Recalls that may affect cars built around 2004
3 of the Audi A4’s 33 recalls in DVSA’s records cover cars built during 2004. 1 has no build dates, so could apply to any year.
The 2004 on this page is the year of first registration, not the year the car was built. A car first registered early in 2004 may have been built in 2003, and recalls apply to particular build dates and VINs, so check the recalls either side too.
| Launched | Concern | Built | Vehicles |
|---|---|---|---|
| 4 Apr 2024 | Replacing Takata passenger airbag | 4 Oct 2004 to 18 Apr 2008 | 90,946 |
| 1 Feb 2023 | If a front airbag is deployed it is possible that the gas generator housing in which the propellant is generated may burst on vehicles manufactured within a limited period. | 12 Oct 2004 to 4 Apr 2008 | 39 (all models) |
| 1 Mar 2005 | Bolts of the tandem fuel pump cover may break | 1 Mar 2004 to 31 Aug 2004 | 14,820 (all models) |

Data sources and methodology
| Figures | Source | Period | Records | Updated |
|---|---|---|---|---|
| MOT results and mileage | Anonymised MOT tests and results Driver and Vehicle Standards Agency Derived statistics UK Motoring | 2025 | 4,998 MOT tests of 2004 Audi A4 cars | 15 September 2026 |
| Cars on the record | Vehicle licensing statistics Department for Transport | End of 2025 | 7,757 cars still on the record (licensed or SORN) | 15 September 2026 |
- MOT figures cover normal tests in Great Britain in 2025 of Audi A4 cars first registered in 2004; retests are excluded. “All cars” means every car we match to a model, first registered in 2004.
- Year of first registration is DVSA’s first-use date: when the car was first registered, in the UK or abroad.
- Defects and advisories are DVSA’s descriptions made readable. Where on the car a defect was found (side, front or rear) is ignored, so the same fault on any wheel counts once per test.
- Mileage is the odometer reading at each car’s latest normal MOT of the year, as recorded by the tester. A few readings are in kilometres or mistyped; percentiles are not thrown by a handful of outliers.
- Cars on the record come from DfT table VEH0124 and cover the United Kingdom, including Northern Ireland; MOT figures cover Great Britain only.
- 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.
