2010 Peugeot 407 1.6L Diesel · LR10 DXC

The most recent MOT inspection on 7 March 2026 resulted in a pass, though the vehicle continues to carry recurring advisories regarding an oil leak and headlamp lens degradation. While the vehicle has successfully cleared previous failures related to steering components, seat belts, and wiper mechanisms, the maintenance trend suggests a pattern of reactive rather than preventative care. The persistence of the oil leak advisory across multiple consecutive tests indicates a long-standing issue that, while currently deemed non-excessive, requires close monitoring to ensure it does not escalate into a significant loss of pressure or a fire hazard. With a recorded mileage of 69,507 over approximately 16 years, this Peugeot 407 has been driven an average of only 4,344 miles per year. This is significantly below the UK national average and classifies the vehicle as low mileage for its age. While low mileage generally implies less wear on the engine internals, gearbox, and drivetrain, it also presents specific risks associated with infrequent use. Vehicles that spend long periods stationary are prone to accelerated degradation of rubber components, fluid acidification, and moisture accumulation within the exhaust and braking systems. The recurring advisory for an oil leak is the most significant mechanical concern. During your test drive, you should inspect the engine bay and the ground beneath the vehicle for fresh fluid deposits. Listen for any rhythmic tapping or increased engine noise which could indicate oil starvation, and check the oil level frequently. The advisory regarding the headlamp lenses suggests oxidation or UV damage to the plastic covers. While currently passing, this will eventually lead to reduced light output and poor beam patterns, so check that the illumination is bright and even during evening testing. You should also verify that the steering rack gaiter, which was a major failure in 2025, has been fully replaced and is not leaking fluid, as a compromised gaiter can lead to premature steering rack failure. Given the low annual mileage, you must perform a thorough physical inspection of all age-related consumables. Examine the tyre sidewalls for signs of perishing, cracking, or dry rot, as tyres can become structurally unsafe due to age even if the tread depth remains high. Check the brake discs for heavy surface corrosion or pitting, which can occur when the vehicle is not driven frequently enough to clear the oxidation. Additionally, inspect the various suspension bushes and control arms for perished rubber, as the previous history of worn bushes suggests these components are reaching the end of their service life. Finally, confirm that the service history includes regular oil and filter changes based on time intervals rather than just mileage, to mitigate the risks of fluid degradation from long periods of standing.
