Our Verdict
Overall the 2018 BMW X1 looks like a solid purchase, but prospective buyers should watch the tyre and brake wear noted in the MOT advisories.
When negotiating, use the tyre‑wear advisories (2024 off‑side front tyre and 2022 nearside front tyre) as leverage to request a price reduction or a fresh set of tyres. Verify that the brake discs have been inspected or replaced since the 2025 advisory about front disc wear. Request a full service history, paying particular attention to any diesel particulate filter (DPF) regeneration work, as diesel X1s can develop DPF issues if not regularly serviced.
Check that the vehicle has had regular oil changes with the correct specification for the 2.0‑litre diesel engine. Look for evidence of any major repairs or warranty work, especially around the suspension or electronic systems, which are common expense areas for premium compact SUVs. If the seller cannot provide a complete service record, consider a pre‑purchase inspection by a BMW‑qualified mechanic.
The 2.0‑litre diesel engine typically achieves around 45 mpg (combined), translating to roughly £950 in fuel costs for a typical 10,000‑mile annual mileage at current diesel prices. Road tax for a 2018 X1 diesel sits in the £150‑£200 band, while insurance groups are usually in the 20‑25 range, costing about £600‑£800 per year. Maintenance on a premium brand like BMW can run £500‑£700 annually, covering oil changes, brake pads, and routine servicing. Overall, expect an annual running cost in the region of £2,200‑£2,500.
Inspect the front brake discs closely, as the 2025 MOT advisory highlighted wear that could affect braking performance. Measure disc thickness and check for scoring or uneven wear. Also examine the front tyres for tread depth and any sidewall damage, given the advisories in 2022 and 2024 about tyres being close to the legal limit.
Review the condition of the diesel particulate filter and any related warning lights on the dashboard. A history of DPF regeneration or replacement would be a positive sign. Additionally, check the suspension components for any knocks or leaks, and verify that all electronic features (e.g., infotainment, parking sensors) operate correctly, as these systems can be costly to repair on a BMW.
The X1 has logged 40,071 miles over seven years, well below the UK average for its age, and has a clean MOT record with only advisory notices. Recent advisories point to front tyre wear and brake disc condition, which are typical wear items rather than mechanical failures. The diesel 2.0‑litre engine offers good fuel economy for long‑distance driving, while the silver finish remains popular and easy to maintain.
While specific aggregate data is unavailable, the BMW X1 is generally regarded as a reliable compact SUV, though diesel variants can be prone to DPF issues if not regularly maintained.
