2010 Audi A5 2.0L Petrol · WM59 FPP

The most recent MOT test on the 2010 Audi A5 recorded a passing result, but the vehicle’s maintenance history reveals a pattern of recurring advisories and one critical failure that should not be overlooked. While the vehicle has passed subsequent tests, the consistent presence of oil leaks and oil-misted front shock absorbers suggests underlying wear in the suspension system, particularly in the lower control arms and potentially the strut mounts. The rear subframe corrosion advisory from the latest MOT indicates structural degradation that, if left unaddressed, could compromise the vehicle’s long-term structural integrity and lead to costly repairs such as subframe replacement or even suspension failure. The tyre failure from 2024—where multiple tyres exhibited exposed cords and insufficient tread depth—demonstrates a failure to maintain proper tyre condition, which is a significant risk for road safety and hydroplaning during wet conditions. The vehicle’s mileage of 188,043 miles over approximately 16 years represents a moderate annual usage rate of around 11,753 miles per annum, which is typical for a car of this age and class. However, the significant gap between the 2024 failure and the 2026 MOT—nearly two years—could imply periods of prolonged inactivity, which often exacerbates issues such as brake pad wear, fluid degradation, and corrosion from standing. While lower mileage might suggest less wear on consumables like oil and brake pads, the combination of high mileage and standing time means the vehicle has experienced both mechanical stress and environmental exposure, accelerating wear on critical components like seals, bushings, and suspension elements. For a prospective buyer, the most pressing concerns stem from the recurring oil-related advisories and the structural corrosion in the rear subframe. On inspection, check for persistent oil leaks under the vehicle, particularly around the front suspension mounts and oil pans, and listen for unusual clunking or rattling noises from the suspension during cornering or over bumps, which may indicate failing strut mounts or bushings. The exposed tyre cords and low tread depth from the 2024 failure necessitate immediate replacement of all tyres to meet legal requirements and ensure safe traction. Additionally, the thin brake pads from the 2023 MOT should be replaced as soon as possible to prevent brake disc warping or overheating, which could lead to binding calipers or reduced braking performance. Given the vehicle’s age and the history of standing, inspect the brake discs for corrosion or binding, and verify that the brake fluid has not degraded over time—this is critical for maintaining effective braking under all conditions. Beyond the mechanical concerns, a thorough physical inspection should include checking the tyre sidewalls for signs of perishing or cracking, which can indicate long-term exposure to UV radiation and reduce tyre lifespan. Verify the 12V battery health, as prolonged standing can drain batteries, and test the starter motor and alternator for proper function. Inspect the exhaust system for leaks or excessive rust, as emissions-related corrosion can weaken the structure and lead to leaks or catalytic converter failure. Finally, review the service history for the timing belt replacement, which for this model should have been conducted around 100,000–120,000 miles; if this has not been done, it poses a significant risk of catastrophic engine failure. Ensure that all fluids—oil, coolant, brake fluid, and transmission fluid—are topped up and free from contaminants, as standing vehicles can lead to fluid degradation over time.
