2012 Audi A4 2.0L Diesel · DF12 XDA

The latest MOT test passed on 6 October 2025 with no recorded defects, following a dangerous failure for excessive nearside rear wheel bearing play. While the most recent result is positive, the overall maintenance trend appears reactive rather than proactive. The history shows repeated failures involving the engine malfunction indicator lamp and mechanical issues such as binding brakes and steering component play. This suggests that while the vehicle is currently roadworthy, it has a history of component degradation that is often only addressed once it reaches a critical or failing threshold. With 107,036 miles recorded over 14 years, the vehicle has averaged approximately 7,645 miles per year. This represents relatively low annual usage for an Audi A4, which typically implies less mechanical wear on the engine and drivetrain compared to high-mileage examples. However, this usage pattern carries the risk of age-related degradation. Components made of rubber, such as suspension bushes and tyre sidewalls, can perish from UV exposure and lack of movement, and fluids may undergo chemical degradation even if mileage remains low. During your inspection and test drive, you must scrutinise the suspension and steering systems. The previous advisories for track rod end play and uneven inner tyre wear are indicative of potential issues with wheel alignment or worn control arm bushes. Listen for any knocking, clunking, or creaking sounds when turning the steering wheel or driving over bumps, and check for any steering wheel vibration at speed. Given the recent dangerous failure of the nearside rear wheel bearing, pay close attention to any humming, droning, or grinding noises emanating from the rear of the vehicle, as these are classic symptoms of bearing failure. You should also verify the integrity of the electronic monitoring systems. The repeated failures regarding the engine malfunction indicator lamp mean you must confirm that all dashboard warning lights illuminate correctly when the ignition is first turned to the on position. Inspect the tyres thoroughly for sidewall cracking or perishing, as noted in previous advisories, and check the brake discs for excessive corrosion or uneven wear that could indicate binding calipers. Finally, verify the service book to ensure that maintenance has been performed on a calendar basis for fluids like brake fluid and coolant, rather than relying solely on mileage intervals, to mitigate the effects of age and standing.
