2010 BMW 5 Series 2.0L Diesel · WN60 WCM

The 2.0-litre diesel 5 Series from this era typically returns 45 to 55 mpg on a cruise, though real-world mixed driving usually lands closer to 40 to 45 mpg. Road tax sits in a higher bracket than smaller diesels, and insurance for an executive saloon of this age will be moderate rather than cheap, particularly for younger drivers. Servicing at a BMW specialist is advisable, and at this mileage major items such as timing chain (on the N47 engine), turbo, injectors, and dual-mass flywheel are all potential future costs worth pricing in. Estimated annual running cost is £1,800-£2,400, accounting for the higher-than-average mileage and the likelihood of wear-related repairs on a high-mileage executive car.

Start with a close look at the rear brake discs and pads, as advisories for both appeared in 2024 and again in 2026, indicating ongoing wear rather than a one-off replacement. Inspect the front suspension thoroughly, particularly the nearside front coil spring which was recorded as fractured at the August 2026 test, and check the offside for symmetry. The rear shock absorber fluid leak flagged as a serious failure in 2024 must be confirmed as professionally replaced, and the nearside front side repeater should be tested for correct operation. On the engine, the oil leak advisory from 2024 warrants a careful under-bonnet inspection and an oil level check, paying attention to the oil filter housing and valve cover gasket which are common N47 diesel leak points.

Beyond the MOT-specific items, check the condition of the dual-mass flywheel if any clutch slip or shudder is evident on the test drive, and listen for timing chain rattle on cold start which is a known weakness of the N47 engine. Verify the operation of all electrical features including the iDrive system, climate control, and any optional adaptive suspension, as repair costs on these systems can run into four figures. Finally, inspect the bodywork for corrosion around the wheel arches, under the boot seal, and along the sills, as 2010-era 5 Series examples in the UK can show rust in these areas.
