2006 Citroen C1 1.0L Petrol · LR06 OYA

A pattern of recurring advisories and several major defects has emerged across this Citroën C1's recent MOT history, with the most recent pass on 23 December 2024 accompanied by two advisories despite clearing all categories on that occasion. The overall trajectory is mixed rather than reassuring: a clean pass in December 2023 was preceded by a failure just three days earlier involving headlamp aim, parking brake efficiency, and a rear position lamp, while a subsequent retest in December 2024 followed a failure six days earlier that included both headlamps with incorrect beam images, a major exhaust leak at the front pipe, and an inability to complete the emissions test due to that leak. The persistence of headlamp aim issues across two separate test attempts is particularly notable, as is the exhaust system breach that compromised the emissions check. Combined with the advisory on nearside front shock absorber oil misting carried from the failure into the pass, the record indicates a vehicle with active wear items developing rather than one with a stable roadworthiness profile. With 131,450 miles recorded over twenty years, this C1 has covered roughly 6,572 miles per year on average, which sits broadly in line with what one would expect for a city-oriented vehicle of this age. The mileage progression across the recorded tests does not show any dramatic spikes or extended standing periods that would suggest unusual use, and there is no evidence in the MOT record of multi-year gaps that might raise concerns about dormant component deterioration. At this accumulated mileage, however, consumables such as brake components, exhaust mountings, and suspension dampers will have done considerable work, and the failure history recorded here aligns with that expectation. For a prospective buyer, the front exhaust pipe joint is the single most pressing item to inspect, given the major leak recorded in December 2024 and the consequential inability to complete the emissions test. On a cold start, listen for a pronounced ticking or hissing from the front section that would indicate a blown gasket or cracked flexi joint, and check for soot deposits around the joint. The nearside front shock absorber, flagged for light oil misting at both the December 2024 failure and pass, should be examined for any progression; on a test drive, pay attention to a clonking noise or excessive bounce over uneven surfaces, which would suggest the damper seal has deteriorated further since the advisory was issued. Uneven tyre wear or steering pull could also indicate the strut is no longer damping effectively. Headlamp aim has now appeared as a major defect on three separate occasions within the recorded history, on both nearside and offside units, which warrants particular attention given that two of these were recorded in the same calendar year. Inspect the headlamp adjusters for stripped threads or broken mounting lugs, as this is a common reason beam images cannot be correctly set on this model, and confirm that both lamps hold their position when the bonnet is closed. The parking brake efficiency failure in December 2023 should be verified by testing the lever travel and holding force on a slope; if the lever requires excessive pull or fails to hold the vehicle, the rear cable or drum mechanism adjustment will need attention. Finally, the rear tyre condition flagged in December 2022, including cracking and perishing on the offside outer wall, should be rechecked regardless of tread depth, as aged sidewall rubber on a high-mileage car can degrade further and present a failure risk at the next test.
