2015 Audi A4 2.0L Diesel · SS65 JJS

The vehicle most recently passed its MOT test on 16 April 2026 with no defects or advisories recorded, representing a clean bill of roadworthiness at the present time. Evaluating the trajectory of the recent test history, the maintenance trend appears broadly stable with isolated transient issues rather than a pattern of progressive deterioration. The April 2026 pass followed an August 2025 pass that carried only tyre-related advisories, which suggests that wear items were addressed at the intervening service. The two earlier failures, both in 2022 and 2023, related to separate, isolated mechanical faults, namely an engine management malfunction indicator lamp issue and a split constant velocity joint boot, both of which appear to have been rectified given subsequent passes. The recurrence of the CV boot failure in 2024 is a minor concern, as a second failure of a replacement boot within roughly twelve months may indicate either a substandard replacement component, a perished or incorrectly seated retaining clip, or damage caused by contact with a suspension or undertray element. Otherwise, the overarching pattern is one of satisfactory mechanical upkeep. With recorded mileage of 123,550 miles across approximately eleven years, the vehicle is accumulating at an average rate of around 11,232 miles per annum, which is broadly consistent with typical UK usage for a vehicle of this age and category. There are no conspicuous gaps in the recorded mileage between test entries, indicating fairly continuous use rather than extended periods of standing. This steady accumulation is generally positive from a corrosion and component-seizure perspective, as the mechanicals, seals, and brakes have remained in regular service, reducing the likelihood of seized calipers, rusted brake disc surfaces, or degraded fluid from inactivity. However, this mileage places the vehicle in the upper-middle bracket for an eleven-year-old Audi A4, meaning that higher-wear items such as suspension components, drivetrain mounts, and turbocharger-related items on the diesel or petrol engine will have already endured significant cumulative stress. The 2024 brake disc advisory, combined with the tyre wear advisories of 2024 and 2025, are entirely consistent with the consumption rates expected at this annual mileage. For the prospective buyer, a thorough physical inspection is warranted beginning with the drivetrain, given the history of CV boot failures. On a test drive, listen carefully for any clicking, knocking, or rhythmic clunking from the front suspension, particularly on full lock, as a torn or perished boot will have allowed grease to escape and contaminants to enter, accelerating wear of the joint itself. Inspect both inner and outer CV boots visually for splits, perished rubber, or displaced retaining clips, and check the surrounding suspension arms, control arm bushes, and anti-roll bar drop links for wear, as these commonly perish in the 100,000-mile region on Audi A4s and can produce clonking over speed humps or uneven roads. The 2024 advisory concerning pitted and scored front brake discs should prompt an inspection of disc thickness, lip formation, and caliper slide pin operation, with attention paid to any juddering or pulsing through the brake pedal under firm application, which would suggest disc runout beyond serviceable limits. Regarding the tyres and ancillary age-related items, the 2024 advisories for sidewall cracking and perishing on the nearside front and rear tyres are particularly relevant. Even if replacement tyres have since been fitted, the original advisories indicate that the wheels may have been subjected to kerbing or that the vehicle may be stored in conditions conducive to UV degradation. On inspection, examine the sidewalls of all four tyres for hairline cracks, bulges, or uneven wear patterns, particularly on the inner edges which can point to worn suspension bushes or alignment geometry issues. Given the eleven-year age of the vehicle, irrespective of mileage, the buyer should also verify the age and condition of the 12V battery, check for evidence of recent replacement, and confirm the servicing history for time-based items such as brake fluid, coolant, and if applicable, cambelt and automatic transmission fluid. Given that the engine MIL fault in 2022 could range from a minor sensor issue to a more substantive emissions or engine management concern, it would be prudent to request any diagnostic readout or to commission an independent scan for historic fault codes prior to purchase.
