2013 Audi A4 2.0L Diesel · LT13 MLF

The latest MOT test conducted on 2026-08-19 resulted in a passing grade, though the vehicle carries several persistent advisories that warrant careful attention. Over the past three years, the MOT history shows a pattern of recurring issues rather than a clear improvement or deterioration. While the 2024 and 2023 tests were clean aside from minor suspension wear advisories, the 2025 failure highlighted a critical failure of the near-side front outer drive shaft constant velocity (CV) joint boot, which was deemed unsafe due to its compromised integrity. This failure underscores a need for proactive maintenance, particularly given the vehicle’s age and accumulated mileage, as CV joint issues often progress silently until they lead to drivetrain damage or catastrophic failure. The consistent advisories on suspension arm bush wear and oil leaks suggest underlying wear that, if left unaddressed, could lead to further structural compromise or alignment issues. The recorded mileage of 120,936 miles for a vehicle aged approximately 13 years represents a reasonable annual usage rate of around 9,303 miles per year, which is typical for a car of this age and usage profile. Such mileage accumulation is consistent with moderate daily use, though it does not necessarily indicate excessive wear beyond what is expected for its age. However, the presence of a CV joint failure in 2025—particularly at this mileage—could imply either a history of aggressive driving or a pre-existing condition that was not fully mitigated by previous servicing. The gaps between MOT tests, particularly the extended period between 2020 and 2021, suggest the vehicle may have been stored for extended periods, which can exacerbate issues such as corrosion from standing, fluid degradation, and wear from lack of use. For a 13-year-old car, the suspension and drivetrain components are particularly susceptible to deterioration when combined with high mileage, so any signs of excessive movement in joints or leaks should be treated as red flags. Given the recurring advisories and the critical nature of the CV joint failure, the prospective buyer should prioritise a thorough mechanical inspection before purchase. Focus on the front suspension arms and CV joints, checking for any signs of excessive play, binding, or unusual noises during acceleration and cornering. Listen for clunking or rattling in the front suspension, particularly when driving over bumps or at low speeds, as this may indicate worn suspension bushes or arm pins. The oil leak advisories warrant inspection of the oil pan, valve cover, and engine mounts for signs of fluid pooling or damage, as these areas are common leak sources. Additionally, verify the condition of the brake discs and pads, noting any signs of warping, scoring, or uneven wear, which could suggest brake system issues or previous overheating. For the CV joint, inspect the boot for any signs of cracking or tears, and check for grease leaks or excessive play in the joint itself, as these are clear indicators of failure progression. Beyond mechanical checks, the buyer should conduct a comprehensive inspection of the vehicle’s external and internal components. Given the age and mileage, the tyres should be thoroughly examined for sidewall cracking or perishing, which can weaken the structure and reduce safety. The battery should be tested for voltage and corrosion, as older vehicles are more prone to battery failure from prolonged inactivity or age-related degradation. Fluid levels and condition should be checked—particularly the brake fluid, which can degrade over time and compromise braking performance—and ensure all fluids are topped up to manufacturer specifications. Finally, the buyer should verify the service history for the CV joint replacement and any suspension or drivetrain work, as this will provide insight into the vehicle’s maintenance record and help mitigate potential future costs. If the CV joint has been replaced recently, the buyer should confirm the work was done by a qualified technician and that the boot was properly sealed. In summary, while the MOT history shows the vehicle is roadworthy, the presence of critical advisories and a history of wear-related issues demands diligent due diligence to avoid costly repairs.
