2022 BMW 330D M Sport PRO ED Mhev Auto 3.0L Electric diesel · MT22 VRP

The 3.0-litre B57 diesel in this specification typically returns 40-50 mpg on a long motorway run, with real-world mixed driving closer to 38-45 mpg. As a Euro 6 AP diesel registered after April 2017, this vehicle falls into a low road tax band, though the exact VED rate should be confirmed via the DVLA as it depends on the list price recorded at first registration. Insurance is likely to be in group 35-40 given the 330d power output and M Sport Pro specification, so premiums will sit firmly in the higher bracket.

Annual maintenance on a BMW 330d of this age typically runs higher than mainstream saloons — expect £400-£700 per year for routine servicing at a specialist or BMW dealer, plus potential additional costs for brake discs, tyres (typically £600-£900 a set for the M Sport Pro wheels) and AdBlue top-ups. Diesel-specific items such as DPF cleaning or replacement, and potential injector work, can push costs higher if neglected. Estimated annual running cost is £2,200-£2,800 including fuel, tax, insurance and routine maintenance.

Although no MOT defects have been recorded, the most common issues reported on the B57 diesel engine in the 3 Series are timing chain stretch, EGR cooler failures and swirl flap issues — none of which an MOT will always catch early. On a physical inspection, check for black smoke on start-up, any rattling from the timing chain area when cold, and ensure the DPF performs an active regeneration during a longer test drive. The MHEV 48V mild-hybrid system should be scanned for stored fault codes, as battery and belt-driven starter-generator issues have been noted on similar models.

Visually inspect the M Sport Pro body kit, the larger alloy wheels for kerbing damage, and check the operation of all iDrive infotainment functions including the parking sensors and reversing camera. Diesel-specific MOT failure categories to be aware of in older examples include emissions-related defects, so confirm there are no stored emissions or AdBlue fault codes. Verify that the auto box (ZF 8-speed) shifts smoothly through all gears, and check the condition of the rear diff mount, which can deteriorate on higher-mileage examples.
