2018 BMW 420 2.0L Diesel · YA18 YBN

The recent MOT history reveals a shift from an otherwise clean record to serious component failures, with the latest test in June 2026 flagging both front lower suspension arm pins or bushes as excessively worn – a major defect that would have rendered the car unsafe to drive until remedied. This follows a 2025 failure that declared a near‑side rear inner wheel fractured and exposed tyre cords on both rear tyres, a dangerous condition that required immediate replacement of the wheel and tyres. The pattern shows that while earlier years passed without recorded faults, the last two years have introduced critical wear and safety issues. At 67,658 miles recorded for a 2018 model, the average annual mileage sits around 8,500 miles, which aligns with typical usage for a vehicle of this age. The MOTs have been logged annually with no gaps, indicating the car has been regularly tested and any required repairs have been addressed to the point of passing. However, the mileage level means that wear items such as suspension bushings, brake pads and tyre carcasses are approaching the point where replacement is common, especially given the recent failures. For a prospective buyer, the front lower suspension arms should be inspected for play, clunking noises over bumps and any uneven tyre wear that could indicate degraded bushings. A test drive should include a careful listen for knocking or binding when turning the steering wheel at low speed and when applying the brakes, as worn arms can affect both handling and braking stability. The rear wheel fracture recorded in 2025 mandates a thorough visual check of the wheel rims for cracks, dents or repaired sections, and a tactile inspection of the tyre sidewalls for any signs of exposed cords or bulging that could precede another failure. Brake pad wear was noted as an advisory in 2025 and persists as a concern; the pads are likely close to the minimum thickness and should be measured and, if necessary, replaced before the next test. While the MOT passed after the advisory, the driver should feel for any pedal pulsation, increased stopping distances or squealing that would indicate the pads are nearing the end of their service life. A comprehensive brake system check, including disc condition and caliper operation, is advisable to ensure the braking performance meets safety standards before committing to purchase.
