2012 Peugeot 107 1.0L Petrol · YR62 AAN

A recurring theme of brake-related defects and rear underbody corrosion runs through the MOT history of this 2012 Peugeot 107, painting a picture of a vehicle where the braking system and rear structure demand close scrutiny. The most recent test on 29 September 2025 was a pass, but it carried three advisories: a corroded rear brake pipe coated in grease or similar material, a minor exhaust gas leak at the rear, and light corrosion to the rear sills and subframes. This follows a fail on 26 September 2024 where both front service brakes showed excessive fluctuation and the offside headlamp failed on both dipped and main beam, with the wiper defect then appearing as a minor on the subsequent pass a day later. The September 2023 test outcome is particularly telling, recording a fail for excessively fluctuating front brake performance, a corroded offside rear brake pipe, and lagging nearside front brake operation, alongside another advisory for the nearside rear brake pipe corrosion. The brake pipe corrosion advisory has therefore appeared in two consecutive annual tests, and the rear underbody corrosion advisory is now present at the most recent inspection, suggesting a progressive rather than resolved mechanical issue. Against the vehicle's fourteen-year age, the recorded 73,577 miles equates to roughly 5,256 miles per year, which is low for the model and indicative of either light general use or significant periods of standing. Five tests appear in the record over consecutive years with no multi-year gaps that would suggest prolonged off-road status, so the mileage appears to have been accumulated gradually. Light annual mileage reduces wear on major drivetrain components such as the engine, clutch and gearbox internals, but it can also accelerate corrosion in areas protected primarily by regular use, as surface oils and movement help displace moisture from underbody seams, brake pipes and subframe mounting points. The repeated brake pipe advisories, particularly given that the nearside rear pipe was flagged in 2023 and the rear pipes again in 2025, are consistent with a low-mileage car where corrosion has had time to develop on components that have seen less thermal cycling and mechanical disturbance than a higher-mileage equivalent. For a prospective buyer, the priority on inspection is the braking system and the rear underbody structure. On a test drive, listen for any knocking or clonking from the front brakes when pulling away at low speed, as the previous fluctuating brake readings can indicate worn caliper slides, distorted discs, or sticking pistons. Apply the brakes firmly at around 30 mph and feel for judder through the pedal or steering wheel, which would suggest disc runout or uneven pad transfer, and note any pull to one side which could indicate a seized caliper or hydraulic imbalance. On the rear, any sponginess in the pedal or a need to pump the pedal to maintain pressure could indicate air ingress through the corroded pipe unions, and the handbrake should be examined for adequate holding force on a slope. The vehicle should be raised on a ramp if possible to inspect the rear brake pipes along their full length for rust scaling, pitting or active leakage, particularly at the unions near the axle and under the rear sill area where the advisories have been concentrated. The rear sill and subframe corrosion advisory recorded at the latest test, while currently classed as light, warrants a hands-on inspection with a screwdriver or magnet to gauge the depth of any surface corrosion, particularly around jacking points, trailing arm mounts and the spare wheel well. An exhaust gas leak at the rear is typically joint-related rather than pipe failure at this stage, but on the road a distinct ticking under light load or a louder exhaust note than expected would confirm whether it has worsened since the test. The headlamp failures from 2024 should not recur on a vehicle of this age unless the bulbs or wiring have been disturbed, but it is worth confirming that both dipped and main beam function correctly and that the lens units are not heavily oxidised, which on a 107 can allow moisture ingress. Finally, given the brake pipe advisories appearing in consecutive years, any negotiation should account for the realistic cost of new rear brake pipe sections and a thorough brake overhaul including caliper inspection, as these are the items most likely to require attention to keep the vehicle roadworthy beyond the next test.
