2009 Audi A6 2.0L Diesel · LM59 DFE

The most recent MOT, dated 1 November 2023, was a pass with no recorded defects, indicating that the vehicle satisfied the current safety and emissions standards at that time. Over the six‑year MOT window the car has shown a mixed record: three consecutive passes (2018, 2019, 2020) were interrupted by a failure in late 2021 for headlamp aim and a persistent engine MIL fault, followed by a further failure in October 2023 for headlamp aim, rear‑brake imbalance and severely worn rear pads. The successful test in November 2023 suggests that the major items identified in the October failure were remedied, and the overall trend appears to be stabilising after a period of intermittent non‑compliance. At 196,494 mi the car averages roughly 11,500 mi per year, which sits comfortably within the typical usage envelope for a 2009 model. There are no large mileage gaps that would hint at prolonged storage, nor is the cumulative distance excessive for a vehicle of this age. The mileage level does, however, place the car well into the wear stage for consumables such as brake discs, pads, suspension bushings and engine oil seals, meaning that components that are not subject to strict service intervals may be approaching the end of their useful life. When inspecting the car, pay particular attention to the braking system and lighting. Verify that the rear‑brake balance is even on both sides by applying the brakes firmly at low speed and listening for any pull to one side, uneven pedal feel or vibration; a visual inspection of the rear pads should confirm that at least 3 mm of friction material remains, and the discs should be free of deep scoring or excessive rust. The headlamp units should be checked for correct vertical and horizontal aim – a simple wall test can reveal if the beams are still within the legal cone – and the lenses should be examined for clouding or moisture that could affect illumination. The engine’s MIL (malfunction indicator lamp) was flagged as inoperative in 2021; a scan with a diagnostic tool should confirm that the warning light now functions and that no stored fault codes persist, as lingering ECU issues can affect emissions compliance and fuel efficiency. Given the vehicle’s age, a thorough visual and tactile appraisal of age‑related items is essential. Inspect the tyre sidewalls for cracking, dry rot or uneven wear that may indicate suspension misalignment; the tyre tread depth should be no less than 3 mm across the tread width. Examine the suspension bushings, ball joints and shock absorbers for any signs of oil leakage, looseness or excessive play, which can manifest as clunking noises over bumps. The 12 V battery should be tested for cranking voltage and electrolyte condition, especially if the car has spent periods standing idle. Finally, confirm that the service book shows regular oil and filter changes, coolant flushes and timing‑belt or chain maintenance at the manufacturer‑specified intervals, as neglect of these calendar‑based services can lead to costly failures in the drivetrain and cooling system.
