2016 Vauxhall Mokka 1.6L Diesel · SD66 AAV

The most recent MOT on 9 July 2026 was passed with no recorded defects, but the pattern of advisories over the last five years shows a gradual increase in corrosion‑related observations. In 2022 and 2023 the tests were clean, while 2024 introduced advisories on both front and rear sub‑frames, and 2025 added notes on rear springs and their mounting points. Although none of these issues have yet breached the safety thresholds, the trend suggests that corrosion is progressing and should be monitored closely. At ten years old the Mokka has logged 59,023 mi, which works out to roughly 5,900 mi per annum – well below the typical UK average of 10‑12 000 mi per year. Such low utilisation often points to periods of limited use or extended storage, both of which can exacerbate under‑body rust and the degradation of rubber components. The mileage itself does not raise immediate concerns about wear on the engine, transmission or drivetrain, but the combination of age and low use means that time‑related deterioration may be more significant than mileage‑related wear. When inspecting the vehicle, give particular attention to the front and rear sub‑frame areas and the rear spring mounting points for any signs of surface rust advancing to flaking or pitting, especially around welds and bolt holes. On a test drive listen for clunking or squeaking when navigating bumps or applying the brakes, which could indicate weakened spring mounts or deteriorating bushings. Check the rear suspension for uneven tyre wear that might betray mis‑alignment caused by corroded mounting brackets, and verify that the rear springs are free of cracks or excessive corrosion that could affect ride height or handling. If any of these symptoms are present, budgeting for a thorough under‑body treatment and possible replacement of affected suspension components would be prudent. Given the vehicle’s age, also examine the tyre sidewalls for cracking, dry rot or hardening, as tyres can perish after six years regardless of tread depth. Test the 12‑volt battery for voltage under load and look for signs of electrolyte leakage or terminal corrosion, especially if the car has spent long periods idle. Inspect brake discs for surface rust or scoring and ensure the calipers move freely without binding; fluid should be flushed if it appears dark or if the service interval has been exceeded. Finally, confirm that the service book contains regular oil, filter and coolant changes, as calendar‑based fluid degradation can affect engine reliability even on a low‑mileage vehicle.
