audi A6 Avant with around 28,479 miles is worth roughly £29,900 today (typical range £25,800–£34,000). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.
- How quickly does the Audi A6 Avant depreciate?
- A new Audi A6 Avant typically loses about 40% of its value over the first three years, then depreciates more slowly. Buying at three to five years old avoids the steepest part of the curve.
- What insurance group is the Audi A6 Avant?
- The Audi A6 Avant sits in insurance group 31 of 50 — the more expensive end of the scale. Exact premiums depend on the trim (some versions sit a few groups higher or lower), your age, postcode and no-claims history.
- What goes wrong on a used Audi A6 Avant?
- The parts most often recorded at MOT on the Audi A6 Avant are: suspension (typically around over 100k miles, £150-£450 to put right); lighting & signalling (typically around over 100k miles, £15-£120 to put right); tyres & wheels (typically around 60k-100k miles, £80-£500 to put right). A full service history and a recent MOT with no advisories are the best protection.
- What does the Audi A6 Avant cost to run?
- Expect around 51 mpg combined on the 40 TDI 2.0, £200 a year in road tax, about £290 for a standard annual service. The full cost-of-ownership table above breaks this down per year and per mile for the exact year and mileage you choose.
- Is the Audi A6 Avant ULEZ compliant?
- Whether a Audi A6 Avant is ULEZ compliant depends on its engine and registration date: petrol from 2006 and diesel from September 2015 generally qualify, and electric versions are always exempt.
