2015 Mercedes-Benz GLA 2.1L Diesel · SM65 AAF

The vehicle’s most recent MOT test on 2026-01-17—just six months ago—confirms a clean pass with no defects recorded, though the record also shows a duplicate entry for the same date and mileage (78,334 and 78,337 miles), which may indicate a minor administrative oversight rather than a mechanical issue. The absence of advisories or repeated failures across all five MOT tests suggests a stable maintenance history, with no evidence of worsening structural or mechanical concerns. However, the repeated pass/fail entries at the same mileage in January 2026 warrant scrutiny to confirm whether this was a genuine retest or a data error, as it deviates from the otherwise consistent pattern of annual testing. The mileage progression of approximately 7,100 miles per year aligns with typical usage for a vehicle of this age, with no abrupt spikes or prolonged inactivity. The most notable gap is between the 2023 and 2024 tests, where mileage increased by 7,525 miles in just over a year, indicating active use rather than neglect. There are no red flags in the intervals between tests, and the lack of advisories or failures over the past decade implies that basic servicing—such as brake pad replacements, fluid changes, and tyre rotations—has likely been attended to, though this cannot be confirmed without service records. Given the clean MOT history, the primary focus for an in-person inspection should centre on high-wear components that are not directly tested under MOT but critical for long-term reliability. The suspension system, particularly the rear coil springs and bushes, should be examined for uneven wear or corrosion, as Mercedes-Benz GLAs are prone to bush deterioration over 100,000 miles. Brake calipers and discs should be checked for binding or excessive lateral wear, especially if the vehicle has been driven aggressively, as the MOT does not test for uneven pad thickness or disc warping. Additionally, the subframe and rear axle area should be inspected for signs of corrosion or structural fatigue, particularly if the vehicle has been exposed to salted roads or off-road use. The exhaust system’s integrity should also be verified, as catalytic converter failures or leaks are common in this model and often go unnoticed until emissions tests fail.
