2018 Mercedes-Benz GLA 2.1L Diesel · PO18 PZY

The vehicle is currently roadworthy, but the most recent test history indicates a lapse in proactive maintenance. While the car passed its MOT on 20 April 2026 at 83,785 miles, it failed earlier that same day due to multiple mechanical and electrical defects. The trend shows a stable period between 2023 and 2025, but the 2026 failure suggests that components were only addressed once they reached failure limits rather than during scheduled servicing. The mileage pattern is consistent with typical UK use for a premium SUV, averaging approximately 10,500 miles per annum. The progression from 54,296 miles in April 2023 to 83,785 miles in April 2026 shows a steady accumulation of roughly 9,500 miles annually recently. There is no evidence of long periods of standing or sudden spikes in usage, suggesting the vehicle has been used for regular road trips which generally helps prevent premature corrosion on underbody items like the braking system and suspension components. A buyer must conduct a close physical inspection of the rear braking system. The April 2026 failure flagged rear brake pads with less than 1.5mm of material and discs that were pitted and scored with corroded lips. While these were likely replaced to secure the pass, the buyer should verify that both sides were changed and that the calipers are not binding. The previous report of an inoperative Malfunction Indicator Lamp (MIL) is also a significant concern; the buyer should perform a diagnostic scan to ensure no hidden engine fault codes have been cleared simply to mask underlying performance issues. Final attention should be paid to the lighting and minor consumables. The discoloured rear indicators noted in the 2026 failure indicate UV damage or internal moisture ingress which can lead to failure. Given the age of the vehicle, the buyer should also check the rubber seals and wiper blades for cracking, as the previous advisory for a split wiper blade suggests that minor wear items are frequently overlooked by the current owner.
