2003 Peugeot 406 2.0L Diesel · SA03 AHM

The vehicle is currently roadworthy, having passed its most recent MOT on 5 June 2025 at 405,884 miles. The maintenance trend appears stable in terms of reported defects, as the record shows a clean pass with no advisories. However, a pattern of multiple failures immediately preceding the passes in both 2024 and 2025 suggests the vehicle often requires remedial work just before it can meet minimum legal standards. The mileage is exceptionally high for a 2003 model, averaging over 17,000 miles per year. Between the May 2024 test at 400,383 miles and the June 2025 test at 405,884 miles, the car covered 5,501 miles. This consistent usage indicates the vehicle has been used as a high-mileage workhorse rather than sitting idle, which generally helps prevent seizure in braking components but accelerates wear on the drivetrain. A buyer must scrutinize the chassis and suspension for fatigue. While the MOT records are curiously devoid of specific defect descriptions despite multiple failures, a car with over 400,000 miles typically suffers from worn suspension bushes, sagging coil springs, and significant corrosion on structural mounting points. The lack of detailed advisories on a vehicle of this age and mileage is unusual and warrants a thorough physical inspection of the underbody. Priority should be given to checking the condition of the timing belt and water pump, as these are critical failure points on this engine. Inspect the brake discs for thinning and check for any play in the steering rack. Given the high mileage, the internal condition of the engine and the efficiency of the exhaust emissions system should be verified to ensure the vehicle remains reliable under load.
