Audi A4 Avant

The B9 Audi A4 Avant (2016-2024) is the understated executive estate - the load-lugging version of the A4 saloon, with one of the best cabins in the class and a usefully square boot. UK cars are diesel and mild-hybrid petrol, all quiet and frugal on a run. It's comfort-and-quality first rather than sporty, a sensible, classy alternative to a 3 Series Touring. As a used buy it's a refined, durable family estate that holds its value on badge strength.

Best age to buy — around 4 years

A 4-year-old example loses roughly £3,550 a year — under half the £8,750 a one-year-old sheds. The steepest drop is behind it.

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.

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.

MOT pass rate by age

A 3-year-old A4 Avant passes its MOT 71.4% of the time; by 20 years that has risen to 75.9%. The y-axis is zoomed to this model’s range so the trend is readable.

Reliability

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 diesel is the long-distance choice; the petrol suits lower-mileage use.
  • 02A square, practical boot and a beautifully built cabin are the estate's strong cards.
  • 03S tronic dual-clutch gearboxes want their fluid changed on schedule - check the service history.

Safety recalls

Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Audi A4 Avant, or your exact vehicle, has any outstanding recalls on the official DVSA service.

Check on GOV.UK

Opens 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 A4 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.

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.

Common questions

Audi A4 Avant, answered from the data

Is the Audi A4 Avant reliable?
The Audi A4 Avant scores 74/100 on Forecourt's MOT-based reliability measure. That is computed from 7,889 real DVSA MOT test results.
How much does a used Audi A4 Avant cost?
A 2023 Audi A4 Avant with around 34,830 miles is worth roughly £21,650 today (typical range £19,550–£23,750). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.
How quickly does the Audi A4 Avant depreciate?
A new Audi A4 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 A4 Avant?
The Audi A4 Avant sits in insurance group 30 of 50 — the middle 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 A4 Avant?
The most common age-related issues we track for the Audi A4 Avant are: tyres & wheels (typically around 30k-60k miles, £80-£500 to put right); suspension (typically around 30k-60k miles, £150-£450 to put right); brakes (typically around 30k-60k miles, £150-£500 to put right). A full service history and a recent MOT with no advisories are the best protection.
What does the Audi A4 Avant cost to run?
Expect around 47 mpg combined, £195 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.
