2016 DS DS3 1.6L Diesel · BP65 AVB

Recurring corrosion and structural failure within the rear suspension system define the mechanical history of this vehicle. While the test on 3 October 2025 resulted in a pass, it highlighted a continuing trend of deterioration with both nearside and offside rear coil springs now recorded as corroded. This follows a major failure in 2022 for a fractured nearside rear spring, suggesting a persistent vulnerability in the rear chassis components. The latest record also introduces an oil leak, which, although noted as not excessive, indicates a new point of mechanical concern. The recorded mileage of 53,862 miles is low for a vehicle of this age, averaging approximately 5,386 miles per year. This usage pattern is reflected in the MOT history, specifically the 2022 and 2023 records where tyres were flagged for perishing, cracking, and structural failure. Such patterns often emerge when vehicles spend extended periods stationary, leading to the degradation of rubber components regardless of the low tread wear. A test drive should focus heavily on the suspension and drivetrain. Listen for knocks or clunks from the rear of the vehicle when traversing uneven surfaces, which would indicate further deterioration of the corroded coil springs. Pay close attention to the steering and front end during tight, low-speed manoeuvres; any clicking or popping sounds from the offside front could suggest that the previously failed constant velocity boot has allowed contaminants into the joint. Additionally, check for any exhaust rattles or vibrations, given the history of broken centre and rear exhaust brackets. Brake performance and engine sealing require objective verification. During braking, feel for any pedal judder or pulsing, which would correlate with the 2022 advisories regarding pitted and scored brake discs. The presence of the oil leak noted in 2025 should be investigated by inspecting the engine bay for fresh residue and checking the ground beneath the vehicle for drips. Finally, examine the current state of all four tyres for any signs of sidewall cracking or perishing, as this has been a recurring defect in the vehicle's testing history.
