2010 Renault Megane 1.5L Diesel · ML10 UPP

A pattern of recurring front suspension and drivetrain wear dominates the mechanical history of this Renault Megane, with the most recent pass on 4 May 2023 accompanied by advisories for play in the offside front suspension arm ball joint and nearside front tyre damage. The trajectory is one of progressive deterioration rather than improvement. The 2019 test produced a dangerous defect for the front brake disc, described as seriously weakened, alongside major splits in both front CV joint boots. By 2020 both CV boots had failed again as major defects, paired with an excessively worn offside front lower suspension arm ball joint and an incorrect headlamp aim. A 2021 attempt failed on a non-functioning nearside rear stop lamp before a same-day pass. Across the following year the offside front anti-roll bar linkage ball joint, the offside front lower suspension arm ball joint, and the offside front outer drive shaft CV boot were all flagged, and by 2023 the offside front suspension arm ball joint had returned to the advisory list. The cumulative record points to chronic front-end component fatigue rather than isolated incidents. Against a sixteen-year age, the recorded 115,923 miles equates to roughly 7,245 miles per year, which sits close to the average for a vehicle of this vintage. Testing has been broadly annual, though there is a noticeable lapse between the March 2019 test and the April 2020 retest, and another between the May 2022 pass and the May 2023 pass, leaving the most recent entry now several years out of date at the time of writing. No mileage figures are listed on the MOT certificates themselves, so abrupt jumps or unusually low accumulation cannot be confirmed from the data, but the advisory for slight underbody corrosion in 2021 suggests age-related oxidisation has begun to take hold on the chassis structure, which is a relevant consideration on a car that has covered this sort of annual distance on UK roads. For a prospective buyer, the front suspension and drivetrain should be the primary focus of any inspection. The repeated ball joint advisories on the track rod ends, the anti-roll bar linkage, and the lower suspension arms indicate that the front suspension geometry is approaching the end of its service life. On a test drive, listen for clonking or knocking from the front wheels over speed humps and uneven surfaces, particularly from the offside, and feel for vagueness or rattling through the steering wheel when traversing broken tarmac. Jack the front and check for vertical and horizontal play in the wheels by hand, paying close attention to the lower arm joints and the track rod ends, as any free movement will confirm what the advisories have been suggesting for several years. The 2019 dangerous brake disc failure also warrants a physical check of the front discs for lip, runout, and corrosion pitting, and the pedal should feel firm without judder under hard braking. The CV joint boots require equal scrutiny. Both inner and outer boots on both sides have been flagged as either severely deteriorated or split on three separate occasions between 2019 and 2022, meaning grease loss and subsequent joint wear are likely candidates. With the steering on full lock at low speed, listen for clicking or a binding sensation from the front hubs, which would indicate worn CV joints rather than simply perished boots. Inspect the boots themselves for fresh grease deposits, cracks, or perished rubber. The 2021 stop lamp failure is a minor electrical item but worth confirming during a walk-around, and the 2020 headlamp aim defect should be rechecked by a garage to ensure beam pattern and alignment are correct. Given the mileage, the age, and the underbody corrosion advisory, a thorough ramp inspection is advisable to assess structural integrity and exhaust condition before purchase.
