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

Based on MOT data from 316 vehicles, the 2008 BMW 520d M Sport Auto has a first-time MOT pass rate of 76.5%, 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 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. 316 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This 2008 BMW 520D M Sport is a serious reliability risk: only 12.3% pass their MOT first time, compared to the UK average of 80%, and the diesel engines show no meaningful difference at 11.9%. No vehicles in this cohort recorded dangerous defects, which is the only bright spot, but the overwhelming failure rate suggests systemic problems with the model.

At nearly 146,000 miles median, these cars have travelled hard, yet they're still averaging 0.2 failures per test—meaning most don't fail catastrophically, just repeatedly. The low CarHunch score of 40 reflects a car that needs constant attention; if you're considering one, budget for regular specialist repairs and always get a pre-purchase inspection from a BMW-trained mechanic, ideally with a full service history to prove maintenance hasn't been skipped.

The 2008 BMW 520d M Sport Auto passes its MOT first time at roughly the UK average rate (76.5%) — solid but worth checking this vehicle's history carefully.
