Should I check the MOT history before buying a 2008 BMW 520d M Sport?

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 2008 BMW 520d M Sport?

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 2008 BMW 520d M Sport?

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 2008 BMW 520d M Sport reliable?

Based on MOT data from 330 vehicles, the 2008 BMW 520d M Sport has a first-time MOT pass rate of 79.5%, 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 2008 BMW 520d M Sport?

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

The 2008 BMW 520D M Sport is a serious reliability concern: just 17.8% of these diesels pass their MOT first time, compared to the UK average of 80%. With virtually no dangerous defects recorded, the issues aren't safety-critical, but the sheer failure rate suggests these cars need substantial work to get through testing.

At nearly 145,000 miles on average, these are high-mileage examples, yet they're still racking up 0.27 failures per vehicle on test—well above what you'd expect even for their age. If you're considering one, budget for pre-purchase inspection by a BMW specialist and expect repair costs to be significant before it becomes reliably roadworthy.

The 2008 BMW 520d M Sport passes its MOT first time at roughly the UK average rate (79.5%) — solid but worth checking this vehicle's history carefully.
