2012 Peugeot 107 1.0L Petrol · WN12 ODT

Persistent corrosion of the rear brake pipes represents the primary mechanical concern for this vehicle, as this specific defect has been flagged as an advisory in every annual test from 2023 through to the most recent pass on 13 February 2026. While the vehicle successfully cleared its latest MOT following a brief failure for lighting and washer system defects, the recurring mention of brake pipe degradation suggests a structural issue that has not been rectified despite repeated warnings. The overall trend indicates a pattern of deferred maintenance regarding critical safety components, with the braking system showing consistent signs of age-related deterioration that now requires immediate professional assessment. Accumulating 82,283 miles over fourteen years results in an average annual usage of approximately 5,877 miles, a figure that is relatively low for a vehicle of this age. While this limited mileage might suggest reduced wear on high-friction drivetrain components, it often correlates with short-journey cycles that prevent the engine and exhaust system from reaching optimal operating temperatures. Prospective buyers should be aware that such usage patterns can lead to premature internal corrosion within the exhaust system and may contribute to the accelerated surface degradation observed on the brake lines and suspension components due to prolonged exposure to road salt and moisture without the benefit of consistent high-speed drying. During a test drive, the condition of the front anti-roll bar linkages and brake discs must be prioritised, as both were flagged as worn or pitted in recent inspections. Listen carefully for any knocking or metallic clunking noises originating from the front suspension when traversing speed bumps or uneven road surfaces, which would indicate excessive play in the linkage pins or bushes. Additionally, perform several controlled stops to check for pedal judder or a grinding sensation, as the reported pitting on the front discs can compromise braking efficiency and lead to uneven pad wear. Any steering pull or vibration under braking should be treated as a sign that these components require replacement rather than simple adjustment. The integrity of the rear brake pipes must be physically inspected before purchase, as the MOT examiner noted they were covered in grease or other material, which can sometimes be used to mask the severity of corrosion. Ensure that the pipes are not pitted or flaking, as any structural weakness here poses a significant risk of fluid loss under heavy braking pressure. Furthermore, verify that all lighting systems, including the stop lamps and registration plate lights, operate correctly, as the vehicle has demonstrated a recurring history of minor electrical failures. A thorough check of the windscreen washer system is also advised, given its recent failure, to ensure the pump and nozzles are fully functional and clear of debris.
