2009 Audi A4 1.9L Diesel · LL09 OPJ

The most recent MOT test passed on 10 October 2025, although the report included advisories for both front and rear brake pads being worn thin. This indicates a recent shift in the vehicle's maintenance trend; while the 2022 and 2023 inspections showed no defects, the 2025 records suggest the vehicle is entering a phase where consumable components require replacement. As the most recent test was recorded nearly a year ago, these brake pads are likely significantly closer to the legal limit now, meaning immediate maintenance will almost certainly be required to ensure continued roadworthiness. With a recorded mileage of 102,540 miles over approximately 17 years, the vehicle has averaged roughly 6,032 miles per year. This represents relatively low annual usage, which can be beneficial for the longevity of the engine and drivetrain, but it also carries the risk of component degradation due to infrequent use. Low-mileage vehicles are often subject to more stop-start driving, which can increase wear on the starter motor, battery, and braking components, and may lead to moisture accumulation in the exhaust and engine oil if the vehicle is not driven long enough to reach optimal operating temperatures regularly. The advisories regarding thinning brake pads and previous uneven tyre wear are the primary areas for inspection. During a test drive, listen for high-pitched squealing or grinding noises, which indicate the wear indicators or metal backing plates are contacting the discs. You should also check for any brake pedal sponginess or a shuddering sensation through the pedal when braking, which could signal that the discs are warped or that the calipers are binding. Furthermore, the previous advisory regarding an offside front tyre being worn on the edge suggests a potential alignment issue or worn suspension bushes. Inspect the current tyres for uneven tread wear, which could indicate that the geometry of the front suspension requires adjustment or that components like control arms or shock absorbers are failing. Given the vehicle's age and usage profile, a thorough physical inspection is essential. Check the tyres for signs of perishing or sidewall cracking, which can occur even if tread depth is sufficient if the vehicle has been parked for long periods. Inspect the vehicle's underside for excessive corrosion on the exhaust system and chassis, and look for any evidence of fluid leaks from the engine or transmission. It is also vital to verify that the service history includes regular oil changes based on time intervals rather than just mileage, as oil degrades chemically over time regardless of distance driven. Finally, ensure the 12V battery is holding a strong charge and check that the brake discs are free from excessive surface corrosion or binding, which can occur when a vehicle is driven infrequently.
