2004 BMW 745 4.4L Petrol · LE51 ACE

The most recent MOT on 8 July 2024 was passed with no recorded defects, and the preceding test in April 2023 also returned a clean pass. Earlier MOTs show a gradual reduction in advisory items: 2022 highlighted slight play in the off‑side front track‑rod ball joint and minor rack‑gaiter wear, 2021 noted off‑side suspension arm ball‑joint play, and 2019 recorded a modest front lower oil leak. By 2020 the record was again clean, and the only earlier concerns were tyre wear and a corroded rear brake pipe in 2016. This pattern suggests that any earlier wear points have either been remedied or have settled, indicating an overall stabilising maintenance trend, though the persistence of ball‑joint advisories warrants close scrutiny. At 149,290 mi for a 2004 model the vehicle averages roughly 6,800 mi per year, which sits comfortably within typical UK usage for a car of this age. The relatively modest annual mileage implies periods of low utilisation or storage, which can be benign but also raises the possibility of age‑related degradation of rubber components, corrosion in concealed areas, and fluid breakdown. The mileage does not suggest excessive wear on major power‑train items, yet the combination of age and intermittent use means that consumables such as suspension bushings, brake discs and seals should be examined for hidden deterioration. When inspecting the steering and front suspension, pay particular attention to the off‑side track‑rod and drag‑link ball joints, the rack‑gaiter and associated dust covers, and the off‑side suspension arm ball joint. Look for any looseness when the wheel is rocked, audible clunking over bumps, or a vague wandering feel at steady speeds. Uneven front‑tyre wear, especially on the inner edges, can be a symptom of worn ball joints or mis‑aligned rack components. The front lower oil leak noted in 2019, though described as non‑excessive, should be verified by checking for oil spots around the valve‑cover gasket or oil pan and confirming that oil levels are stable; persistent leakage can lead to reduced lubrication of the timing chain or camshaft bearings over time. Given the vehicle’s age, a thorough age‑related check is essential. Examine all tyre sidewalls for cracking, dry rot or bulges regardless of tread depth, as ageing can render tyres unsafe even if mileage is low. Inspect the battery for sulphation and verify that it holds charge, especially if the car has spent long periods idle. Check the condition of the rear brake pipe for rust and ensure the brake pedal is firm with no sponginess, indicating that the brake fluid has been refreshed within the last two years. Finally, confirm that coolant, power‑steering fluid and transmission oil have been changed at appropriate intervals; any discolouration, debris, or foul odour points to the need for a fluid service before the car is relied upon for regular motoring.
