2021 Ford Transit 350 Leader Ecoblue 2.0L Diesel · WP21 AGV

The 2026‑01‑30 MOT at 86,662 miles resulted in a failure, the sole defect being off‑side rear tyre tread depth below the 1.6 mm legal limit, confirming that the vehicle is currently not road‑legal. Repeated tyre wear and a rear differential front‑seal leak recorded at earlier dates show a pattern of deteriorating condition rather than stable upkeep. The mileage trajectory is high for a five‑year‑old Transit, averaging about 17,300 miles per year. Accumulation accelerated sharply between June 2024 (71,030 mi) and January 2025 (81,517 mi), a gain of over 10,000 miles in seven months, before settling to a slower increase to the latest test. A buyer should therefore focus on the rear tyre condition, checking for uneven wear or damage, and inspect the rear suspension bushes and coil springs for wear or binding. The rear brakes, which were flagged for binding in earlier records, merit a close examination of calipers, discs and pads. The rear differential oil leak at 71,030 mi suggests a potential seal failure that should be verified, and any signs of structural rust or exhaust corrosion must also be assessed. Given the recurring tyre and mechanical faults, the purchaser ought to prioritize replacement of the rear tyre, confirm the integrity of the braking system and suspension components, and verify that the differential leak has been rectified before committing to the purchase.
