2015 BMW 740 3.0L Diesel · 10 YK

The most recent MOT on 17 August 2026 was passed with no recorded defects, indicating that the vehicle currently meets the statutory safety and emissions requirements. Over the past three years the MOT record shows a single failure for rear‑tyre tread depth in July 2024, which was remedied before the next test, and two advisories in 2023 concerning under‑tray obstruction and weak front brake reaction‑arm bushes. The progression from a failure to successive passes suggests that the owner has addressed the immediate safety issue and that the overall maintenance trend is stabilising rather than deteriorating. At 120,275 miles the 2015 BMW 740 averages just under 11,000 miles per annum, a usage pattern that sits comfortably within the typical range for a vehicle of this age. There are no obvious periods of unusually high mileage that would point to accelerated wear on high‑stress components such as the engine, transmission, or rear differentials. The relatively moderate annual distance also means that consumables are likely to have been replaced on a schedule rather than being driven to the point of catastrophic failure, but it does not preclude age‑related degradation of rubber and metal parts. Prospective buyers should verify that the rear tyres have been replaced or resurfaced since the 2024 failure and inspect all four tyres for uniform tread depth, sidewall condition, and any signs of cupping or separation that could indicate underlying suspension or alignment issues. The advisory about weak front brake reaction‑arm bushes warrants a tactile check of the front suspension for any play or clunking when the steering wheel is rocked at low speed; excessive movement may also manifest as a slight wobble under braking. Because the under‑tray fittings obscure components, request that the seller remove or lift the trays to allow a visual inspection of the exhaust system, fuel lines, and brake lines for corrosion or cracking, and to confirm that the brake calipers move freely without binding. Given the vehicle’s eleven‑year age, time‑based maintenance should be confirmed irrespective of mileage. Examine the 12‑volt battery for signs of sulfation or reduced cranking power, and consider a load test if the battery is original. Check the condition of the coolant, brake fluid, and power‑steering fluid, looking for discoloration, moisture ingress, or low levels that would suggest the need for a flush. Inspect the suspension bushings, especially the front control‑arm and rear trailing‑arm bushes, for cracking or excessive play, and ensure the brake discs are free from deep scoring or rust that could cause shudder. A thorough visual survey for rust on the wheel arches, chassis rails, and under‑body, particularly if the car has spent long periods stationary, will help identify any structural corrosion that could affect long‑term durability.
