2015 Vauxhall Mokka 1.4L Petrol · SL07 MAT

A pattern of fluid leaks is the defining mechanical theme of this Mokka's recent MOT history, with coolant and engine oil seepage being flagged across both the 2025 and 2026 tests. The coolant leak is particularly noteworthy as it has persisted across two consecutive annual examinations, suggesting a deteriorating seal, gasket, or hose joint that warrants close inspection rather than dismissal as a minor advisory. The 2026 test also recorded a Major failure for a central rear seat belt not functioning as intended, which was rectified within four days before the vehicle passed; the underlying cause whether a seized retractor, a faulty latch mechanism, or a wiring issue with the buckle sensor should be verified, as seat belt integrity is a non-negotiable safety item. Beyond these concerns, the vehicle otherwise presents a broadly stable roadworthiness profile, with a clean pass recorded in 2024 and no structural corrosion advisories appearing in the record. With 107,570 miles accumulated over approximately eleven years, this Mokka has covered roughly 9,779 miles annually, which sits comfortably within typical usage parameters for its age. The mileage progression between tests shows consistent annual increments of around 10,000 to 12,000 miles, indicating regular rather than sporadic use, and there are no significant gaps in the testing record that would suggest prolonged periods off the road. This steady accumulation means the mechanical consumables such as brakes, tyres, suspension bushes, and drivetrain components have experienced normal wear cycles, and the advisories recorded are broadly consistent with a vehicle of this age and mileage rather than indicating any premature component failure. A prospective buyer should prioritise a thorough under-bonnet inspection to identify the source of the persistent coolant and oil leaks. For the coolant leak, check the condition of the water pump, thermostat housing, radiator, and the plastic coolant reservoir tank for signs of crystalline residue or staining, and listen for any unusual whining from the water pump bearings on startup. The oil leak, while not deemed excessive by the tester, should be traced to its origin commonly the valve cover gasket, front crankshaft seal, or oil filter housing on the 1.6-litre petrol and diesel units fitted to the Mokka, and the underside of the engine should be examined for fresh oil accumulation. On the test drive, monitor the temperature gauge closely for any upward creep and check the expansion tank level both cold and after a run, as a gradual drop would confirm an active coolant loss that needs addressing. The rear seat belt issue should be physically tested by a buyer before purchase, ensuring the central belt extends and retracts smoothly, the buckle latches securely with an audible click, and the inertia mechanism locks correctly under a sharp tug. Given that this Mokka is now well into its second decade and has crossed the 100,000-mile threshold, particular attention should be paid to the suspension on a test drive; listen for clonking or knocking noises from the front over speed bumps and uneven surfaces, which would indicate worn anti-roll bar drop links or bottom wishbone bushes common failures on this platform. The nearside front tyre was flagged as worn on the edge in 2025, so check for uneven shoulder wear which can point to alignment issues or worn suspension geometry. Finally, inspect the offside rear light lens for the damage noted in the advisories, ensure all rear lighting functions correctly, and verify that the rear registration plate remains clearly legible, as deterioration of these items can attract police attention even when technically within legal limits.
