2018 Renault Clio 0.9L Petrol · YC18 DBB

The defining mechanical concern across this Renault Clio's MOT history is a clear and progressive pattern of brake pipe corrosion affecting the offside front line, which has been flagged at every annual test since 2023 and is joined by nearside front pipe corrosion from 2024 onward. While the 2026 test on 30 July was passed with only a single advisory, the recurrence of the same grease-covered, corroded front brake pipe advisories across four consecutive tests suggests an underlying deterioration that has not been resolved through component replacement. Adding to the longer-term picture, the 2024 test recorded advisories for corrosion on both rear coil springs, and the 2025 test identified three tyres worn close to the legal limit or on edge, indicating that consumable wear and chassis component degradation are both advancing. Most notably, the 2021 test resulted in a dangerous failure for tyres with exposed ply or cords on the offside front and nearside rear, demonstrating that the vehicle has a confirmed history of component neglect reaching a safety-critical threshold at least once in its life. With 65,049 miles recorded over approximately eight years, annual usage averages around 8,131 miles, which sits within typical parameters for a car of this age and is neither notably low nor high. There are no significant gaps in the testing record, with annual MOTs conducted consistently from 2021 through 2026, indicating the vehicle has remained in regular use rather than being laid up for extended periods. The mileage progression between tests appears steady and proportionate to the annual accumulation rate, suggesting no abrupt change in driving pattern that might indicate a long motorway commute or a sudden increase in use. At this average annual mileage, wear on suspension components, brake friction material, tyres and underbody metal is to be expected, which aligns with the recurring advisories observed in the record. For a prospective buyer, the brake pipe corrosion is the primary area requiring attention. The offside front brake line has been flagged at four consecutive tests, and although grease or other material has kept the corrosion suppressed enough to pass, the underlying steel is likely thinning and will eventually require replacement to avoid a future failure. On inspection, the underbody should be raised and the front brake pipes examined for pitting, flaking, or swelling at joints and mounting clips, and on the road the brakes should feel firm without any sponginess or excessive pedal travel that could indicate a slowly weeping line. The 2024 advisories for both rear coil springs being corroded also warrant visual inspection; listen for any knocking from the rear suspension over uneven surfaces and check for sagging at the rear when the car is unladen, as corroded springs can weaken and fracture over time. The tyre wear pattern should also inform a physical check. With advisories recorded on three tyres in 2025 and a prior dangerous failure for exposed cords in 2021, fitment quality and rotation history are relevant. On a test drive, the steering should not pull to either side, and there should be no vibration through the wheel that might indicate uneven wear or a damaged sidewall. The nearside rear brake pipe has not been flagged alongside the front lines, but given the pattern of front corrosion, it is sensible to inspect all visible underbody brake lines for early signs of surface degradation. Finally, a thorough road test should include firm braking from speed to confirm straight-line stability and the absence of any judder that might suggest worn discs, particularly given the cumulative mileage on the front brake system.
