2019 DS DS3 1.2L Petrol · KT19 CEN

The 2019 DS DS3 currently holds a valid MOT following a pass on 2026-06-06 at 39,067 miles, though the maintenance trend shows a recent decline. The vehicle failed its initial test that same day due to a dangerous offside rear tyre cut reaching the ply and a perishing nearside rear tyre, requiring immediate replacement before the retest. While the electronic parking brake system failed catastrophically in May 2025, the June 2025 test confirms it was rectified, suggesting a prior intermittent electrical fault was addressed. The overall pattern reveals a history of resolving mechanical issues, yet the sudden failure on basic tyre condition points to a recent lack of routine checks. Accumulating 39,067 miles over seven years equates to a low annual average of roughly 5,581 miles. The mileage progression shows a gap of 3,817 miles between June 2024 at 29,593 miles and May 2025 at 33,410 miles, before rising to 5,657 miles over the subsequent twelve months leading to the June 2026 test. Such low mileage often implies extended periods of standing, which directly explains the perishing and cracking observed on the rear tyres. Long stationary periods cause rubber to degrade and flat-spot, meaning the recent tyre failures likely stem from age-related deterioration rather than high wear rates. A physical inspection must scrutinise the electronic parking brake operation, given the complete system failure recorded in May 2025. Although the June 2025 pass confirms a repair, the underlying cause—whether a faulty actuator, corroded wiring, or module issue—warrants a thorough diagnostic scan. The tester flagged the front brake discs as worn and pitted in June 2024, so checking their current thickness and condition is essential to ensure they have not deteriorated further. Given the low mileage and likely long stationary periods, examine the suspension bushes and coil springs for deterioration, and assess all remaining tyres for age-related cracking beyond the two recently replaced.
