2003 Peugeot 307 1.4L Petrol · OY03 KFN

A persistent pattern of fluid leaks and exhaust defects dominates the roadworthiness record of this 2003 Peugeot 307, with multiple advisories and a major exhaust failure appearing across the recorded tests. The most recent assessment on 2023-02-21 recorded a pass, but it was accompanied by advisories for an oil leak, an engine coolant leak from the radiator, and a nearside front tyre worn close to the legal limit on its edge. Just six days earlier, the same vehicle failed on the same visit due to excessive exhaust carbon monoxide content, and a separate failed test in January 2022 recorded a major exhaust gas leak at the flange between the catalytic converter and centre section, alongside a non-functional headlamp and registration plate lamp. Across the available history there is one pass with no defects, one pass with a minor front exhaust leak advisory, and repeated mentions of exhaust integrity and fluid loss, indicating a chronic rather than incidental mechanical concern. The recorded mileage of 104,886 miles over approximately 23 years equates to around 4,560 miles annually, which is notably low for a vehicle of this age. Tests were conducted in 2018, 2019, 2020, 2022, and twice in early 2023, suggesting the car remained in regular use despite the modest annual mileage. Lower accumulation rates of this nature often reflect periods of light running or extended standing, which can produce their own mechanical consequences such as dried seals, surface corrosion on brake components, and deterioration of flexible hoses and gaskets, all of which would be consistent with the coolant and oil seepage advisories on file. Given the recurring oil and coolant leak advisories, a prospective buyer should inspect the engine bay closely for fresh oil residue around the cam cover, sump, and oil filter housing, and check the radiator, header tank, and hoses for staining, crusting, or evidence of recent top-ups. The coolant warning light behaviour should be observed during a cold start, and the header tank level checked with the engine cool. For the exhaust system, listen at idle for any ticking, blowing, or irregular exhaust note, particularly around the centre section and cat-to-pipe flange where the 2022 failure originated, and feel for any draught from beneath the car. Smoke from the tailpipe on a cold start or under load would warrant further investigation, particularly given the carbon monoxide exceedance recorded in 2023. The tyre advisory noting edge wear on the nearside front suggests an alignment or suspension geometry issue, so a test drive should include observation of any steering pull to one side, uneven steering return, or knocking or clonking from the front end over uneven surfaces. With the nearside rear slight brake bind advisory from 2019, the rear brakes should be checked for excessive heat after a short drive, and the nearside rear caliper and mechanism inspected for free movement. Given the vehicle's age and the pattern of fluid and exhaust defects, an inspection with the vehicle raised on a ramp is advisable to assess structural and underbody corrosion, as 23-year-old Peugeot 307s are known to suffer from rust around the rear axle, suspension mounting points, and sills, none of which would be visible from a standard ground-level appraisal.
