2009 Audi A3 1.9L Diesel · FD09 OSF

The most recent MOT test on 13 October 2025 resulted in a pass, but the inclusion of an advisory regarding light oil misting on the nearside rear shock absorber suggests a shift toward wear-related maintenance. Looking at the broader history, the maintenance trend appears reactive rather than preventative. The vehicle has experienced significant failures in the past, including dangerous defects related to tyre tread depth and brake pad thickness, as well as major failures concerning a fractured coil spring and a split CV boot. While these critical safety issues were rectified to achieve subsequent passes, the current advisory indicates that suspension components are beginning to show signs of age-related degradation. With 160,504 miles recorded over approximately 17 years, the vehicle has averaged roughly 9,441 miles per year. This level of usage is considered typical for a vehicle of this age and suggests a consistent driving pattern rather than long periods of inactivity. While the steady mileage helps mitigate the risk of seized brakes or fuel system degradation, the high cumulative mileage means that major mechanical components such as the timing belt, water pump, clutch, and dual-mass flywheel will likely be approaching or have exceeded their typical service life. You must verify the service history to ensure these high-cost items have been addressed. During your inspection and test drive, pay close attention to the rear suspension. The advisory for oil misting on the shock absorber means you should listen for any rhythmic knocking or excessive bouncing when traversing uneven road surfaces, which would indicate the damper is failing. Furthermore, because the 2025 MOT noted that under-trays were obscuring certain components, you should ask for a visual inspection of the engine bay and lower chassis. Check specifically for any signs of active oil or coolant leaks around the sump and steering rack that may have been hidden from the tester. Finally, given the previous history of fractured springs and split CV boots, inspect the entire suspension assembly for perished rubber bushings and any signs of grease leakage from the drive shafts. Ensure that the CV boots are intact and that no clicking sounds occur when turning the steering wheel under load. You should also examine the brake discs for significant corrosion or uneven wear and check the tyres for any sidewall cracking or perishing, which can occur on older vehicles even if the tread depth remains sufficient. Confirm that the service records show regular oil changes and that the brake fluid has been replaced according to the manufacturer's recommended intervals.
