2022 Mercedes-Benz GLC 1.9L Diesel · D14 BAA

A clear mechanical theme emerges from the DVSA record of this 2022 Mercedes-Benz GLC: a repeating pattern of rear tyre wear advisories on consecutive MOT tests, with no other structural, brake, suspension, or corrosion items flagged across the testing period. Both the 2025-06-26 and 2026-06-22 tests returned pass results, and the only defects noted were near-side and off-side rear tyres recorded as worn close to the legal limit on edge at 3.0mm tread depth. The fact that the same pair of tyres was flagged in two successive tests indicates an ongoing geometry or loading characteristic rather than a one-off wear event, and any prospective buyer should treat this as a recurring cost line rather than a single intervention. At 35,647 miles over four years, this GLC is accumulating around 8,900 miles annually, which sits comfortably within the typical bracket for a privately used SUV of this age and class. There are no unexplained gaps in the MOT sequence and no large mileage jumps between tests that would suggest inconsistent record-keeping or a change in usage pattern. Mechanically, this kind of steady, moderate mileage is favourable for the major drivetrain and underbody components, as the vehicle has not been left standing for long periods yet has not accumulated the high-mileage wear that typically accelerates suspension bush deterioration, brake disc lipping, or dual-clutch or automatic transmission fluid degradation. Given the recurring rear edge-wear advisory, a test drive should include careful attention to the rear axle geometry. Listen for any humming or drone from the rear tyres that increases with speed, as this often accompanies uneven shoulder wear, and feel for any steering wheel disturbance or rear-end instability under braking that could indicate a contributing alignment issue. Inspect the rear tread pattern closely with the wheels on full lock to confirm whether the wear is concentrated on the inner or outer shoulder, and check the sidewalls for any feathering that would point to a toe or camber fault. It is also worth asking for evidence of a recent four-wheel alignment, as the same advisories appearing a year apart strongly suggests a persistent set-up issue that has not yet been corrected. Beyond the flagged tyres, this is a good opportunity to verify the general underfloor and chassis condition on a raised inspection, particularly the rear subframe mounting points, coil springs, and anti-roll bar bushes, as these are common wear items on GLC-Class vehicles of this generation and have not yet been recorded by the tester. With the engine running from cold, listen for any timing chain rattle, turbo whistle, or excessive vibration through the steering column, and confirm that the 9G-Tronic automatic transmission changes smoothly without harshness or flare between ratios. A scan for any stored drivetrain fault codes is advisable even though no dashboard warning lights are implied by the MOT history, giving a complete mechanical picture before purchase.
