2018 BMW 5 Series 4.4L Petrol · PL68 RTU

The most recent MOT, carried out on 30 April 2026, resulted in a full pass with no recorded defects, and this outcome mirrors the clean results recorded at each annual test since 2021. The consistency of passing without advisories suggests a stable maintenance regime, with no evident deterioration in the key safety‑critical systems that MOT inspectors evaluate. There is no indication of a worsening trend, and the absence of recurring faults points to either diligent servicing or limited operational stress on the vehicle. At eight years old the 2018 BMW 5 Series has accumulated only 34 369 miles, equating to roughly 4 300 miles per annum – well below the UK average for a vehicle of this class. Such low annual usage often reflects either predominantly short‑haul driving or periods of inactivity, both of which can influence component wear differently from high‑kilometre, long‑distance use. The modest mileage reduces the likelihood of fatigue‑related wear on the engine, transmission and suspension, but it also raises the possibility that the car may have spent extended periods stationary, which can promote rubber hardening, battery sulphation and corrosion in brake components. When inspecting a low‑mileage, lightly‑used BMW of this age, the buyer should give particular attention to tyre condition. Even with limited tread wear, tyre sidewalls can suffer from age‑related cracking, dry‑rot and loss of elasticity after six to eight years, especially if stored in a warm environment. Examine the tread depth, look for any visible cracks, bulges or foreign objects, and confirm that the tyres are within their recommended service life. The 12‑volt battery, although likely not heavily cycled, may have suffered from sulphation if the car has been idle for long stretches; a load test or a professional voltage check will reveal whether the battery can sustain a full charge under normal operating loads. Time‑based maintenance items also merit scrutiny. Verify that the engine oil and filter have been changed at the manufacturer‑specified intervals, and consider a fresh oil change if service records are incomplete, as oil can degrade chemically over time regardless of mileage. Inspect the brake discs and pads for surface rust, glazing or uneven wear, which can develop on vehicles that sit for months between journeys. Check for any signs of fluid leaks around the coolant, power‑steering and brake reservoirs, and ensure that these fluids are at the correct levels and appear clear, as old or contaminated fluids can compromise cooling and braking performance. Finally, confirm that the service book contains stamps for major scheduled services such as the timing‑chain or belt, suspension bushings and the air‑conditioning system, as these are key indicators that the car has been cared for in line with BMW’s service schedule.
