2007 Audi A6 2.0L Diesel · NC07 ABK

Recurring consumable wear and minor electrical faults define the recent roadworthiness trajectory of this Audi A6, which secured a pass on 2025-12-12 after accumulating a series of escalating advisories over prior annual examinations. The latest test noted an inoperative nearside rear registration plate lamp, products affecting the clarity of both front headlamp lenses without severely compromising output, and perishing on the nearside rear inner tyre. Earlier records show a consistent pattern of repeating items, notably thinning brake pads across multiple axles flagged persistently between December 2023 and December 2024, alongside a recorded slight diesel leak from the upper engine during the 2024 test that warrants careful tracing. Having covered 160,261 miles over its nineteen-year lifespan, the vehicle averages roughly 8,435 miles annually, representing standard operational use for a large diesel executive saloon. This steady accumulation pattern means mechanical stress has been distributed relatively evenly over time rather than concentrated through periods of intensive high mileage or prolonged storage. However, high mileage on a platform of this age inherently subjects heavy components like suspension assemblies, braking systems, and powertrain ancillaries to significant cumulative fatigue, requiring a closer inspection of how these parts currently perform. On your static inspection and test drive, pay close attention to the areas highlighted in the MOT history. Verify that all four brake pads and discs have been adequately replaced given the repeated thin pad advisories from past tests, and listen closely for any squealing, scraping, or juddering under braking. Inspect the upper engine bay thoroughly with the engine running to locate the source of the previously noted slight diesel leak, checking for pooling fuel or degraded leak-off pipes around the injectors and high-pressure fuel pump. Furthermore, examine the front headlamp lenses to determine if the surface products noted by the examiner can be polished out or if the plastic degradation will eventually require professional restoration or replacement to maintain proper night-time visibility. Finally, check the condition of all tyres, paying particular attention to the perishing noted on the nearside rear inner sidewall and the historical edge wear on the nearside front, ensuring there are no dangerous sidewall cracks or bulging cords. Take the car over a varied route during the test drive to test the multi-link front and rear suspension for knocks, clunks, or excessive float over rough tarmac, as these complex suspension layouts are prone to bush and arm wear at this mileage. Confirm that all exterior lighting, including the rear registration plate lamps, operates correctly without intermittent faults.
