2017 BMW 420 2.0L Diesel · X13 MAA

The vehicle currently holds a PASSED MOT status from 21 October 2025 at 103 900 miles, yet the maintenance trend shows a gradual decline. The most recent test recorded rear tyres worn close to the legal limit (5.2.3 (e)), echoing earlier front‑tyre advisories and a 2023 failure for rear shock fluid leakage (5.3.2 (b)). Brake‑related entries also accumulate: slight disc corrosion, pad thinness, and a service‑brake fluctuation in 2023. While the latest test is clean, the recurrence of tyre wear and the unresolved suspension issue indicate a worsening condition rather than improvement. Mileage progression aligns with typical usage for a nine‑year‑old BMW 420, averaging roughly 11 500 miles per year. MOT entries are annual, with a brief COVID‑19 six‑month extension noted in April 2020. The gap between the May 2023 pass (70 512 miles) and the October 2023 failure (74 421 miles) reflects rapid deterioration over a five‑month period, suggesting that wear accelerated during that interval. The most recent test falls about ten months before the current date of 7 August 2026, keeping the record within a year’s horizon. A prospective buyer should inspect the tyre condition closely: verify tread depth, look for edge wear on both rear tyres, and search for bulges or structural separation, especially on the front tyres where past failures occurred. The rear shock absorbers must be examined for fluid leaks; any oil staining indicates compromised damping. Brake discs should be checked for corrosion lip and surface uniformity, while pads need measurement against wear limits. Test the brake pedal for fluctuation and listen for caliper binding. Suspension bushes and coil springs merit visual inspection for corrosion or wear. Finally, assess the underbody for rust, noting that no structural corrosion has been recorded but regular checks remain prudent. In summary, the BMW 420 is roadworthy at present but requires immediate attention to the rear tyres, rear shock, and brake components. Budgeting for tyre replacement and a full brake‑system refresh will be essential to maintain safety and preserve the vehicle’s remaining service life.
