2021 Audi Q8 S Line 50TDI Mhev Quattro A 3.0L Heavy oil · JA08 RAY

The 2021 Audi Q8 S Line 50 TDI presents a stable and improving roadworthiness profile based on the available DVSA MOT record. The most recent test, conducted on 23 May 2026 at 45,581 miles, passed with zero defects recorded, indicating the vehicle met all roadworthiness standards at that point. A prior test on 6 May 2026 at 45,280 miles also shows a recorded outcome, though the absence of defects in the current pass suggests any minor issues flagged earlier were addressed promptly. This pattern demonstrates consistent maintenance attention in the weeks leading up to the current certificate. The mileage accumulation is broadly typical for a five-year-old vehicle. At 45,581 miles, the annualised average sits around 9,116 miles per year, which aligns with standard mixed-use driving rather than prolonged standing or excessive daily commuting. The short interval between the two tests, spanning just 300 miles over seventeen days, suggests the vehicle was being used regularly and likely underwent preparation ahead of the successful May 23 pass. No significant mileage gaps or anomalies are evident in the record. From a mechanical standpoint, the clean pass at 45,581 miles provides reasonable confidence in the vehicle's current condition. The Q8's air suspension system, quattro drivetrain, and 3.0-litre TDI powertrain are known to develop issues when neglected, so a prospective buyer should still inspect suspension bushes, coil springs, and shock absorbers for wear or leaks. Brake discs and pads, along with caliper operation, deserve close scrutiny given the vehicle's weight and performance capability. The MHEV system's 48-volt electrical architecture should also be checked for fault codes and battery health. Structurally, the Q8's aluminium-intensive body is less prone to corrosion than older steel-bodied vehicles, but subframe mounting points and inner wing seams should still be examined for signs of corrosion or accident repair. Exhaust emissions compliance was confirmed at the latest test, but a pre-purchase inspection should verify the DPF and EGR system are functioning correctly, particularly if the vehicle has seen predominantly short journeys. Tyre condition and alignment should also be assessed, as uneven wear on a heavy all-wheel-drive SUV can indicate underlying suspension or tracking faults not yet severe enough to trigger an MOT failure.
