2022 BMW X6 M Competition Auto 4.4L Petrol · PK10 LLY

Fuel economy for the X6 M Competition is officially rated at around 21-22 mpg combined, though real-world figures typically drop to 15-18 mpg. With a 4,395cc engine producing over 600 bhp, annual fuel costs for a typical driver covering 8,000 miles will likely be in the region of £3,500-£4,500 at current UK petrol prices. Insurance is a major consideration — this model sits in one of the highest insurance groups (group 50), and premiums commonly range from £2,500-£4,000 per year depending on the driver's profile and postcode.

Road tax for a 2022 Euro 6 AP petrol vehicle of this engine size falls into the higher bands, costing approximately £600-£650 per year after the first-year supplement. Servicing at a BMW main dealer is expensive, with annual M-schedule services typically ranging from £600 to over £1,200 depending on whether brake fluid, spark plugs, and oil changes are all due. Tyres are a significant cost: the X6 M Competition runs staggered 21/22-inch fitments with run-flat tyres, and a full set can cost £1,500-£2,500. Annual running costs realistically total £7,000-£9,000 for a moderate-mileage owner.

Although both MOT tests passed with no defects recorded, the model's aggregate failure data highlights tyres, headlamps, and windscreen wipers as the top failure reasons across 351 vehicles analysed. On inspection, carefully check all four tyres for uneven wear — inner shoulder wear on the rears is particularly common on this rear-biased AWD model. Run the headlights through all functions (dipped, main beam, indicators, DRLs) and inspect for condensation or LED module faults, as headlamp issues are a noted weak point for this generation.

Beyond the MOT-relevant items, this M Competition variant warrants scrutiny of the S63 4.4-litre twin-turbo V8 for any oil leaks from the valve cover gaskets, oil filter housing, and turbo oil feed lines. Check the eight-speed M Steptronic automatic transmission for smooth shifts and any hesitation. Inspect the undertrays and front splitter for kerbing damage (common on large SUVs with low front ends), and examine the massive M-brake callipers for corrosion and pad wear — replacement brake discs and pads can exceed £2,000 at a specialist.

Finally, verify all driver-assistance systems work correctly: adaptive cruise, lane-keep assist, 360-degree cameras, and parking sensors. Run the iDrive system through all menus to check for warning messages, and confirm the digital instrument cluster displays no faults. A diagnostic scan at a BMW specialist is recommended to check for any stored fault codes that wouldn't show on a standard MOT.
