2013 Audi A4 3.0L Petrol · OY63 ABN

A pattern of intermittent emissions issues and recent tyre wear defines the mechanical profile of this Audi A4, following a period of clean testing between 2022 and 2024. While the vehicle passed its most recent test on 2 December 2025, the presence of an advisory for a nearside front tyre worn close to the legal limit and worn on the edge indicates a specific area of immediate consumable wear. This follows a failure in September 2024 regarding the exhaust lambda reading being outside specified limits during a fast idle test, suggesting that while the vehicle is currently compliant, the emissions system has required attention in the recent past. The recorded mileage of 91,512 miles over a thirteen-year period represents an average annual accumulation of approximately 7,039 miles. This usage level is consistent with typical long-distance or mixed-use patterns for a vehicle of this age, rather than indicating excessive heavy-duty operation or long periods of stationary storage. Mechanically, this level of mileage suggests that while major drivetrain components may not have reached extreme wear thresholds, consumables such as suspension bushes, brake discs, and exhaust components will be subject to standard age-related degradation. Prospective buyers should pay close attention to the steering and suspension geometry during a test drive, specifically addressing the advisory regarding the nearside front tyre. A tyre wearing unevenly on the edge often points to issues with wheel alignment, worn suspension bushings, or potentially a bent steering component. During the test drive, listen for any knocking or clunking sounds when navigating uneven surfaces or turning the steering wheel, and check for any pulling to one side on straight roads, which would confirm an alignment or suspension issue. Regarding the previous failure of the exhaust lambda reading, it is advisable to monitor the engine's idle stability and responsiveness. While the 2025 pass indicates the emissions are currently within legal parameters, any hesitation during acceleration or a rough, inconsistent idle could suggest the oxygen sensor or catalytic converter is beginning to underperform. Ensuring the vehicle is thoroughly warmed up during the inspection is necessary to verify that the emissions system remains stable under the fast idle conditions that caused the previous failure.
