2002 Audi A4 1.9L Diesel · ML02 YTS

The most recent DVSA test on 2 May 2025 resulted in a PASS, but only after a failure just eight days earlier on 24 April 2025, which is a useful signal of the vehicle's overall maintenance trajectory. The earlier failure cited an excessively worn nearside front upper suspension arm ball joint and an illegible registration plate, while the subsequent pass picked up a cluster of advisories around rear suspension component corrosion and an oil leak not deemed excessive. Looking back through the available records, there is a clear and consistent pattern of structural and suspension-related advisories year on year, with the rear sub-frame, rear coil springs, and rear suspension arms all flagged at multiple tests between 2022 and 2025. Combined with major defects recorded at the 2023 and 2022 tests, including a binding nearside front service brake, ABS warning lamp illumination, an excessively worn track rod end ball joint, and a rough front wheel bearing, the trajectory suggests a vehicle whose chassis and running gear are progressively deteriorating rather than being actively maintained. A prospective buyer should treat the repeated advisories as early warnings of component replacements that will be required in the near term. With 193,835 miles recorded over approximately 24 years, this Audi A4 has covered around 8,076 miles per year on average, which is broadly typical for its age and not suggestive of either long-term standing or exceptionally heavy use. That said, given the accumulation of corrosion advisories on structural and suspension components, the practical implication is that the vehicle has clearly been exposed to the typical UK winter road salt environment throughout its life, accelerating oxidation of ferrous components even though the annual mileage is modest. The mileage is now well into the territory where age-related wear of ancillary systems, rubber components, and electrical items becomes as significant as pure distance-based wear, and the recorded oil leak advisories across every test in this dataset suggest a long-standing seep that warrants monitoring rather than immediate panic, but should not be ignored. The most pressing area for buyer due diligence is the suspension and steering system. The nearside front upper suspension arm ball joint has now failed twice within three years, in 2023 and again in 2025, which indicates that the underlying bushes or arms may be wearing prematurely or that a previous repair was not fully comprehensive. On a test drive, listen for clonks or knocks from the front end over speed humps and uneven surfaces, pay particular attention to any vagueness in steering response or uneven tyre wear across the front axle, and inspect the inner edges of the front tyres for feathering. The track rod end ball joint failures in 2022 and 2023 further support a thorough check of steering geometry; any wandering at speed or uneven tyre wear would be telltale signs of further wear. The binding nearside front service brake reported in 2024 is also worth a focused inspection, as a caliper that has seized can return to function temporarily only to bind again, leading to uneven braking, pulling to one side under braking, or a brake disc that runs hot after use. Carefully feel for heat at the front wheels immediately after a drive, and check for a glazed or discoloured appearance on the nearside front disc. Beyond the chassis, the recurring advisories on rear coil spring corrosion and sub-frame corrosion across multiple consecutive tests indicate that these areas are steadily oxidising and will likely fail an MOT outright within one or two further tests if left untreated. It would be prudent to have the vehicle raised on a ramp so the sills, rear sub-frame mounting points, and suspension arm pick-up points can be physically probed, since much of the structure is obscured by under trays as the MOT record itself notes. The persistent but non-excessive oil leak should be identified by source before purchase, as even minor leaks from the cam chain area, valve cover gasket, or sump on these engines can escalate quickly. Finally, given the vehicle's age, a buyer should also verify the condition of age-sensitive items not always captured in MOT data, including the 12V battery, which is well beyond its typical service life, brake fluid which degrades hygroscopically over time regardless of mileage, coolant strength to confirm corrosion protection in the cooling system, and the condition of all tyres for sidewall perishing and cracking even where tread depth remains legal. Confirmation of a full service history with stamps at appropriate intervals will be especially important on a vehicle of this age and mileage.
