2022 Mercedes-Benz GLC 1.9L Diesel · AP22 SPP

The most recent MOT test conducted on the 2022 Mercedes-Benz GLC on 2026-02-10 resulted in a passing outcome, though it was accompanied by several critical advisories that warrant careful attention. The vehicle’s maintenance history shows a notable pattern of recurring tyre-related issues, with each MOT test since 2025 identifying front and rear tyres worn close to the legal limit or exhibiting uneven wear patterns, particularly on the edges. This persistence suggests either suboptimal alignment or incorrect tyre pressures, which can accelerate wear and potentially compromise handling and fuel efficiency. While the 2025 MOT was clean, the absence of defects in that test does not negate the likelihood of underlying wear progression, especially given the vehicle’s age and the consistent advisories. The advisories themselves are not failures but mandatory warnings that must be addressed promptly to prevent further deterioration or safety risks. The recorded mileage of 25,835 miles for a vehicle aged four years represents a reasonable annual usage rate of approximately 6,459 miles, which aligns with typical driving patterns for this class of car. However, the mileage data alone does not fully capture the vehicle’s operational history, as lower mileage could indicate periods of inactivity or light use, potentially leading to issues such as standing corrosion, particularly in the brake system or suspension components. Conversely, if the mileage accumulation was rapid or inconsistent, it might suggest more aggressive driving or exposure to harsh conditions, which could accelerate wear on suspension bushes, steering components, or exhaust systems. For this GLC, the absence of a detailed service history or odometer verification means the true extent of wear cannot be definitively assessed, but the advisories suggest that tyre management remains a priority. To proceed with a thorough inspection, the prospective buyer should prioritise checking the tyre condition beyond the MOT advisories. The front and rear tyres show signs of edge wear, which may indicate misalignment, incorrect tyre pressures, or camber angles that need correction. On a test drive, listen for any unusual noises from the front wheels, such as clunking or scraping, which could signal misaligned wheels or worn suspension bushes. Additionally, inspect the tyre tread depth and look for signs of uneven wear patterns that might suggest alignment or camber issues. Beyond tyres, the advisories do not extend to other critical systems, but the buyer should verify the vehicle’s alignment and wheel balance to mitigate further tyre wear and ensure safe handling. In terms of broader mechanical checks, given the vehicle’s age and the potential for standing corrosion, particularly in the brake system, the buyer should examine the brake discs and calipers for signs of corrosion, binding, or uneven wear. Standing for extended periods can lead to brake fluid degradation and potential moisture ingress, which may cause corrosion in the brake lines or calipers. The 12-volt battery should also be tested for health, as prolonged inactivity can reduce its capacity or lead to sulphation. Fluid levels, particularly the engine oil, differential fluid, and brake fluid, should be checked for contamination or degradation, with a recommendation to replace them according to the manufacturer’s service schedule, which for this model typically includes oil changes every 15,000 to 20,000 miles or every 12 months, whichever comes first. Lastly, the exhaust system and emissions should be inspected for leaks or structural integrity, as prolonged idling or standing can exacerbate corrosion in these components. If the vehicle has been driven regularly, the mileage advancements suggest it has likely undergone necessary servicing, but the buyer should confirm the presence of service book stamps for the recommended intervals, such as timing belt replacement (every 105,000 to 120,000 miles for this model) and suspension component checks.
