2016 Mercedes-Benz E 2.1L Diesel · WG66 GPK

The 2016 Mercedes-Benz E-Class presents a stable and improving maintenance trend, culminating in a fully clean pass on 21 May 2026 at 65,522 miles with zero defects recorded. That clean sheet is significant given the vehicle failed its prior test just two days earlier in July 2023 at 47,083 miles. On that occasion, the tester flagged structural tyre damage on both the offside front and offside rear, with inner and outer wall separation, alongside a parking brake efficiency deficiency. The subsequent tests in May 2024, May 2025, and May 2026 all passed without advisory or failure items, indicating those specific defects were rectified and have not recurred. The trajectory from a multi-defect failure to four consecutive clean passes suggests attentive remedial work and consistent upkeep in recent years. The mileage accumulation is broadly typical for a vehicle of this age, averaging roughly 6,552 miles per year over its ten-year lifespan. The recorded intervals show a steady progression: 47,086 miles in July 2023, 53,792 miles in May 2024, 59,422 miles in May 2025, and 65,522 miles in May 2026. Each annual increment sits between approximately 5,600 and 6,700 miles, with no sudden spikes or prolonged gaps that would raise concern about long-term standing damage or odometer anomalies. The consistent yearly accumulation points to regular road use rather than extended periods of inactivity, which reduces the likelihood of deterioration from seized components or stale fuel systems. Despite the clean recent record, the July 2023 failure warrants closer attention during any pre-purchase inspection. The structural tyre tears on the offside suggest the vehicle may have sustained kerb impact or pothole damage, which can also disturb suspension alignment and damage wheel rims. A buyer should have the front and rear suspension geometry checked, paying particular attention to the offside front lower arm bushes, track rod ends, and coil spring seating for any signs of distortion or cracking. The parking brake deficiency flagged in the same test should prompt a physical inspection of the rear calipers for sticking pistons, the handbrake cable for free movement, and the rear brake discs for uneven wear or lipping that could indicate a partially binding circuit. The absence of any advisories across the last four annual tests is encouraging for a vehicle approaching eleven years of age, particularly regarding exhaust emissions, structural corrosion, and braking performance. Still, a buyer should independently verify the condition of the subframes and inner wing arches for corrosion, test the operation of the electronic parking brake under load, and confirm that all four tyres are of matching specification with even tread wear. The MOT record confirms the car has been well maintained in recent hands, but the 2023 failure is a reminder that cosmetic and structural integrity checks remain essential before purchase.
