2016 Citroen C1 1.2L Petrol · GD16 AVM

The defining mechanical story of this 2016 Citroen C1 is a progressive accumulation of wear-related advisories and a pattern of intermittent brake-related failures over the past three MOT cycles. The most recent test on 10 April 2026 produced both a pass and a fail on the same day, with the failure attributed to an offside rear service brake excessively binding, while both records carry advisories for a pitted front brake disc and subframe corrosion. This follows a 2025 test where front brake imbalance, both front brake discs pitted, a noisy offside front wheel bearing, and the same subframe corrosion advisory were all flagged, and 2024 and 2023 cycles where exhaust joint leaks, suspension arm bushes, and parking brake problems appeared repeatedly. The trend is one of an ageing vehicle with multiple component groups wearing concurrently, with the parking brake and rear brake mechanism being the most recent functional failures rather than isolated events. Mileage of 85,423 over ten years equates to roughly 8,500 miles annually, which is broadly typical for a small city-oriented car of this age. There are no significant gaps in the testing record, with annual MOTs consistently carried out from 2022 through 2026, indicating continuous use on the road. Given the annual mileage, wear on consumables such as brake discs, pads, and suspension components is consistent with what one would expect for a C1 of this vintage, and the advisory pattern largely reflects that normal progression rather than any unusual usage intensity. The absence of recorded mileage on the earlier MOT entries makes it impossible to verify whether there were any large single-year jumps, but the steady testing cadence supports a working vehicle rather than one with extended periods off the road. For a prospective buyer, the front brake discs and the front subframe corrosion deserve close physical inspection. On a test drive, listen for scraping, grinding, or pulsation through the brake pedal when pulling away from low speed, as pitted front discs will typically produce a brake judder under heavier braking and may also generate a squealing noise. The advisories indicate the corrosion is not yet serious, but subframe rust on a C1 of this age can advance quickly, particularly around mounting points and suspension attachment areas, so a thorough examination on a ramp for any flaking, bubbling under paint, or thinning of the metal is worthwhile. The rear brake binding issue recorded at the 2026 failure is particularly relevant and should be checked by attempting a rolling hill start in reverse on a slight incline; if the offside rear caliper or mechanism is sticking, the car will either refuse to roll back freely or will drag noticeably when moving off. The rear parking brake also failed in 2023 and 2024 before passing in 2025, so confirming that it holds firmly on a slope and that the lever or electronic mechanism operates cleanly is essential. Further checks should focus on the exhaust system, given advisories in 2023 and 2024 for a leaking joint between the middle and rear sections and a defective front mounting. With the engine running from cold, listen for any ticking, hissing, or blowing sounds emanating from beneath the car, particularly at the flexible joint and mounting rubbers, as deteriorated exhaust mounts can allow the system to move under acceleration and cause further joint stress. The suspension arm bushes noted as worn in 2023 should be evaluated by pushing laterally on each front corner with the wheels on the ground to detect any knocking or looseness, and by driving over speed bumps to listen for clonking from the front end, which would indicate the bushes have deteriorated beyond advisory levels. Finally, the offside front wheel bearing that was noted as slightly noisy in 2025 should be assessed at road speed with the windows down; a growling or humming that changes with cornering suggests the bearing has worn further and may soon require replacement.
