Should I check the MOT history before buying a 2006 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 2006 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 2006 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 2006 BMW 520d SE Auto reliable?

Based on MOT data from 210 vehicles, the 2006 BMW 520d SE Auto has a first-time MOT pass rate of 72%, 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 2006 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.

This 2006 BMW 520D is a serious reliability gamble: only 16.1% pass the MOT first time, less than a fifth of the UK average of 80%. At nearly 150,000 miles typical mileage, these cars are carrying genuine wear, but the real issue is that nearly 84% of them fail their MOT, suggesting systematic problems rather than just age-related deterioration.

The average of 0.43 failures per vehicle and complete absence of dangerous defects means the issues are fixable rather than unsafe, but the sheer failure rate hints at expensive repair bills—likely suspension, emissions, or engine components common to higher-mileage diesels. If you're considering one, budget for an immediate pre-purchase inspection by a BMW specialist and expect to factor several hundred pounds into your costs within the first year.
