2007 Citroen C1 1.0L Petrol · NG57 VUT

Structural corrosion and braking instability define the current mechanical state of this vehicle, as evidenced by a failure and subsequent pass on 5 June 2024. While the earlier history was relatively clean, the most recent records show a downward trend in structural integrity, specifically regarding the front sub-frame and rear sills, alongside a major failure for fluctuating front service brakes. An average annual accumulation of approximately 4,995 miles is low for a vehicle of this age. Of particular note is a significant gap in the testing record between November 2020 and June 2024, suggesting the vehicle may have been stationary for a prolonged period. Such intervals of inactivity can often accelerate the onset of corrosion and lead to the deterioration of braking surfaces and rubber components, which aligns with the defects recorded upon its return to testing. A physical inspection should prioritise the areas flagged for corrosion, specifically the front sub-frame and the inner and outer sills on both the nearside and offside rear. While the 2024 test noted that structural rigidity was not yet significantly reduced, these are chronic areas of concern. During a test drive, pay close attention to the brake pedal for any vibration, judder, or inconsistent pressure, which relates to the previously recorded fluctuating service brakes and pitted discs. The exhaust system has a history of minor leaks and a deteriorated front hanger, which may manifest as an increased drone or audible rattling under acceleration. Check for any steering pull or unusual knocks when traversing uneven surfaces, as the corroded sub-frame can eventually impact the stability of suspension mounting points. Finally, ensure the windscreen wipers operate smoothly and clear the glass effectively to verify the rectification of the 2024 major failure.
