2009 Perodua Myvi 1.3L Petrol · SN09 CZC

The 2009 Perodua Myvi holds a valid MOT that passed on 12 May 2022 at 68,625 miles, but that certificate is now over four years old. The record reveals a worsening trend in corrosion-related brake system faults rather than a stable or resolving pattern. In the January 2020 test at 58,898 miles, the tester flagged excessively corroded brake pipes on both sides front and rear, including a pipe excessively damaged across the rear above the petrol tank area. That same test recorded a rear service brake imbalance that only just met requirements. By the May 2022 test at 68,625 miles, the tester still noted corroded brake pipes front to rear on both sides, now described as covered in grease or other material, alongside corroded rear coil springs and a light oil misting from the offside rear shock absorber. The recurrence of brake pipe corrosion advisories across the 2019, 2020, and 2022 tests indicates the corrosion issue has persisted and likely progressed rather than being properly remediated. The mileage profile is notably low for a 2009 vehicle. Between the January 2019 test at 53,071 miles and the May 2022 test at 68,625 miles, the car covered just 15,554 miles over roughly three years and four months, averaging around 4,400 miles annually in that window. The mileage then appears static between the May 2022 test and the current recorded figure of 68,625 miles, suggesting the vehicle has seen very little use or none at all since that last MOT. Such low annual mileage can mean reduced mechanical wear, but prolonged standing periods often accelerate corrosion in brake lines, fuel system components, and suspension bushes due to moisture accumulation and lack of heat cycling that would otherwise burn off surface moisture. A buyer should prioritise a thorough underbody inspection focusing on the brake pipe runs, particularly the rear section above the petrol tank area where the 2020 tester specifically noted excessive damage. Grease or other coatings on corroded pipes can mask the true extent of metal loss, so any visible surface corrosion on brake lines warrants close scrutiny and likely pressure testing. The rear suspension also demands attention, given the repeated advisories for corroded rear coil springs and a misting rear shock absorber. Corroded coil springs carry a risk of fracture under load, and a shock absorber showing oil misting is beginning to lose its damping efficiency. The rear brake imbalance flagged in January 2020 suggests a binding caliper or uneven wear on rear brake discs and pads, which should be verified through a rolling road brake test. Beyond the documented advisories, the extended gap since the last MOT means consumable components such as tyres, wiper blades, and fluid service history cannot be assumed current. The low-mileage pattern also raises the question of whether the cambelt has been replaced on schedule, as age rather than mileage drives rubber degradation on a 2009 engine. A pre-purchase inspection by a qualified mechanic, including a fresh MOT or comprehensive check, is strongly advisable before committing to this vehicle.
