Audi S4 MOT failures
Tyres is the most common reason a Audi S4 fails its MOT, appearing on 32.9% of failed tests. A failed test can have defects in more than one category, so shares add up to more than 100%. 4.7% of Audi S4 tests found at least one dangerous defect, against 7.3% for all cars.

Audi S4 fuel economy and CO2
The Vehicle Certification Agency’s new car data lists the Audi S4 from 2003 to 2010. On the NEDC test (listings 2003 to 2010), official combined fuel economy for its petrol versions ranges from 20.3 to 23.5 mpg, with CO2 of 286 to 334 g/km.
| Engine and fuel | Combined mpg | CO2 g/km | Listed | Euro standard | Versions |

- 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.
- 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 “S Series”, “Audi 'S' Series”. How we use VCA’s figures.
Audi S4 safety recalls
We found no recalls for the Audi S4 in DVSA’s records since 1992. That does not mean none apply: DVSA sometimes records a recall under a range or chassis name we cannot match to a model. Check a specific car on GOV.UK’s vehicle recall check.
A recall applies to cars built on particular dates or with particular VINs, not to every Audi S4. 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.
