2012 Audi A4 2.0L Diesel · FM12 AAK

The most recent MOT inspection on 20 August 2026 resulted in a pass, but the vehicle's maintenance profile shows a concerning downward trend in mechanical condition. While the vehicle passed in 2023 and 2024 without any recorded defects, the 2025 and 2026 tests have introduced an increasing number of advisories and minor failures. The progression from a clean record to multiple simultaneous issues regarding drivetrain, suspension, and braking systems suggests that the vehicle is entering a phase of significant wear-and-tear maintenance. The recurrence of drive shaft CV boot deterioration and the emergence of new oil leaks and suspension component wear indicate that the vehicle's ability to maintain roadworthiness without imminent investment is diminishing. With 168,925 miles recorded over approximately 14 years, this Audi A4 has averaged roughly 12,000 miles per year. This is a standard to slightly high level of usage for a diesel or petrol saloon of this age, suggesting it has been used regularly for commuting or long-distance travel rather than sitting idle. While consistent usage can often prevent issues like brake binding or battery discharge, the high cumulative mileage means that major mechanical components such as the turbocharger, clutch or dual-mass flywheel, and timing components are likely nearing the end of their service life. The high mileage correlates directly with the recent appearance of suspension bush wear and shock absorber misting, which are typical consequences of long-term structural fatigue. A prospective buyer must exercise caution regarding the documented oil leak and the misting of the front shock absorbers. During a test drive, you should look for any signs of engine oil pooling on the underside of the sump or dripping from the engine casing, and listen for any rhythmic knocking or heavy bouncing when driving over uneven surfaces, which would indicate the shock absorbers have lost their damping effectiveness. The advisory regarding the offside front CV boot is critical; if this boot fails completely, grease will escape and grit will enter the joint, leading to a loud clicking sound when turning the steering wheel at low speeds. Furthermore, the worn tyre on the edge and the thinning rear brake pads suggest that a significant expenditure on consumables is imminent. The suspension advisories regarding the nearside and offside front arm bushes require close attention. On the road, these worn components often manifest as steering wander, imprecise handling, or a dull thudding sound when braking or accelerating. You should also inspect the brake discs for deep scoring or heavy corrosion, as the thin pads will soon require replacement alongside new discs to ensure effective stopping power. Given the high mileage and the recent influx of advisories, it is highly recommended that you verify the service history to ensure that oil changes and fluid replacements have been performed at regular intervals, as the current oil leak could lead to long-term engine lubrication issues if left unaddressed.
