2009 Audi A6 2.0L Diesel · CP59 FPD

Recurring issues with braking components and tyre condition define the mechanical profile of this Audi A6, with the most recent test on 31 January 2024 showing advisories for both nearside and offside front brake pads wearing thin. This follows a significant failure on 30 January 2024, where the vehicle was flagged with dangerous defects regarding rear brake pad thickness and insufficient tyre tread depth on the offside rear. The history shows a pattern of consumables reaching the end of their service life abruptly, alongside repeated advisories for tyre degradation, including sidewall cracking and perishing on the nearside rear recorded in both 2022 and 2023. The vehicle has covered 177,969 miles over its approximately 17-year lifespan, representing an average annual accumulation of roughly 10,469 miles. This usage pattern is consistent with typical long-term road use for a vehicle of this age. Mechanically, this level of mileage suggests that while the vehicle has not been subjected to extreme high-speed motorway transit, the cumulative wear on suspension bushings, steering components, and drivetrain elements will be significant. The consistent annual mileage indicates a steady progression of component fatigue rather than the potential issues associated with long periods of stationary use. Prospective buyers should pay close attention to the suspension and steering geometry during a test drive, given the recorded failures involving the nearside front lower anti-roll bar linkage and the offside front anti-roll bar ball joint. Listen for rhythmic knocking or clunking sounds when traversing uneven surfaces or speed bumps, which can indicate excessive play in these linkages or worn bushes. Additionally, the history of engine Malfunction Indicator Lamp (MIL) failures in 2021 and 2022 warrants a thorough check of the dashboard for any active warning lights and a verification that the diagnostic system is communicating correctly with the engine management unit. Braking performance and tyre integrity require immediate scrutiny. Given the recent advisories for thinning front pads and previous dangerous failures for rear pads, a test drive should include several controlled braking applications to check for pedal judder, pulling to one side, or any unusual squealing. The vehicle should also be inspected for tyre sidewall integrity; look specifically for the cracking or perishing noted in previous years, particularly on the inner walls of the rear tyres. Ensure that the current tread depth across all four tyres is well above the legal 1.6mm limit to avoid the immediate safety risks identified in the 2024 failure.
