2017 BMW 2 Series 3.0L Petrol · K26 AAT

The 3.0-litre petrol engine in this 2 Series is likely to return fuel economy in the mid-20s to early-30s mpg depending on driving style, with combined figures typically around 32 mpg for the automatic M240i. Road tax for a 2017 3.0-litre petrol sits in a higher bracket than smaller engines, often £200-£300 per year, though exact figures depend on the specific variant. Insurance is likely to be in group 30-40 territory given the performance orientation, which can add significantly to annual outlay.

Typical maintenance for a 3.0-litre BMW straight-six includes higher-than-average parts costs for items such as brake discs, tyres, and engine consumables. Annual running costs including fuel, tax, insurance, and routine maintenance are realistically £2,200-£2,800 for this model. If a major service or timing chain work is due, budget an additional £500-£1,000.

Start with a close visual inspection of all four tyres for uneven wear, particularly on the inside edges, which can indicate alignment or suspension geometry issues. The 2024 MOT flagged nearside front tyre wear close to the legal limit and on the edge, while the 2022 failure was due to exposed ply or cords on two tyres, so a recurring pattern is worth investigating. Check both front road wheels for distortion, as noted in 2024, and run a finger along the rim edges to feel for any buckling.

Pay particular attention to the steering feel during a test drive, as play in the steering rack inner joint(s) was noted in October 2024. With the engine running, listen for any knocking or clunking from the front end over bumps, and check for uneven tyre wear that would confirm the steering issue has progressed. Beyond the MOT-flagged items, inspect the underside for any oil leaks from the engine or gearbox, condition of the brake discs and pads, and verify all warning lights clear on start-up. Finally, confirm the M240i-specific components (if applicable) such as the rear differential and adaptive suspension are functioning correctly, as these are costly to repair on the 3.0-litre variants.
