2005 Audi A4 2.0L Diesel · YD55 PZB

The vehicle is currently roadworthy but the maintenance history indicates a worsening trend regarding fluid containment integrity. While it passed the February 2026 test at 194,196 miles, this result followed a significant failure in October 2025. That failure revealed high-priority issues including an excessive oil leak, a fuel system leak, and a failing parking brake system. Although the oil leak was noted as non-excessive in the most recent test, the persistence of fluid loss across multiple years suggests that engine seals are steadily degrading rather than being professionally repaired. At 194,196 miles over 21 years, the car averages approximately 9,247 miles per year, which is consistent with typical UK usage. However, the data shows a sharp spike in usage between October 2024 and October 2025, where the vehicle covered 15,148 miles in just twelve months. This rapid accumulation has placed significant stress on the aging components, evidenced by the sudden appearance of multiple suspension and braking faults in the subsequent tests. The interval between tests remains consistent, but the mechanical demand is accelerating. A buyer must conduct a thorough physical inspection of the engine bay and underbody to assess the severity of the recurring oil and fuel leaks. The record flags worn bushes on the nearside front upper suspension arms and anti-roll bar linkages, indicating the front suspension geometry is nearing the end of its service life. The misted offside rear shock absorber is also an early sign of failure that will require replacement soon. Given the previous failures for ABS and SRS warning lamps, the buyer should verify that these electronic systems have been properly diagnosed and are not merely cleared of a hidden fault.
