2009 Audi A4 2.0L Diesel · GF09 TMU

A recurring pattern of tyre tread depth failures and wheel fixing issues defines the mechanical history of this vehicle, culminating in a dangerous failure on 1 December 2025. While the car achieved a pass on that same date, the preceding inspection recorded multiple dangerous defects regarding illegal tyre tread depths on both the offside front and nearside rear, alongside major defects for missing road wheel fixings on both front and rear axles. This history shows a trend of critical safety component neglect, with tyre wear advisories appearing consistently since at least 2021, interrupted by severe failures in 2022 and 2025. The vehicle has covered 162,038 miles over its 17-year lifespan, representing an average annual usage of approximately 9,532 miles. This mileage accumulation is consistent with typical long-term use for a vehicle of this age. From a mechanical standpoint, this steady rate of use suggests that components such as the suspension, braking system, and drivetrain have been subjected to regular, predictable wear rather than the stresses of high-speed motorway transit or the potential degradation associated with long periods of stationary storage. Prospective buyers should pay close attention to the suspension and steering components during a test drive. The MOT history has flagged a noisy nearside front wheel bearing and external damage to the casings of both rear shock absorbers. On the road, listen for any rhythmic humming or grinding noises from the front end that change with vehicle speed, and monitor the rear of the car for excessive bouncing or oscillations when driving over undulations, which could indicate failing shock absorber damping. Given the repeated issues with tyre wear and inflation, a thorough inspection of the current tyre condition and the alignment of the steering is essential to ensure there is no underlying geometry fault causing uneven wear. The braking system also requires scrutiny following an advisory for thin rear brake pads in 2023. During a test drive, check for any pedal judder, pulling to one side under braking, or unusual squealing sounds that might indicate worn pads or binding calipers. Additionally, because the vehicle has previously failed for missing wheel fixings, it is vital to physically verify that all wheel bolts are present, correctly seated, and that the wheel hubs show no signs of corrosion that could interfere with a secure fit. All lighting, specifically the dipped beam headlamps which were previously flagged as failing, should be tested thoroughly to ensure electrical integrity.
