2004 Audi A4 2.5L Diesel · ND04 EVU

The 2004 Audi A4 presents a concerning maintenance gap, with the most recent MOT test dating back to January 2022—over four years ago—and the vehicle failing to pass on its first attempt that same month. Both tests at 143,932 and 154,301 miles were recorded on consecutive days, yet neither revealed any defects, suggesting either an unusually clean vehicle for its age or a tester error. The absence of advisories or defects in the 2019 test at 140,801 miles further implies that if issues exist, they are either latent or have developed since. Without a single advisory or failure noted in the last seven years, the lack of documented maintenance raises questions about whether the car has been driven regularly or simply neglected entirely. The stability of the test outcomes is misleading; a vehicle this age should show some wear in official records, particularly given its 154,301 miles. The mileage accumulation of roughly 7,014 miles per year aligns with typical usage for a 22-year-old car, but the clustering of tests in January 2021 and 2022—just 132 miles apart—is unusual and may indicate a deliberate attempt to meet MOT deadlines without addressing underlying wear. The 2019 test at 140,801 miles suggests the car sat unused for nearly two years before the next inspection, a pattern that could accelerate corrosion or seal degradation. No rapid mileage spikes appear, but the prolonged gap since 2022 means critical components—such as brake fluid, suspension bushes, and tyre condition—could now be beyond their service intervals. The absence of recorded mileage between tests also prevents any assessment of how the vehicle was driven during those periods. Given the clean but outdated MOT history, a buyer should prioritise a thorough inspection of structural integrity, particularly around wheel arches, sills, and suspension mounts, where corrosion often begins unseen. The rear brakes should be checked for binding or uneven wear, as the 2022 failures without defects may mask underlying issues like seized calipers or warped discs. Suspension components—coil springs, anti-roll bars, and bushings—will likely need replacement, given their typical lifespan and the car’s age. Tyres, even if tread appears sufficient, should be measured for uneven wear or internal damage, while the exhaust system must be verified for leaks or rust-induced fractures. The lack of documented maintenance means no service history exists to confirm oil changes, brake fluid replacements, or timing belt integrity, all of which are critical for a vehicle of this vintage.
