OY04 BKF MOT History
Interpretation generated from the recorded test data above — not an official DVSA statement and not a substitute for an independent inspection.
5 MOT tests are recorded for this 2004 Audi A6 (OY04 BKF) between June 2024 and June 2026.
The record contains 3 passes and 2 failures.
The most recent test on 19 June 2026 was a pass, although the earlier record includes 2 failures that buyers may want to investigate.
Across all tests, the most frequently flagged areas are: Lighting (18 issues), Bodywork (8 issues), Tyres (7 issues), Suspension (6 issues), Exhaust & Emissions (3 issues). Repeated mentions in one area can indicate an ongoing pattern worth checking in person.
In total 43 advisory notices are recorded. Advisories flag items that passed but may need attention before the next test; they are not evidence of how well the vehicle has been serviced.
Recorded failure items include: “Nearside Rear Tyre has a cut in excess of the requirements deep enough to reach the ply or cords (5.2.3 (d) (i))”; “Offside Front Headlamp aim projected beam image is obviously incorrect (4.1.2 (c))”; “Nearside Front Headlamp aim projected beam image is obviously incorrect (4.1.2 (c))”.

Our Verdict
Avoid this 2004 Audi A6 due to recurring mechanical issues, high mileage, and significant corrosion risks. The vehicle shows persistent problems with suspension, exhaust, and tyre integrity that could lead to costly repairs.
Prioritise a full mechanical inspection of the suspension system, exhaust assembly, and corrosion-prone areas like sills and sub-frames. Verify service history for repairs related to the 5.3.4 (a) (i) suspension bush issues and check for documented fixes to the 6.1.2 (a) exhaust leaks. Negotiate aggressively given the high risk of hidden repairs. Avoid if the buyer lacks mechanical expertise or budget for major work.
Petrol fuel economy is likely poor for a 2004 3.1L engine, with estimated 30-35 mpg. Tax would be £225 annually (2026 rates for 2004 models). Insurance group likely falls in 15-20, costing £1,000-£1,500 yearly. Major repairs to suspension, exhaust, and tyres could exceed £1,500. Annual running costs probably range £2,500-£3,500.
Thoroughly check suspension arms (5.3.4 (a) (i) issues recurring since 2024), exhaust system integrity (6.1.2 (a) leaks), and corrosion in sills/sub-frames (5.3.3 (b) (i)). Inspect tyres for cracks/cuts (5.2.3 (d) (ii)) and headlight alignment (4.1.2 (c)). Look for signs of repeated oil leaks (8.4.1 (a) (i)) and verify if body corrosion has progressed beyond 'not excessive' reports.
This 2004 Audi A6 has accumulated 102,434 miles over 22 years, exceeding typical mileage for its age. The MOT history reveals repeated suspension bush wear, exhaust leaks, and corrosion issues, with a 2026 MOT failure highlighting critical tyre and headlight problems. While the 3.1L petrol engine is robust, the vehicle's age and maintenance record suggest poor long-term value.
No aggregate data available for AUDI A6, but this vehicle's history shows frequent mechanical and corrosion issues typical of older luxury saloons.
