2015 Audi A4 2.0L Diesel · WM15 LFD

The most recent DVSA examination on 25 June 2026 resulted in a pass, although a minor defect was recorded in respect of the offside front outer drive shaft constant velocity boot being severely deteriorated. This is a recurring item, having also been flagged at the previous test in July 2024, indicating that the component has been left without attention for a considerable period. While the advisory did not escalate to a failure, the duplicated record over consecutive tests suggests the boot has split or perished to the point where grease expulsion and eventual joint contamination are likely. The remainder of the test history is broadly stable, with clean passes recorded in 2025, 2023, 2021 and 2018, and the only advisories relating to tyre wear and underbody/engine cover fitment in earlier years. There is no evidence of escalating structural, braking or emissions concerns, and the overall maintenance trend appears stable rather than deteriorating, provided the CV boot defect is now rectified. With a recorded mileage of 129,106 miles over approximately 11 years, the vehicle has covered an average of around 11,737 miles annually, which is broadly typical for its age and segment. The MOT records suggest consistent usage rather than long periods of standing, and the mileage progression between tests appears regular without any suspicious gaps that might indicate clocking or extended inactivity. Consistent annual mileage of this nature is favourable, as it tends to keep the drivetrain, brakes and suspension working within their intended operating parameters, reducing the likelihood of seizing components, fluid degradation from disuse, and flat spots on tyres. However, the cumulative figure still places the vehicle in a higher wear bracket, so component lifespans for items such as clutch, dual mass flywheel (depending on transmission), turbocharger and suspension bushes should be considered. The recurring CV boot defect on the offside front driveshaft warrants close physical inspection prior to purchase. A deteriorated or split boot will allow grease to escape and permit water and debris ingress into the joint, accelerating wear of the constant velocity assembly itself. On a test drive, listen for a clicking or knocking noise from the front when turning at full lock, particularly under load, and feel for any vibration through the steering or drivetrain under acceleration. If the boot is visibly torn, greased, or has been inadequately repaired with a plastic sleeve or tape, factor in the cost of a replacement boot kit or, if the joint is already compromised, a complete driveshaft replacement. The earlier advisory relating to offside rear tyre wear in 2024 should also prompt a check of current wheel alignment and tracking, as uneven wear can indicate worn suspension bushes, a bent component, or simply the need for a four-wheel alignment following suspension work. Given the vehicle's age and mileage, even where MOT records are clean, several age-related items merit inspection. Check the sidewalls of all four tyres for cracking, perishing and bulging, as rubber deteriorates with calendar age regardless of tread depth, and confirm that the production date code on each tyre shows them to be within a reasonable service life. Inspect the brake discs for signs of corrosion, lipping at the outer edge, and check for any binding calipers by ensuring the vehicle rolls freely when released on a level surface. Verify the condition and age of the 12 volt battery, as a battery older than five to six years is likely to require replacement, particularly if the vehicle is used for short journeys. Finally, confirm the timing belt or cam belt replacement interval, as many Audi A4 petrol and diesel engines of this era require the belt and tensioners to be changed at fixed mileage or age intervals, and check that brake fluid, coolant and automatic transmission fluid (where applicable) have been refreshed in line with manufacturer schedules.
