BMW X1 (2018)
2018 BMW X1
CarHunch analysed 14,594 real MOT records for the 2018 BMW X1. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2018 BMW X1 is a strong MOT performer, with a 90.6% first-time pass rate that sits well above the UK average of 80%, and only 14.8% of vehicles ever recording a dangerous defect — a reasonable figure for a six-year-old premium compact SUV. Petrol and diesel variants perform nearly identically (91.3% and 90.0% respectively), so fuel type needn't sway your decision.
These X1s are running at sensible mileage for their age, with a median of 40,509 miles, and the low average failure rate of 0.63 per vehicle suggests most issues are caught early. However, the high advisory count of 4.5 per vehicle points to regular wear on consumables and minor systems — if you're buying one, budget for scheduled maintenance items like brakes and filters, and ask the seller for service records to confirm they've been properly looked after.
What to check before buying a 2018 BMW X1
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
