2015 Mercedes-Benz GLA 2.1L Diesel · OY15 PDK

The defining feature of this GLA's MOT record is a recurring pattern of rear-axle and under-bonnet mechanical issues, with three of the four recorded tests since 2024 producing at least one advisory or failure, and both failures falling within a day of the vehicle being re-presented and passing cleanly. The most recent test on 26 March 2026 recorded a pass with no defects, which is positive, but the 25 March 2026 failure just one day earlier for a deep offside rear tyre cut exposing ply or cords is a significant safety finding. Combined with the March 2025 failure for an insecurely attached offside rear anti-roll bar linkage, there is evidence of rear-end component wear and degradation that has manifested across two consecutive test cycles. While the vehicle ultimately passed both times, a buyer should treat the pattern as indicative of rear suspension and wheel components that may now be approaching the end of their effective service life at this mileage. Against an age of eleven years, the recorded 107,599 miles equates to an annual accumulation of roughly 9,800 miles, which is broadly typical for a vehicle of this vintage rather than unusually low or high. There are no extended gaps in the MOT history that would suggest long periods off the road, with annual tests consistently recorded from 2024 through 2026, indicating the car has been in regular use. However, at this mileage on a Mercedes-Benz GLA, wear on consumable and chassis components such as coil springs, suspension arms, anti-roll bar drop links and bushes, brake discs and pads, and engine/transmission mountings should be considered expected rather than exceptional. Diesel or petrol variants in this class commonly show injector seepage, turbo actuator wear, and rear subframe corrosion by the time they pass 100,000 miles, even where MOT records do not yet formally flag them. Given the flagged offside rear anti-roll bar linkage failure, a physical inspection of the rear anti-roll bar, its drop links, and the surrounding bushes is strongly advised. On a test drive, listen for clonks or knocking from the rear over uneven roads and speed bumps, and feel for any vagueness or delay in the rear end responding to quick directional changes. With the offside rear tyre failure involving a cut exposing the cords, the offside rear wheel arch and surrounding bodywork should also be checked, as debris from corroded wheel arches or suspension components is a common cause of such cuts. Inspect the offside rear tyre sidewall closely for any bulges, and verify that replacement tyres are of matching size and load rating, with legal tread across the full width. More broadly, because this vehicle sits at a mileage where major service items are due, request evidence of recent replacement of brake fluid, coolant, spark plugs or diesel filters, drive belts, and any automatic transmission fluid changes if applicable. On the road, monitor for any steering vibration or pulling to one side under braking, which would point to warped front discs, and check for shudder or pulsing through the brake pedal. Listen for any timing chain rattle on cold start, particularly on petrol variants, and for any blue smoke from the exhaust under load on diesel models. Given the recurring rear-axle advisories and the very recent tyre failure, a pre-purchase inspection on a ramp by an independent Mercedes specialist would be a prudent investment to confirm the structural and mechanical integrity of the rear suspension and underside before committing.
