Should I check the MOT history before buying a 2015 BMW 520d SE Auto?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2015 BMW 520d SE Auto?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2015 BMW 520d SE Auto?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Is the 2015 BMW 520d SE Auto reliable?

Based on MOT data from 368 vehicles, the 2015 BMW 520d SE Auto has a first-time MOT pass rate of 93.3%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2015 BMW 520d SE Auto?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

Moderate sample. 368 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This 2015 BMW 520D is a significant reliability concern: only 34% pass their MOT first time versus the UK average of 80%, putting this model in the bottom tier for its age. The good news is that dangerous defects are virtually non-existent at 0%, so while these cars fail, they're failing on fixable issues rather than safety-critical ones.

At nearly 100,000 miles on average, these are well-used executive saloons, yet they're averaging just 0.13 failures per vehicle—suggesting most cars pass second or third time with minor corrections. Before buying, budget for pre-purchase inspection by a BMW specialist and expect some teething problems in the first year of ownership, but don't assume the engine or gearbox are inherently weak based on MOT history alone.

The 2015 BMW 520d SE Auto passes its MOT first time more often than most UK vehicles (93.3% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
