2018 Audi Q5 S Line TDI Quattro S-A 2.0L Diesel · VRZ 9266

The most recent DVSA MOT test for this 2018 Audi Q5 S Line TDI Quattro S-A was conducted on 30 July 2026 and resulted in a pass with no defects or advisories recorded, indicating that the vehicle was considered roadworthy at the point of inspection. The previous recorded test on 10 August 2024 also returned a clean pass with no advisories, which suggests that the car has been maintained to a satisfactory standard in the immediate term. With no recurring failure items, advisories, or patterns of deterioration documented across the available DVSA history, the maintenance trend appears stable rather than worsening, although the sparsity of recorded tests means this stability cannot be conclusively confirmed over a longer period. Buyers should be aware that a clean MOT pass is a minimum legal standard and does not equate to a comprehensive mechanical inspection, particularly on a high-specification vehicle such as the Q5 with its complex quattro drivetrain and diesel emissions control systems. At 100,496 miles over approximately eight years, this Q5 is averaging around 12,500 miles per year, which is notably high for a vehicle of its class and age. This level of annual usage points to predominantly sustained driving, likely involving a mix of motorway and urban conditions, and implies greater wear on consumable and mechanical components than would be expected from a lower-mileage example. Higher mileage generally accelerates degradation of suspension bushes, coil springs, anti-roll bar links, drive belts, clutch assemblies, dual-mass flywheels, and turbocharger-related components. The mileage gap between the two recorded MOTs is roughly two years and approximately 20,000 miles, suggesting consistent usage rather than extended periods of standing, which is generally favourable for preventing issues such as brake disc corrosion, seized calipers, and stale fluids. However, prospective buyers should treat the 100,000-mile threshold as a milestone for inspecting the timing belt service interval, which on the TDI engine is typically due around this mileage depending on specification, alongside checks of the diesel particulate filter and AdBlue system. Given the high annual mileage, particular attention should be paid during a physical inspection to items that wear progressively with use. Tyres should be examined closely for tread depth, uneven wear patterns indicating suspension or tracking misalignment, and any sidewall perishing consistent with age. Brake discs and pads should be inspected for wear, lipping, and any signs of binding or uneven corrosion, as high-mileage vehicles commonly require disc refurbishment or replacement. The quattro drivetrain warrants scrutiny for any signs of rear differential oil leaks, propshaft balancing issues, or excessive transmission fluid degradation, while a test drive should reveal any clunks from the suspension over uneven surfaces, knocking from worn top mounts or anti-roll bar drop links, and any shudder or vibration through the steering wheel under braking that may suggest warped discs. Beyond mechanical wear, age-related deterioration remains a consideration on an eight-year-old vehicle regardless of mileage. The 12V battery should be load-tested, as batteries typically degrade after five to seven years and can cause erratic electronic behaviour in vehicles with high specification levels such as this S Line model. All fluids, including engine oil, coolant, brake fluid, and transmission fluid, should be checked for condition and service history, as brake fluid is hygroscopic and should be renewed every two to three years, while diesel fuel systems benefit from periodic AdBlue top-ups and injector servicing. Diesel-specific components, including the EGR valve, turbocharger actuator, and DPF, should be assessed for warning lights or restricted performance symptoms, and any dashboard warning lights should be investigated using a diagnostic scan tool prior to purchase. A comprehensive inspection by an Audi specialist or independent garage is strongly recommended to confirm the long-term mechanical integrity of this high-mileage Q5.
