2004 Audi A4 1.9L Diesel · SM54 LFD

The vehicle is currently roadworthy, but the maintenance trend shows a pattern of reactive component replacement rather than preventative care. In the most recent test on December 2025 at 159,189 miles, the Audi passed with lingering advisories for deteriorated rear brake hoses and oil misting on the offside front shock absorber. While the car has passed several consecutive tests, the persistence of these specific faults across multiple years indicates that components are only being addressed once they approach the point of failure. The mileage profile is consistent with the vehicle's twenty-two age, averaging approximately 7,236 miles per year. There is a steady accumulation of mileage between annual tests, such as the 713 miles recorded between November 2024 and December 2025, and the 708 miles recorded in the previous interval. This regular usage suggests the vehicle has not suffered from long periods of stagnation, which likely explains the age-related degradation of rubber components and hydraulic seals despite the relatively low total mileage count. A buyer must conduct a thorough inspection of the suspension and braking systems, as the history highlights chronic issues in these areas. The November 2022 failure revealed heavily worn upper suspension arm bushes and a serious fluid leak on the offside shock absorber, which have evolved into worn bushes on anti-roll bar linkages and misting shocks in subsequent years. The rear brake hoses have been flagged for deterioration since 2023; these should be visually inspected for cracking or bulging to prevent a sudden pressure loss. Furthermore, the 2022 report noted varied stages of corrosion across the chassis and braking components, necessitating a close look at the underbody to ensure structural integrity has not degraded beyond the noted advisories.
