2009 Peugeot 107 1.0L Petrol · WM09 HSF

The most recent MOT on 1 April 2026 resulted in a failure, the principal reasons being a non‑functioning nearside registration plate lamp and an inoperative engine malfunction‑indicator lamp (MIL). While the test also recorded several advisories – low engine oil level, corrosion of the rear silencer and mid‑pipe, and corrosion on the rear brake hose and pipe – the presence of the two safety‑critical failures marks a deterioration from the previous years, which were all passes with only advisory items. Over the last three years the pattern has shifted from clean passes (2019‑2021) to a growing list of corrosion‑related advisories and now a failed safety check, suggesting the vehicle’s condition is currently worsening rather than stabilising. At 96 395 mi the car has covered an average of roughly 5 700 mi per annum over its 17‑year life, a mileage well below the typical usage for a small hatchback of this age. Such low annual mileage often indicates periods of infrequent use or prolonged storage, which can accelerate age‑related degradation of rubber components, corrosion of steelwork and battery deterioration, even though the mechanical wear from distance is modest. The relatively low wear on the drivetrain and chassis is a positive sign, but the limited mileage does not offset the evident corrosion and fluid‑level concerns highlighted in the recent MOT. A prospective buyer should give particular attention to the exhaust system and braking hydraulics. Inspect the rear silencer, mid‑pipe and any adjoining brackets for rust perforation, loose mounts or holes that could allow exhaust gases to escape near the cabin; a hissing or ticking sound on acceleration, especially at low revs, would confirm a leak. Examine the rear brake hose and pipe for any signs of external cracking, swelling or fluid seepage, and consider a full hydraulic bleed and replacement of the corroded hose to ensure reliable braking. The front brake discs have been flagged as worn and pitted on several occasions and the pads were noted as thin in 2020; measure disc thickness and pad remaining material, and be prepared for disc resurfacing or replacement if the scoring is beyond the minimum safe limit. Verify that the nearside registration plate lamp operates correctly and that the MIL does not illuminate when the engine is running – a persistent MIL could indicate an underlying engine management fault that may affect emissions compliance and fuel economy. Beyond the recorded defects, age‑related checks are essential. Confirm the tyre sidewalls are free of cracking or perishing; even if the tread depth is adequate, tyres older than six years should be replaced regardless of mileage. Test the 12‑volt battery voltage and, if possible, conduct a load test, as long periods of inactivity can cause sulphation and reduced cranking power. Inspect all coolant, power‑steering and brake hoses for brittleness, and verify that the engine oil level is topped up and that there are no external oil leaks from the valve cover or oil filter housing. Finally, review the service book for evidence of regular oil changes, timing‑belt or chain service (if applicable), and ensure that any outstanding recalls have been addressed before committing to purchase.
