2014 Mitsubishi ASX 2.3L Diesel · RE14 BUA

The 2.3 L diesel engine in the ASX typically achieves around 45 mpg (imperial), translating to roughly £850‑£950 per year on fuel assuming 10,000 miles driven annually and current diesel prices. Road tax for a 2014 diesel of this size is likely in the £150‑£200 band, and the insurance group sits around 20‑25, meaning average insurance premiums of £600‑£750 per year for a standard driver.

Maintenance for a diesel SUV of this age generally includes regular oil changes, timing belt checks (if applicable), and occasional injector servicing. Given the recent brake pad wear, budgeting an extra £200‑£300 for brake component replacement is prudent. Overall, a realistic annual running cost estimate sits between £1,300 and £1,500, covering fuel, tax, insurance, and routine maintenance.

Start with a thorough brake inspection. The MOT record shows a dangerous rear‑brake‑pad failure (less than 1.5 mm) in July 2025 and thin front pads noted the same year. Examine both pads and discs for uneven wear, scoring, or corrosion, and confirm whether any parts have been replaced since the last MOT.

Next, inspect all four tyres for tread depth, sidewall condition, and any signs of damage. The MOT history repeatedly flagged front tyres worn close to the legal limit and a dangerous front tyre issue in 2018. Look for uneven wear that could indicate alignment problems, and ensure the tyres meet the minimum legal tread depth of 1.6 mm.

Finally, review the overall condition of the suspension and steering components. Repeated tyre wear advisories can sometimes stem from worn bushings or misalignment. A test drive should reveal any pulling, vibration, or unusual noises, which may point to suspension wear that could require costly repairs.
