2015 Audi A4 2.0L Diesel · BJ15 VOC

The vehicle remains roadworthy but the maintenance history reveals a concerning trend of reactive rather than preventative care. The most recent test in October 2025 at 84,966 miles identified several mechanical and structural issues, including a front exhaust leak and thinning rear brake pads. While the car passed, the presence of corrosion on the front sub-frame and missing undertrays suggests that the previous owner only addressed faults when they approached an MOT failure threshold rather than performing routine mechanical inspections. At 84,966 miles over eleven years, the Audi has averaged approximately 7,700 miles per year, which is consistent with typical UK usage for a vehicle of this age. The data shows steady usage intervals, with roughly 4,600 miles covered between November 2024 and October 2025. However, the low mileage does not translate to a pristine mechanical state, as evidenced by the recurring failures of consumables and minor wear components across multiple testing cycles in 2023, 2024, and 2025. A buyer must prioritise inspecting the front sub-frame to ensure the noted corrosion in 2025 has not progressed into structural weakness. The nearside rear wheel bearing was flagged with play in late 2024 and should be checked for noise or excessive movement, as this component is prone to failure. Additionally, the consistent history of tyres wearing to the limit or unevenly across 2023, 2024, and 2025 indicates potential alignment issues or a general neglect of tyre replacement schedules. The front exhaust leak identified in the 2025 test requires close inspection to determine if it is a simple gasket failure or a corroded manifold. The rear brake pads need immediate attention as they were noted as thin in the most recent record. The missing nearside inner wheel arch cover should also be replaced to prevent road salt and moisture from damaging the bodywork, which could accelerate rust in areas already susceptible to the sub-frame corrosion.
