2010 Audi A4 2.0L Diesel · YY10 OCV

The vehicle remains roadworthy, but the maintenance trend shows a worsening condition regarding suspension components and structural integrity. While the most recent test in August 2025 at 168,037 miles resulted in a pass, it introduced several new advisories that were absent in previous years. The transition from a clean record in 2022 to multiple failures in late 2024 indicates that the vehicle is entering a phase where age-related wear and corrosion are reaching their end-of-life failure points. At 168,037 miles over 16 years, the Audi has averaged approximately 10,500 miles per year, which aligns with typical national averages for a car of this age. The record shows consistent use, with roughly 8,000 miles covered between the October 2024 and August 2025 tests. However, the high mileage is clearly contributing to accelerated wear on rubber-based components, as evidenced by the repeated failures of suspension bushes and CV boots during the September 2024 inspection at 159,765 miles. A buyer must prioritise inspecting the rear sub-frame, as the tester noted corrosion in the mounting areas during both 2024 and 2025. While currently classified as not seriously weakened, structural rust on Audi sub-frames often progresses and becomes expensive to rectify if it spreads. The nearside rear shock absorber is now showing signs of oil leakage, and the worn bushes on both front lower shock absorbers suggest that the front suspension geometry is degrading. This will soon require significant investment to maintain vehicle handling and safety. The tyres and drive components also require immediate attention. The August 2025 test flagged perishing and cracking across all four tyres, suggesting the rubber is failing due to age rather than tread depth. The deteriorated nearside rear CV boot needs to be inspected for grease leakage; if the joint has been contaminated, the drive shaft will fail shortly, necessitating a much more costly assembly replacement.
