2004 Peugeot 406 2.0L Diesel · SD04 MPF

The vehicle is currently unroadworthy following a significant mechanical failure in the April 2026 test. While the car maintained a clean record between early 2023 and 2025, the most recent inspection at 163,482 miles reveals a rapid decline in mechanical integrity. The transition from a defect-free pass to multiple critical structural and mechanical failures indicates that the vehicle has reached a point where reactive maintenance is outstripping preventative care. At 163,482 miles over 22 years, the car has averaged approximately 7,400 miles per year, which is consistent with typical low-mileage usage. However, the mileage gap between April 2025 (158,755 miles) and April 2026 (163,482 miles) shows nearly 5,000 miles driven annually, which suggests that despite the low annual average, the components are aging out and failing simultaneously due to corrosion and age-related fatigue. A buyer must exercise extreme caution regarding the structural integrity of the sills. The 2026 test identified significant corrosion on the rear suspension mounting areas and the nearside seat Analysis anchorage, both of which are safety-critical failures affecting structural strength. Furthermore, the failure of multiple wheel bearings on both the nearside front and offside rear units, combined with an excessively worn offside front suspension arm ball joint, suggests the entire suspension geometry is nearing a total overhaul. The braking system also shows a history of neglect, with the 2025 failure highlighting an ABS fault, binding calipers, and poor parking brake efficiency. The recent failure for excessive smoke emissions in April 2026 further indicates potential engine wear or turbocharger issues that require professional diagnosis. Given the severity of the structural rust and the multiple mechanical defects, the cost to return this vehicle to roadworthy standard likely exceeds its market value.
