2014 Audi A4 2.0L Diesel · C27 ONG

Recurring steering and tyre-related failures define the mechanical profile of this Audi A4, with the most recent test on 29 October 2025 showing a pass following a dangerous failure the previous day. The vehicle has a history of structural and component wear, specifically regarding the track rod ends and tyre integrity, which necessitated a dangerous classification due to structural separation in both offside and nearside rear tyres. While the most recent result shows a pass, the persistent advisory regarding play in the offside front track rod end indicates an ongoing issue with steering linkage components that has appeared in multiple recent tests. The recorded mileage of 78,375 miles over approximately twelve years equates to an annual average of roughly 6,531 miles. This represents a relatively low rate of accumulation for a vehicle of this age, which can sometimes correlate with longer periods of inactivity or shorter, localized journeys. Mechanically, this usage pattern means that while drivetrain mileage may be lower than average, components such as suspension bushes, seals, and rubber elements are more susceptible to age-related degradation and perishing rather than purely wear-based exhaustion. Prospective buyers should pay close attention to the steering and suspension geometry during a test drive. The repeated advisories for the offside front track rod end suggest a need for close inspection of the steering rack and associated linkages. Listen for clicking or clunking sounds when turning the steering wheel at low speeds or when maneuvering, and feel for any wandering or lack of precision in the steering response. Additionally, the 2024 advisory regarding the offside front suspension lower arm rear bush indicates previous wear in the suspension mounting points; check for any shuddering through the chassis or uneven tyre wear that could stem from worn bushes. Structural integrity should also be a primary focus, particularly regarding the rear subframe which was recorded as corroded in 2023. While the subframe was not a failure point in the most recent test, corrosion is progressive. A physical inspection of the underside is necessary to assess the extent of the oxidation on the subframe and exhaust mountings. On the road, be alert for any unusual vibrations or heavy thudding from the rear of the vehicle when travelling over uneven surfaces, which could indicate that the subframe or exhaust mounting issues have progressed beyond the previously recorded advisory levels.
