2015 Audi A5 2.0L Diesel · EL14 NER

A persistent vulnerability to structural tyre damage stands out as the defining mechanical concern in this Audi A5 history, underscored by consecutive dangerous failures for sidewall bulges on the rear tyres in September 2024 and November 2025. Beyond these severe structural tyre defects, the record reveals recurrent initial rejections, including a headlamp levelling device failure in 2023 and ineffective windscreen wipers during the November 2025 testing cycle before a subsequent pass was achieved on November 7, 2025. While clean passes were logged in 2021, 2022, 2023, and 2024, the recurring presence of major and dangerous items on initial presentations points to a pattern of component fatigue that requires careful scrutiny. Accumulating 54,649 miles over its roughly eleven-year lifespan translates to an average of around 4,968 miles per year, placing this vehicle well into a low-usage bracket. This modest annual mileage indicates lighter overall transit, but lower utilization can occasionally mask age-related degradation on rubber components, suspension linkages, and exhaust systems that may not be exposed to high-frequency road wear yet still suffer from environmental aging. Testing consistency remains solid with annual checks performed regularly, though the restricted mileage means potential buyers must verify that the vehicle has been operated frequently enough to prevent seizing of moving parts and stagnation of fluids. On the test drive, the prospective buyer must pay rigorous attention to the steering and suspension geometry, specifically listening for any knocking, creaking, or structural thuds from the rear axle that could relate to the history of tyre sidewall failures or stress on the underlying wheel assemblies. Inspecting the inner and outer sidewalls of all four tyres for matching premium brands, adequate tread depth, and uniform wear patterns is essential given the repeated structural tyre faults noted in past MOTs. Furthermore, a thorough operational check of the adaptive or manual headlamp levelling system is vital to ensure the self-levelling sensors and motors function correctly, avoiding the specific electrical fault that caused a test failure in 2023. Finally, the exhaust system warrants physical inspection from underneath to evaluate the condition of the central exhaust clamp previously flagged as corroded in 2021, ensuring no minor degradation has escalated into blowing joints or insecure hanging brackets. The electrical systems, particularly the automatic wiper sweep and headlamp mechanisms, should be tested repeatedly during a stationary run to confirm that past component faults have been fully rectified rather than temporarily patched. Verifying these specific points during an independent pre-purchase inspection will provide the necessary clarity on the physical longevity of these vulnerable areas.
