Computed from DVSA MOT results, all of Great Britain, 2025. Nothing here is opinion.

Tyres, pads and stone chips say more about how the car was driven and maintained than about how it was built.
Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.
The wiring loom that runs into the glass tailgate flexes every time the boot opens and closes, and over years the insulation splits where it bends. Owners see a false 'boot open' warning, a dead number plate light, a reversing camera that cuts out, or a rear light that fails intermittently rather than staying off. It tends to show up from around 5 to 8 years old and is a fiddly rather than expensive fix once found, typically £100-300 in labour to trace and re-tape or replace the loom section. This lines up with the measured MOT data for this segment, where lights and electrics is the standout fault category; the loom crack looks like a real mechanical cause behind at least some of that pattern.
On the B47 diesel engine used in the X2 18d and 20d, the EGR cooler can develop an internal leak that lets coolant mix with soot in the exhaust gas recirculation system, which in rare cases has been linked to smouldering deposits near the intake manifold. BMW ran a safety recall covering B47-engined cars and extended the EGR cooler warranty to 15 years from first registration, so a car within that window should have been checked or replaced free of charge. Ask to see proof the recall work was done; if it wasn't, get it booked in before buying. Doesn't apply to petrol X2s.
The B46/B48 petrol engines use a plastic-impeller water pump and a plastic oil filter housing, both of which are known to crack or perish and weep coolant, sometimes as early as 30-40k miles and commonly by 60-80k. The giveaway is a faint sweet smell, a coolant top-up that keeps dropping, or a puddle under the passenger side of the engine bay. Parts and labour together usually run £300-600 depending on which component has gone; leave it too long and it risks overheating the engine. No BMW recall on this, but it is repeatedly reported by independent BMW specialists and parts suppliers.
The upper passenger-side hydraulic engine mount is a repeatedly reported early failure point, with owners noticing extra vibration at idle and a clunk on take-up of drive or when accelerating hard, typically from 50-80k miles. It's a known item to check on a test drive rather than a big-ticket disaster; replacement is usually a few hundred pounds. Reported on both petrol and diesel X1/X2 sister models, so it looks like a shared-platform part rather than an engine-specific one.
Cars with the 7-speed Steptronic dual-clutch auto can feel rough and hesitant pulling away from a stop or crawling in traffic, especially when the box is still cold, then smooth out once warm. It's the normal character of this type of gearbox rather than a fault in most cases, but owners do report the odd car with a persistent shudder around 1-2mph that needs a clutch adaptation reset at a dealer. Doesn't apply to manual X2s, which are rare in the UK but do exist on early cars.
Some specialists flag rattly wastegates and carbon build-up on the intake valves (a known trait of direct-injection engines) as a reason idle can get lumpy and economy can drop by around 80k miles miles on the B48 petrol. Owners disagree on how much this actually matters in practice; plenty of high-mileage cars run fine on standard servicing, and a walnut-blast declarbon isn't something every car needs. Worth asking about if buying an older, higher-mileage petrol, but not a reason to walk away on its own.
