Both cover the United Kingdom. Pass rate: first-time passes at normal MOT tests in Great
Britain in 2025; all cars: every car first registered the same year.

How we use engine sizes.
Audi A4 fuel economy and CO2
The Vehicle Certification Agency’s new car data lists the Audi A4 from 2000, when the data begins, to 2018. On the NEDC test (listings 2000 to 2018), official combined fuel economy for its petrol and diesel versions ranges from 25.0 to 74.3 mpg, with CO2 of 99 to 271 g/km.
Official NEDC figures by engine and fuel, listed 2000 to 2018
Official NEDC figures by engine and fuel, listed 2000 to 2018
Official figures from laboratory type-approval tests. VCA says they may not be achieved in
real-world driving, and should not be used to rank cars with similar figures.
VCA’s data has no Audi versions for 2019 to 2024, so the years listed may leave out years the Audi A4 was on sale.
Engine sizes are rounded to the nearest 0.1 litre. A version is one line in
VCA’s data (description, gearbox, engine and fuel), counted once however many years it was
listed.
Matched from VCA’s model names “A4 Saloon”, “A4 Avant”, “New A4 Saloon”, “New A4 Avant”. How we use VCA’s figures.
Audi A4 safety recalls
DVSA lists 33 safety recalls for the Audi A4 since 1992, the first in 1997. The most recent was launched on 8 August 2025.
Stop-drive TAKATA PSAN
Launched 8 August 2025DVSA recall R/2025/387Manufacturer ref. TKSD
Defect
Urgent Safety Warning – Do Not Drive Your Vehicle Affected vehicles were originally allocated to or used for an extended period of time in a region with a climate zone considered to as HIGH RISK. Certain front airbags contain an ageing inflator propellant that may explode when deployed due to long-term exposure to heat and humidity. If the airbag inflator explodes metal fragments may be ejected causing life-threatening or fatal injuries to anyone in the vehicle.
Remedy
Affected airbags will be be replaced. You can contact Audi's dedicated Takata Stop Drive helpline at 0113 526 9646 (MONDAY to FRIDAY 9:00AM to 5:00PM.
A recall applies to cars built on particular dates or with particular VINs, not to every Audi A4. The details come from manufacturers through DVSA, which says they may be delayed or
incomplete. To check a specific car, use GOV.UK’s vehicle recall check or ask the manufacturer or a
dealer. How we match recalls to models.
Figures cover Great Britain (England, Scotland and Wales). Northern Ireland is not included.
Licensed counts are vehicles with a current tax or exemption at the end of each year (or the latest quarter). SORN counts are shown separately.
First registrations count vehicles registered in Great Britain for the first time, including used imports.
Models are grouped by DVLA’s generic model name, so every generation and trim counts together.
MOT figures cover normal tests of cars aged three and over in 2025; retests are excluded. Age is rounded to the nearest year.
DVSA records the model name typed in at the test. We match those names to DVLA’s generic models, so a handful of tests may be counted under a close relative.
