2004 Audi A4 2.5L Diesel · CW04 AKK

The 2004 Audi A4’s most recent MOT tests, conducted just under two years ago on 2024-09-05, reveal a concerning pattern of repeated failures despite identical mileage readings of 137,031 miles. Both tests in September 2022 were marked as failed without recorded defects, which is unusual—this suggests either a technical error in the system or that the vehicle was not actually tested that month. The preceding tests in August 2021, at 135,311 miles, also show the same anomaly: a pass and a fail at the same mileage. Without visible defects or advisories, this inconsistency undermines confidence in the vehicle’s true condition. The lack of any advisories or recurring faults in the official record does not imply neglect; rather, it raises questions about whether the vehicle was ever properly assessed during these periods. The recorded mileage of 137,031 miles over 22 years equates to an average of approximately 6,229 miles per year, which is typical for a vehicle of this age. There are no significant gaps or spikes in mileage between tests, as the intervals are consistent at around one year. However, the repeated failures at identical mileage readings in 2021 and 2022 are notable outliers. This suggests either a systemic issue with the MOT testing process for this vehicle or that the tests were not conducted as scheduled. Without additional service records, it is impossible to determine whether the vehicle has been maintained at the expected intervals for its age, but the lack of advisories in the MOT history implies no major mechanical failures were documented. Given the lack of specific defects in the MOT record, a buyer should prioritise an independent inspection of high-wear components that are not routinely captured in MOT tests. Focus on the suspension system—particularly the condition of coil springs, bushes, and dampers—given the vehicle’s age, as these are prone to fatigue and corrosion. The brakes, including calipers, pads, and discs, should be checked for uneven wear or binding, especially if the vehicle has experienced rapid acceleration or braking cycles. Structural integrity is another critical area; inspect the underbody for corrosion around the sills, wheel arches, and exhaust system, as these areas are common failure points for vehicles of this era. The absence of advisories does not guarantee these components are sound, so a thorough mechanical examination is essential before purchase.
