2005 Audi A4 2.5L Diesel · OV05 ACO

The vehicle presents a questionable roadworthiness profile due to a maintenance history defined by recurring failures and deferred mechanical repairs. While the most recent test in January 2023 at 190,967 miles passed, it carried advisories for deteriorated front suspension ball joint dust covers and worn upper arm bushes. Given that it has been over three years since the last recorded test, the vehicle is currently operating without a valid MOT certificate. The trend suggests a reactive maintenance approach where components are only addressed after they fail an inspection rather than through proactive preventative care. At 190,967 miles over 21 years, the Audi A4 has averaged approximately 9,100 miles per year, which is consistent with a vehicle of this age. However, the data shows a period of significant neglect between October 2020 and October 2021, where the car covered 4,058 miles but suffered multiple consecutive failures. The October 2020 failure is particularly concerning, flagging a loose road wheel fixing and a tyre below the legal tread depth limit alongside mechanical faults, indicating that basic safety-critical checks were completely ignored during that interval. A buyer must conduct a thorough physical inspection of the front suspension geometry. The record shows a persistent history of worn upper arm bushes and ball joint dust covers dating back to 2015, indicating these components are a known weak point on this specific vehicle. The ABS warning lamp fault recorded in October 2021 at 187,750 miles requires a diagnostic check to ensure the sensor or module was actually rectified. Additionally, the history of excessive metered smoke noted in 2015 and 2016 suggests potential turbocharger or engine health issues that should be monitored for blue or heavy black smoke during a test drive.
