2016 BMW 435 3.0L Diesel · DP16 DLD

The most recent MOT, carried out on 6 July 2026, resulted in a failure on account of dangerous bulges in both the off‑side and near‑side front tyres, while also recording a minor fault with the off‑side wiper blade and an advisory for play in the steering‑rack inner joint. Over the past three years the pattern has moved from a clean pass in July 2025 to a series of advisory‑heavy results in 2024 and now a dangerous tyre failure in 2026, indicating a clear deterioration rather than a stabilising maintenance trend. At 118 502 miles the car averages just under 12 000 miles per annum since its 2016 registration, which sits comfortably within the typical UK usage envelope. The mileage does not suggest excessive wear from high‑kilometre abuse, but the presence of tyre bulges and suspension‑arm bush wear at this mileage points to either aggressive cornering loads or periods of standing that have allowed structural fatigue to develop earlier than might be expected for a vehicle of this age. Prospective buyers should give immediate attention to the front tyre condition. The bulges are a sign of internal ply separation and can precipitate a rapid loss of pressure or a catastrophic blow‑out; the tyres must be removed, inspected on a dismounting rig and replaced without delay. While inspecting the wheels, check for uneven tread wear, sidewall cracking from age, and ensure the wheel nuts are torqued to BMW specification. The advisory on steering‑rack inner joint play should be felt as a vague looseness or vague wandering when steering at low speed; a qualified technician should measure the rack clearance and, if beyond the permissible limit, replace or rebuild the rack to avoid future steering‑rack failure. The suspension‑arm pin and bush advisories, although not yet causing excessive movement, are likely to develop into clunking noises or altered camber as the rubber degrades; a thorough visual inspection of the control‑arm bushings for cracks, oil staining or excessive play, followed by a road test listening for knocks when hitting bumps, will reveal whether replacement is imminent. In addition to the tyre and steering concerns, verify that the wiper blade is correctly seated and the blade itself is not cracked, as poor visibility can mask other faults. Given the vehicle’s ten‑year age, inspect the 12 V battery for sulphation and confirm it holds charge under load, check the brake discs for surface rust or glazing and ensure the calipers move freely without sticking, and confirm that all service‑book entries show timely oil, filter and coolant changes – fluids degrade over calendar time even when mileage is modest. A comprehensive visual check of the under‑body for corrosion, especially around the rear subframe and exhaust hangers, will also help to rule out hidden structural deterioration before committing to purchase.
