2017 Audi A4 2.0L Diesel · BW66 XCL

The most recent MOT carried out on 21 January 2026 returned a pass with no recorded defects, continuing an uninterrupted series of clean passes dating back to the first test in January 2020. This unblemished record indicates a consistently stable maintenance regime, with no apparent deterioration in the vehicle’s safety‑critical systems over the six‑year period. The absence of advisories or failures suggests that routine servicing and any required component replacements have been performed in a timely manner. At nine years old the Audi A4 has logged only 16 035 miles, an average of roughly 1 800 miles per annum. Such low annual usage is well below the typical UK average and often points to periods of limited running or extended storage. While reduced mileage lessens wear on engine, transmission and brake components, it also raises the likelihood of age‑related degradation of rubber and polymer parts, such as tyre sidewalls, suspension bushes, and seals, which can deteriorate even when the car is not being driven. Prospective buyers should give particular attention to tyre condition, checking the depth of the tread and, more importantly, the age of the tyres by inspecting the DOT code on the sidewall; tyres older than six years may have become brittle irrespective of mileage and should be evaluated for cracking or hardening. The battery, likely approaching a decade in service, should be tested for cranking voltage and examined for any signs of electrolyte leakage or terminal corrosion, as prolonged inactivity can accelerate loss of capacity. Since the vehicle has spent considerable time stationary, inspect the under‑carriage and wheel arches for any signs of surface rust or corrosion, especially around suspension mounting points and brake caliper pins, and verify that the brake discs are free of heavy pitting or rust that could cause uneven pad wear. Finally, confirm that all scheduled fluid changes have been observed by reviewing the service book or receipts: engine oil, coolant, brake fluid and gearbox oil typically require replacement on a time or mileage basis, and neglect can lead to seal shrinkage, reduced lubrication and eventual component wear. Examine the condition of the suspension bushes and mounts for any looseness, creaking or uneven tyre wear that could indicate early degradation. A thorough visual inspection of hoses, belts and the exhaust system for cracks, leaks or corrosion, coupled with a test drive listening for clunks, vibrations or brake shudder, will provide a comprehensive picture of the car’s mechanical health before committing to purchase.
