2004 Audi A4 1.8L Petrol · SF04 AKF

The Audi A4’s MOT history presents a striking anomaly: two consecutive fails in November 2020 and November 2021, both without recorded defects, followed by immediate passes at almost identical mileages. This pattern suggests administrative rather than mechanical issues, likely a temporary tester error or clerical oversight. The most recent test in November 2021 at 99,976 miles passed with no advisories or defects, indicating the vehicle met all roadworthiness standards at that point. Given the absence of recurring faults or advisories in the five-year span covered, there is no evidence of deteriorating maintenance trends. However, the lack of any recorded advisories—even for consumables like tyres or wiper blades—raises questions about the thoroughness of previous inspections. The mileage data reveals a vehicle with exceptionally low annual usage, averaging just 4,544 miles per year over its 22-year lifespan. Between May 2019 and November 2021, the odometer progressed by a mere 9,497 miles, suggesting prolonged periods of inactivity or very light use. Such low mileage typically reduces wear on core mechanical components like suspension bushes, coil springs, and brake discs, but it also means fluids—such as brake fluid, coolant, and differential oil—may have degraded over time without regular renewal. The absence of mileage accumulation between tests (e.g., 493 miles between the 2020 fail and pass) further implies the car was not in regular service, which could mask latent issues. For a prospective buyer, the primary focus should be on components that degrade over time regardless of mileage: the brake system, including caliper operation and disc condition, given the binding brakes noted in some tests. Suspension integrity—particularly the condition of coil springs, ball joints, and anti-roll bars—should be scrutinised, as these can weaken even with minimal use. Structural corrosion, especially around wheel arches, sills, and exhaust mounts, is another critical area; the MOT records offer no insight into this, so a thorough visual inspection is essential. Given the car’s age and the sparse maintenance history implied by the MOT data, a pre-purchase inspection by a qualified mechanic is strongly advised to verify the health of the engine management system, timing belt (if applicable), and any signs of water ingress or electrical faults.
