2006 Peugeot 107 1.0L Petrol · YP56 DFU

A twenty-year-old Peugeot 107 with four recorded MOT failures across six tests presents a mixed roadworthiness picture dominated by repeat defects rather than isolated incidents. The most recent outcome on 15 February 2023 was a pass, but it emerged immediately after a same-day failure for severely reduced headlamp light intensity, and it carried a continued advisory for pitted and corroded front brake discs that has now persisted across three consecutive tests. The 2021 test pass was similarly bookended by a major-defect failure six days earlier for a leaking rear shock absorber and an inoperative horn, and the 2020 cycle also featured a major-defect failure the day before its pass, this time for a cluster of electrical and wiper defects. Taken together, the record demonstrates a pattern where the vehicle frequently enters the test bay with multiple defects live, only just clearing the threshold on the retest. With 160,218 miles accumulated over two decades, this example averages roughly 8,011 miles per year, which sits within typical parameters for a city-focused Peugeot 107 of this vintage. However, the testing cadence reveals stretches of irregular use: gaps of well over a year between some tests, and the mileage accumulated between recorded events is substantial. Mechanically, this combination of moderate annual mileage and high absolute mileage is consistent with the wear pattern visible in the record, where consumables such as brake discs, tyres, suspension bushes, and shock absorbers have all reached the threshold of advisories or failures. The catalytic converter and exhaust system also produced a carbon monoxide exceedance and an emissions-affecting exhaust leak in 2019, suggesting the rear exhaust advisory from the same test may have been a precursor to more significant emissions deterioration that should not be assumed resolved. The front brake disc pitting and rusting flagged on both the 2021 and 2023 advisories is a mechanical priority, as these discs have been on a watch list for two test cycles and may now be approaching the minimum thickness. On a test drive, listen for any grinding or pulsation through the brake pedal under firm application, and check for pull to one side that could indicate a binding caliper or uneven disc wear. The 2021 advisories for worn rear beam bushes and front anti-roll bar linkage bushes point to degradation in the secondary suspension; on uneven road surfaces, expect to hear clonking or knocking from the rear axle, and the body may shift laterally over sharp inputs. The 2020 lower suspension arm ball joint dust cover advisory also warrants close inspection, as perished dust covers accelerate joint wear, so feel for any vagueness or rattle from the front suspension when traversing speed bumps. The 2021 nearside rear shock absorber fluid leak is a particular concern given the age of the component and the fact that no subsequent test data confirms replacement. On test, perform a series of brisk left-right weight transfers over undulating tarmac to expose any extension damping loss, which can manifest as the rear continuing to oscillate after a bump or a pronounced rear-end squat under braking. The repeated major defects for the horn, wiper effectiveness, headlamp output, and indicator function across 2020, 2021, and 2023 suggest electrical and trim integrity should be scrutinised carefully, as the 107 is known for brittle wiring and aged switchgear. Finally, given the exhaust leak advisory from 2019, inspect the rear silencer and joint for soot deposits and listen for a ticking under load, and verify that the emissions warning light on the dashboard behaves correctly, as a recurrence of the 2019 carbon monoxide exceedance would likely now constitute a failure.
