2004 Peugeot 407 2.0L Diesel · KB04 WRT

The latest MOT record from June 2024 indicates a pass, though this followed a failure regarding a major defect involving the electronic stability control warning lamp. This suggests a recent electrical or sensor-related fault that required attention to ensure the vehicle's safety systems were functional. While the overall maintenance trend appears relatively stable, the intermittent appearance of tyre-related issues and electronic warnings suggests that while the vehicle may be mechanically sound, certain peripheral systems and consumables require closer scrutiny. The recorded mileage of 72,863 miles over a 22-year period represents an exceptionally low annual usage rate of approximately 3,312 miles. While this low mileage typically implies reduced wear on the engine, transmission, and drivetrain, it carries the inherent risks associated with vehicles that spend long periods stationary. Low usage can lead to the degradation of rubber components, the drying out of engine seals, and the accumulation of moisture within braking and cooling systems, which can result in corrosion or component seizure over time. A primary concern for a prospective buyer is the history of tyre-related defects, including a dangerous structural bulge in 2020 and advisories for perishing rubber in 2023. You must conduct a thorough visual inspection of the tyre sidewalls for any signs of cracking, perishing, or bulging, regardless of the remaining tread depth. During the test drive, pay close attention to any vibrations through the steering wheel or uneven tyre wear, which could indicate tracking issues or internal tyre failure. Furthermore, ensure that the electronic stability control warning lamp does not reappear during operation, as this could indicate an intermittent sensor or electrical fault. Given the vehicle's profile of infrequent use, you should also inspect the underside for signs of standing corrosion, particularly on the exhaust system and brake discs. Check for binding calipers or a heavy pedal feel, which may indicate moisture ingress in the brake fluid. It is essential to verify the service history to ensure that maintenance has been conducted on a calendar basis rather than solely on mileage, specifically regarding oil changes, coolant flushes, and brake fluid replacements. Finally, inspect all suspension bushes and engine hoses for signs of hardening or cracking, as these components are highly susceptible to age-related degradation when not regularly exercised.
