2009 Peugeot 407 2.0L Diesel · FD09 OCX

The most recent MOT test on the 2009 Peugeot 407, conducted on 2025-01-23, resulted in a passing grade, though it included persistent advisories that suggest a pattern of recurring mechanical issues rather than a sudden deterioration. The advisories regarding near-side and offside front coil springs showing signs of corrosion are particularly notable, as they have been flagged in two consecutive MOTs, indicating a potential structural weakness in the suspension system. The front brake pad wear advisories from 2024 also highlight ongoing friction system degradation, which, if left unaddressed, could lead to reduced braking efficiency or premature failure. While the vehicle has not failed an MOT since 2018, the presence of these advisories—particularly the corrosion on coil springs—suggests that maintenance may have been reactive rather than proactive, and that the vehicle’s suspension and braking systems require closer attention moving forward. The vehicle’s recorded mileage of 117,695 miles over approximately 17 years represents an average annual usage of around 6,923 miles, which is relatively moderate for its age. Such a usage profile typically indicates that the car has been driven in a manner consistent with light to moderate daily use, though the gaps between MOT tests—particularly the two-year interval between 2019 and 2021—could imply periods of inactivity or reduced usage. This may have contributed to some wear and tear, such as the observed tyre edge wear in 2022, which could be exacerbated by underinflation or improper alignment. However, the absence of higher-mileage-related failures—such as drivetrain or exhaust system issues—suggests that the wear rate on consumables and critical components has not been disproportionately severe. Still, the combination of moderate mileage and recurring advisories on suspension and brakes warrants a thorough inspection to confirm whether these issues are isolated or indicative of underlying wear progression. For the prospective buyer, the most critical areas to inspect during a physical examination are the suspension and braking systems, given the recurring advisories. Begin with the front coil springs, checking for any signs of further corrosion, particularly around the mounting points and any visible rust streaks that could indicate water ingress. Listen for any unusual clunking or rattling noises when the vehicle is driven, especially at low speeds or when transitioning between rough and smooth surfaces, as this may signal worn suspension bushes or binding coil springs. The anti-roll bar linkages from the 2018 MOT advisory should also be scrutinised for excessive play or binding, which could lead to uneven tyre wear or handling instability. Regarding brakes, inspect the front and rear discs for signs of uneven corrosion, warping, or glazing, and check the brake pads for consistent thickness and any signs of glazing or overheating. If the pads are thin and the discs show significant wear, consider replacing them to prevent binding or reduced braking performance. Beyond the mechanical checks, the buyer should also address the potential issues related to the front brake pad warning light wires being disconnected in 2019, which could have led to a false indication or missed service reminders. This may have contributed to the thinness of the brake pads noted in subsequent MOTs, so ensuring the warning system is functioning correctly is essential. Additionally, given the vehicle’s age and the potential for standing corrosion, particularly in the suspension and undercarriage, a thorough visual inspection for rust around wheel arches, exhaust components, and the engine bay is advisable. The tyre tread depth should be checked for any signs of uneven wear beyond the legal limits, and the sidewall should be inspected for cracks or perishing, which can weaken the tyre structure over time. Finally, since the vehicle has not undergone a full service in recent years, consider verifying the service book for any missing or outdated fluid servicing, such as the brake fluid flush, which should be performed every two years or every 60,000 miles to prevent degradation of the hydraulic system. A 12V battery health check is also prudent, as older vehicles may suffer from reduced capacity or internal corrosion, which can lead to starting difficulties or electrical system failures.
