2018 Mercedes-Benz GLA 2.1L Diesel · RF67 KWN

The most recent DVSA examination on 20 January 2026 recorded a clean PASS with no advisories or defects, which represents a positive immediate result. Looking at the trend across the recorded test history, the vehicle has demonstrated a generally stable maintenance profile, with clean passes recorded in 2022, 2023, and 2024, followed by an isolated failure in January 2025 that was rectified at the re-test later that same month. The two Major defects recorded at the 2025 failure related to perished anti-roll bar linkage ball joint dust covers on both front sides, while the advisories concerned a child seat obscuring seatbelt inspection and front tyre perishing. The clean January 2026 result suggests these specific concerns have been attended to, but the underlying mechanical context that produced them warrants careful inspection prior to purchase. The recorded mileage of 42,081 miles over approximately eight years equates to an annual average of around 5,260 miles, which is notably low for a vehicle of this age and indicates either predominantly short-trip usage or extended periods of standing between drives. This usage pattern has direct implications for mechanical condition; low annual mileage typically means the braking system, particularly the discs and callipers, may suffer from corrosion due to infrequent use, while the 12V battery is more likely to have suffered degraded capacity from chronic partial state-of-charge cycling on short journeys. Rubber components, drive belts, and hoses can also degrade calendar-based rather than mileage-based, meaning an eight-year-old vehicle should be evaluated on age-sensitive items regardless of the modest odometer reading. Given the advisory in 2025 regarding front tyre perishing on both sides, particular attention should be paid to the current condition of all four tyres and any recently fitted replacements; check the sidewalls closely for hairline cracking, dry rot, or crazing, particularly on the nearside front where UV exposure and age-related polymer degradation are most pronounced. On a test drive, listen for any knocking, rattling, or clonking over uneven surfaces, which could indicate that the perished anti-roll bar dust covers recorded at the 2025 failure allowed grit ingress and accelerated wear of the drop link ball joints themselves; even if replaced, the bushes or links may have been contaminated prior to renewal. Apply gentle steering inputs at low speed to detect any play or sloppiness through the steering rack, and listen for suspension creaks or thuds from the front axle over speed humps. Beyond the items flagged in the MOT history, a prospective buyer should conduct a thorough age-appropriate inspection covering brake disc surface condition for lip corrosion or pitting, caliper slide pin operation to confirm nothing is seizing from standing, and the condition of all undertray and suspension components for surface oxidation. Verify the service book history to ensure that brake fluid, coolant, and automatic transmission fluid (if applicable) have been changed on calendar-based intervals rather than purely mileage, as these fluids degrade hygroscopically and through additive depletion over time. Finally, request evidence of the recent front anti-roll bar repair to confirm quality components were used, test the air conditioning system for adequate cooling output as system seals perish with age on Mercedes-Benz vehicles of this generation, and check that the recent MOT pass reflects genuine maintenance rather than a minimum-standard preparation.
