Should I check the MOT history before buying a 2012 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 2012 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 2012 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 2012 BMW 520d SE Auto reliable?

Based on MOT data from 422 vehicles, the 2012 BMW 520d SE Auto has a first-time MOT pass rate of 87.4%, 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 2012 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. 422 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This 2012 BMW 520D SE AUTO has a first-time MOT pass rate of just 30.7%, less than half the UK average of 80%, which is a serious red flag for reliability. The good news is that dangerous defects are virtually non-existent at 0%, so safety failures aren't the issue—instead, owners are dealing with repeated minor mechanical problems that require fixes between tests.

At nearly 110,000 miles, these cars are running hard but the failure pattern suggests cumulative wear on BMW's complex systems rather than catastrophic defects. With 0.34 average failures per vehicle and no advisories recorded, the picture is of a diesel that runs but needs constant attention; any buyer should budget for regular trips to a specialist and get a thorough pre-purchase inspection from someone who knows German engines.

The 2012 BMW 520d SE Auto passes its MOT first time more often than most UK vehicles (87.4% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
