2016 Mercedes-Benz A-Class 1.5L Diesel · PO66 XOD

The vehicle achieved an MOT pass on 21 June 2026, having previously failed the same day on a windscreen washer fluid defect, which was rectified and noted under the PRS category. While the latest test was successful, the advisory notices concerning front and rear brake discs worn, pitted, or scored on both sides are worth noting. Although neither advisory was deemed serious enough to fail the vehicle, the bilateral nature of the wear suggests that the braking system has reached a stage where disc refurbishment or replacement should be anticipated within the near future. Looking at the broader history, the maintenance trajectory shows a mild downward trend, with recurring brake-related advisories in 2024 and 2026, a near-limit inner rear tyre in 2024, and a dangerous front brake pad failure on the same test. This pattern suggests that consumable wear items are being addressed but the owner may be running components closer to their service limits than ideal. A buyer should not regard the pass as evidence of a fully refreshed braking system. With 63,734 miles recorded against a ten-year vehicle age, the annual mileage averages around 6,373 miles, which is broadly typical for a car of this vintage. There are no unusually large gaps between MOT tests in the recorded history, indicating the vehicle has been in consistent use rather than left standing for extended periods, which is generally favourable for preventing calendar-based degradation. The mileage progression from 2020 onwards appears steady and proportionate, with no signs of clocking or erratic accumulation. That said, moderate annual mileage on a ten-year-old Mercedes-Benz A-Class means that wear items such as suspension bushes, coil springs, engine and gearbox mounts, and drive belts will have experienced consistent fatigue cycles and should be physically inspected rather than assumed sound purely on the basis of odometer reading. A prospective buyer should place particular emphasis on the braking system given the documented history. The 2024 dangerous failure for front brake pads below 1.5 mm was rectified at the same test, but the reappearance of brake disc pitting and scoring on both axles in 2026 suggests that pad wear has been aggressive or that the discs themselves were not replaced alongside the pads, allowing corrosion and wear to recur. On a test drive, listen for any brake shudder through the steering wheel or pedal under moderate stopping, which would indicate disc runout or uneven surface wear, and feel for any pulling to one side under braking. Inspect the discs visually through the wheels for a pronounced lip on the outer edge and check for any binding calipers by driving briefly then touching each wheel hub to confirm even warmth. The nearside rear inner tyre advisory in 2024 also warrants a check of current rear axle geometry, as inner-edge wear on a single side can indicate camber misalignment or worn rear suspension components. Beyond the documented items, the age and mileage profile of this vehicle call for several additional inspection points. Tyre sidewalls should be examined for perishing or cracking, particularly on any tyres that may have been fitted for several years regardless of tread depth, and the manufacturing date code should fall within the last few years to avoid age-related rubber degradation. Given that the car is a decade old, the 12V battery health should be verified by measuring resting voltage and testing the alternator output, as Mercedes-Benz electrical systems are sensitive to voltage irregularities. Brake fluid, coolant, and transmission fluid should be considered overdue on a calendar basis if service history cannot confirm recent replacement, and a fluid inspection via the dipstick or reservoir colour will give an indication of servicing intervals. Finally, examine the underside and wheel arches for corrosion, which can be a concern even on well-maintained vehicles of this age, and verify that the service book and digital service records corroborate the mileage and any reported repairs.
