2013 Audi A6 S Line TDI 2.0L Heavy oil · CNZ 511

The latest MOT test on 19 March 2026 resulted in a pass with no recorded defects, indicating the vehicle met the minimum roadworthiness standards at that time. However, the history shows two failed tests in close succession—8 March 2026 and 21 January 2024—both without listed defects, which suggests these may have been administrative or minor retest failures rather than mechanical issues. The overall trend appears stable, with three consecutive passes since April 2025, but the lack of detailed defect or advisory notes makes it difficult to assess long-term maintenance consistency. At 147,709 miles over 13 years, the annual average of approximately 11,362 miles is typical for a vehicle of this age and suggests regular, moderate use rather than prolonged periods of inactivity or excessive wear. This mileage profile implies that consumables such as tyres, brakes, and suspension components are likely to have undergone natural wear, but not to the extreme levels seen in high-mileage commercial or fleet vehicles. The absence of rapid mileage accumulation reduces the risk of premature drivetrain or engine fatigue, though age-related degradation remains a consideration. Given the clean MOT history, a prospective buyer should focus on age-related inspections. Check the condition of the tyre sidewalls for cracking or perishing, as rubber degrades over time regardless of mileage, and verify the 12V battery health, as original units often fail after 5-7 years. Examine the brake discs for surface corrosion or uneven wear, which can indicate binding calipers or infrequent use, and listen for suspension clunks or knocks over rough surfaces, which may reveal worn bushes or shock absorbers. Additionally, inspect for underseal corrosion, particularly around the sills, jacking points, and subframe, as structural integrity is critical for a vehicle of this age. Finally, confirm the service history to ensure time-based fluid changes have been adhered to, including engine oil, coolant, and differential or transmission fluids, as these degrade with age even if mileage is moderate. Test the vehicle’s cold start behaviour and listen for excessive diesel knock or turbocharger whine, which could indicate wear in the TDI engine. A thorough inspection of the exhaust system for leaks, corrosion, or soot buildup is also advisable, as these are common issues in older diesel models and can affect both emissions compliance and performance.
