2013 Audi A3 1.4L Petrol · HW63 ECN

The vehicle is currently roadworthy but the recent history reveals a worsening trend regarding engine emissions and mechanical component degradation. While it passed the most recent test on 21 May 2026 at 80,014 miles, it failed just one day prior at 79,997 miles. The recurrence of high carbon monoxide and lambda sensor failures in both 2025 and 2026 suggests a persistent issue with the fuel management system or exhaust catalyst that has not been comprehensively rectified. The mileage pattern remains consistent with a 13-year-old vehicle, averaging approximately 6,155 miles per year. The car covered 4,478 miles between the May 2024 and May 2025 tests, and another 5,148 miles between May 2025 and May 2026. This relatively low annual distance typically reduces wear on the drivetrain and engine, but the long intervals between tests can sometimes lead to the degradation of rubber-based components, which is evidenced here in the recent failure of the brake hose boot. A buyer must prioritize a professional inspection of the exhaust system to address the recurring carbon monoxide and lambda sensor readings. The repeated failures indicate the engine is running poorly or has a failing catalytic converter. Additionally, the tester flagged a deteriorating offside rear brake hose boot and a damaged nearside front tyre sidewall; these require immediate attention to prevent fluid leaks or a blowout. The exterior body damage noted across multiple years should also be inspected to ensure it has not hidden structural corrosion or compromised mounting points.
