2000 Peugeot 406 2.0L Diesel · X941 BBL

Structural integrity and suspension component wear represent the primary mechanical concerns for this Peugeot 406, given the recurring issues with corrosion and mounting points. The vehicle's history shows a pattern of escalating concerns regarding the nearside rear suspension component mounting, which progressed from an excessive corrosion failure in May 2019 to a continued advisory for corrosion in the same area in September 2021. This trend, alongside advisories for engine mount damage and worn suspension bushes, indicates that while the vehicle passed its most recent test on 29 September 2021, the underlying issues with chassis corrosion and rubber component degradation remain present. The recorded mileage of 117,427 miles over approximately 26 years averages to roughly 4,516 miles per year, which is low for a vehicle of this age. This low annual accumulation suggests the car has spent significant periods stationary or has been used for very short journeys. Mechanically, such a usage pattern can lead to the degradation of rubber elements like suspension bushes and engine mountings, as well as potential issues with braking components, which is consistent with the recorded history of imbalanced brakes and worn linkages. A prospective buyer should pay close attention to the condition of the sills and suspension mounting points during a physical inspection. The history of corrosion on the nearside rear mounting area and the advisory regarding the offside rear brake pipe being corroded and covered in grease necessitates a thorough check of the underside for structural rust. On a test drive, listen for knocks or clunks when traversing uneven surfaces, which could indicate the reported wear in the offside front lower suspension arm bush or the Macpherson strut upper support bearings. Any pulling to one side or uneven steering response may also point to the previously noted suspension irregularities. Braking performance and stability should also be scrutinised. Given the 2017 failure involving imbalanced brakes across the axle and a lack of effort on the offside rear, the driver should test for any pedal judder, pulling under braking, or uneven deceleration. The presence of an advisory for a damaged lower engine mounting suggests that the vehicle may exhibit increased vibrations through the steering wheel or cabin, particularly during idling or when accelerating from a standstill. Ensuring the supplementary restraint system is fully functional is also vital, following the previous failure of the SRS warning lamp.
