2021 Audi Q5 S Line 50 Tfsi E Quattro SA 2.0L Hybrid electric (clean) · WN51 BAT

The most recent DVSA MOT test conducted on 14 October 2025 resulted in a pass with no defects or advisories recorded, indicating that the vehicle satisfied all statutory roadworthiness requirements at the time of examination. With only one prior test entry on file, dated 7 October 2024, which carried a single advisory regarding front tyre wear, the overall maintenance trend can be characterised as broadly stable and reassuringly clean. The absence of any advisories on the latest test demonstrates that the previous tyre wear concern has been appropriately addressed, and there is no evidence of recurring mechanical, structural, or emissions-related issues from the official DVSA record. For a prospective buyer, this represents a favourable starting point, although it should be noted that an MOT pass is a minimum legal threshold rather than a comprehensive mechanical inspection, and deeper due diligence remains advisable given the vehicle's premium specification and complex plug-in hybrid powertrain. Recorded mileage stands at 28,717 miles over approximately five years of age, equating to an average annual accumulation of around 5,743 miles. This figure is notably below the typical mileage for a vehicle of this type and age, suggesting either genuinely light usage, a predominantly urban driving pattern, or extended periods of standing between uses. While low mileage reduces wear on major drivetrain components such as the engine, transmission, and clutch assembly, it introduces its own set of considerations. Irregular or infrequent use can accelerate degradation of rubber and polymer components through age rather than use, and prolonged standing can lead to brake disc corrosion, calliper binding, and fluid degradation from calendar exposure rather than mechanical cycling. Given the relatively low annual mileage and the clean MOT history, physical inspection should focus on age-related deterioration rather than wear patterns. Tyre sidewalls should be carefully examined for perishing, cracking, or ozone damage, as tyres older than five years may exhibit hardened compound and reduced grip even if tread depth remains adequate. The 12-volt auxiliary battery, which manages the vehicle's electronic control systems and hybrid system wake-up functions, is susceptible to sulphation and premature failure when the vehicle is left standing for extended periods, so a battery health check or voltage test is strongly recommended. Brake discs should be inspected for surface rust, though light corrosion is normal and typically clears with use; however, more severe pitting or seizing of the calliper slide pins may indicate standing-induced binding that warrants disassembly and lubrication. Brake fluid is hygroscopic and degrades over time regardless of mileage, typically requiring replacement every two to three years to prevent moisture ingress and reduced boiling points, so verification of the last fluid change date is worthwhile. On a test drive, particular attention should be paid to the transition between the electric and combustion powertrains, as the 50 TFSI e quattro system relies on seamless coordination between the 2.0-litre turbocharged petrol engine, the electric motor, and the lithium-ion battery pack. Any warning messages relating to hybrid system function, unexpected engine running when stationary, or inconsistent regenerative braking should be investigated promptly at an Audi specialist or via the vehicle's onboard diagnostic readout. Suspension bushes, anti-roll bar links, and coil springs should be assessed for any knocking, clonking, or uneven tyre wear patterns indicative of perished components, even though these are not yet reflected on the MOT record. The quattro drivetrain, transfer box, and rear differential should be checked for fluid condition and any signs of leaks, particularly around the oil seals. Verifying that the vehicle has been serviced in accordance with Audi's variable service schedule, with stamps or digital records confirming timely replacement of engine oil, transmission fluid, spark plugs, and the plug-in hybrid system's coolant and battery conditioning systems, will provide further confidence that this low-mileage example has been correctly maintained.
