2014 BMW 640 3.0L Diesel · AF04 MAT

The most recent MOT, carried out on 10 October 2025, was passed with no recorded defects, indicating that the vehicle met the statutory safety and emissions standards at that time. Over the preceding six years the MOT record shows a mixed picture: two failures in 2020 and 2021 were driven by severe rear‑tyre tread loss and a slight wheel distortion, but since the 2022 test the car has passed each year, with only advisory notes concerning tyre tread depth. This progression suggests that the major safety concerns have been addressed and that the current maintenance trend is stable, albeit with tyre wear remaining a recurring issue that will need attention soon. At 109,276 miles on a 2014 model the average annual mileage works out at roughly 9,100 miles per year, which sits comfortably within the typical UK usage envelope for a twelve‑year‑old executive saloon. There are no obvious large mileage gaps that would imply prolonged periods of inactivity, so the wear observed on the tyres is more likely a function of normal road use rather than extreme low‑mileage ageing. Nevertheless, the relatively modest annual run‑off means that components such as the suspension bushes, engine mounts and brake discs may have been subjected to long‑term static loads, potentially accelerating corrosion or rubber hardening compared with a higher‑mileage, continuously driven counterpart. Prospective buyers should give the tyre situation priority. Both front and rear tyres have been flagged as being close to the legal limit and showing edge wear, which is a classic sign of mis‑alignment, worn camber/caster settings or uneven load distribution. On a test drive listen for a hollow or thumping sensation when cornering, and feel for any pull to one side that could indicate the need for an alignment or for replacement of the front camber bushes. Inspect the rims for the previously noted slight distortion, particularly on the nearside rear inner wheel, and verify that there is no vibration at higher speeds that would betray a bent wheel or damaged tyre bead. Given the age of the tyres, even if the tread depth is marginally acceptable, the rubber may be perishing; a visual check for cracking, dry rot or hardening of the sidewalls is essential before committing to purchase. Beyond the tyres, the buyer should assess the condition of the braking system, as brake discs on a vehicle of this age can develop surface corrosion or uneven wear, especially if the car has spent periods standing. Check for any pulsation or shudder when applying the brakes and inspect the pads for remaining thickness. The 12‑volt battery, now twelve years old, should be load‑tested to confirm it can hold charge, and the electrolyte level examined for signs of sulfation. All fluid reservoirs—engine oil, coolant, brake fluid and power‑steering fluid—should be examined for colour, clarity and correct level, with a view to replacing them if they have not been changed within the manufacturer’s time‑based intervals. Finally, a thorough visual inspection of the suspension components (coil springs, shock absorbers, bushings) and the under‑body for rust or corrosion will help confirm that the car has been kept in a dry environment and has not suffered hidden structural deterioration. A complete service book with recent stamps will further substantiate that the vehicle has received the requisite periodic maintenance.
