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

Based on MOT data from 104 vehicles, the 2006 BMW 520d M Sport Auto has a first-time MOT pass rate of 71.5%, 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 M Sport 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 M Sport is a serious reliability concern—only 9.6% pass their MOT first time, roughly one-tenth of the UK average of 80%, and there are no recorded dangerous defects to worry about, but the sheer scale of failure is alarming. At nearly 192,000 miles on average, these cars are well-worn, yet even accounting for age and mileage, a 90% failure rate on first test is far worse than comparable vehicles and suggests systemic build or maintenance issues with this particular generation. The low advisory count (essentially zero per car) combined with high failure numbers means problems tend to be serious rather than minor—typical failures likely involve emissions, suspension, or brake systems rather than cosmetic niggles. If you're considering this model, factor in significant MOT repair costs and budget for a pre-purchase inspection by a diesel specialist; the numbers don't support buying one hoping to get lucky.
