2021 Audi Q5 S LN ED1 40TDI Mhev Quat SA 2.0L Diesel · DX71 SHJ

The 2021 Audi Q5 40TDI with 51,822 recorded miles has a clean MOT history over the past three years, with all tests conducted between October 2024 and July 2025 passing without recorded defects. The consistent passing trend indicates a stable maintenance regime, though the absence of advisories or failures does not guarantee absolute freedom from underlying wear or latent issues. The lack of repeat failures suggests that the vehicle has been serviced according to manufacturer recommendations, but the absence of specific defect codes means no further details on particular component health are available. For a buyer, this record is reassuring but should be complemented by a thorough pre-purchase inspection to identify any subtle signs of wear that might not have surfaced in the MOT. The mileage of 51,822 miles for a vehicle of this age represents a reasonable annual usage rate of approximately 10,364 miles, which aligns with typical driving patterns for a car of this class. Such usage is unlikely to have accelerated wear beyond normal expectations unless there were periods of prolonged idling or heavy load carriage, which would have been reflected in higher mileage accumulation. However, the fact that the vehicle has not accumulated significantly more miles over the past five years suggests it has either been used sparingly or driven in a manner that avoids excessive wear. This could imply standing periods, particularly if the vehicle is used in a climate where it is frequently parked outdoors without protection. Buyers should be aware that lower mileage can sometimes mask issues such as corrosion from prolonged exposure to moisture, particularly in the wheel arches, undercarriage, and around the fuel tank and exhaust system. Given the clean MOT history and the vehicle’s age and mileage, the most critical areas for inspection during a pre-purchase examination should focus on signs of age-related degradation and potential standing-related corrosion. First, examine the tyres for sidewall cracking or perishing, which can occur over time even with low mileage, especially if the vehicle has been stored in a damp or extreme environment. Check the tread depth and look for uneven wear patterns, which could indicate misalignment, suspension issues, or poor alignment service history. The brake system should be inspected for signs of corrosion on the discs, particularly if the vehicle has been stationary for extended periods, as this can lead to binding calipers or reduced braking efficiency. Listen for any unusual noises during a test drive, such as grinding when braking, which may signal worn brake pads or warped discs, or clunking from the suspension, which could indicate worn suspension bushes or damaged coil springs. For fluid servicing, the engine oil and transmission fluid should be checked for time-based degradation, as these fluids can break down over time regardless of mileage. Given the vehicle’s age, the 12V battery should be tested for voltage and capacity, as older batteries can fail due to prolonged disuse or environmental factors. The exhaust emissions system should be visually inspected for leaks or corrosion, and the catalytic converter’s function can be assessed by listening for unusual noises or checking for backpressure during acceleration. Finally, verify that the service book is up to date, particularly for the timing belt replacement, which for this engine model is typically recommended at around 100,000 miles or every five years, whichever comes first. If the vehicle has been used in a region with high salt content or moisture exposure, additional attention should be paid to the undercarriage for signs of rust progression, as this can compromise structural integrity over time.
