2020 Mercedes-Benz GLB 220 AMG Line Prem D 4M A 1.9L Diesel · HO55 ANN

The most recent DVSA examination was conducted on 6 December 2025 and resulted in a pass with no defects or advisories recorded, which is the cleanest possible outcome for a vehicle of this age. Reviewing the broader history, the vehicle has passed every test since first presentation, with only minor items noted in earlier cycles, namely a windscreen chip in 2023 and wear-related advisories in late 2024 relating to tyre and brake pad condition. The absence of any advisories on the most recent test suggests that the previously noted wear items were addressed prior to the 2025 examination, likely as part of routine servicing or pre-test preparation. Overall, the maintenance trend appears stable and consistent, with no recurring defect patterns or structural concerns emerging from the DVSA records, which is a reassuring indicator for a prospective buyer. With a recorded mileage of 36,188 miles over approximately six years, the vehicle has been driven at an average rate of around 6,031 miles annually, which is broadly typical for a modern family SUV and consistent with a mix of urban, commuter, and longer-distance use. There are no apparent extended gaps between MOT tests that would suggest prolonged standing periods, nor any rapid mileage accumulation that would indicate heavy commercial or high-mileage operation. This moderate usage pattern tends to be favourable for mechanical longevity, as the drivetrain, turbocharging system, and four-wheel-drive components have been exercised regularly enough to avoid issues associated with extended idleness, whilst not being subjected to the accelerated wear typical of high-mileage vehicles. Given that the MOT history is largely clean with only wear-related advisories in 2024 and a minor windscreen defect in 2023, the buyer should focus on age-and-mileage-appropriate inspections rather than chasing specific recurring faults. The front and rear brake pads were flagged as wearing thin in late 2024, so although not recorded as defective in 2025, a physical inspection of pad material thickness, disk condition, and caliper operation is advisable. Listen for any brake shudder under firm application, which would suggest disc runout or uneven pad deposition, and check for any binding or juddering on a test drive, particularly from cold. Given the 2024 advisory of an offside rear tyre worn on the edge, particular attention should be paid to current tyre condition, including tread depth across the full width, sidewall integrity, and any uneven wear patterns that may hint at suspension misalignment or worn bushes, coil springs, or anti-roll bar links. Beyond the recorded advisory items, several time-based inspections are appropriate for a 2020 diesel Mercedes-Benz approaching six years of age. Diesel fuel systems are particularly sensitive to water contamination and microbial growth if the vehicle has stood for extended periods, so verifying recent fuel filter changes and checking for any hesitation or rough running on initial start-up is worthwhile. Brake fluid should be renewed every two years regardless of mileage, so the buyer should request evidence of when this was last carried out, along with confirmation of coolant and automatic transmission fluid servicing. The 12-volt battery should be tested for state of health, as auxiliary and start-stop systems place additional demand on the electrical system, and a failing battery can generate dashboard warning lights or cause electronic module irregularities. Finally, inspect the underside for any oil or coolant seepage from the turbo, intercooler piping, and rear differential, as these are common areas of concern on diesel four-wheel-drive platforms, and confirm the timing chain service interval status, as Mercedes-Benz diesel engines of this generation have known timing component wear considerations at higher mileages.
