Should I check the MOT history before buying a 2012 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 2012 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 2012 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.

Based on MOT data from 1,085 vehicles, the 2012 BMW 520d M Sport Auto has a first-time MOT pass rate of 83.5%, 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 2012 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 2012 BMW 520D M Sport Auto is a serious reliability concern—just 31.5% pass first time, nearly half the UK average of 80%, and that applies across the diesel fleet with virtually no variation. The good news is that dangerous defects are not present in this cohort, but owners are still facing real problems at MOT time.

At 109,750 miles median, these cars are racking up genuine mileage for their age, and the 0.42 average failures per vehicle suggests consistent mechanical or emissions issues rather than one-off glitches. Before buying one of these, get a full pre-purchase inspection focused on the diesel engine and emissions system, because the MOT pattern shows you'll likely face repairs within the first year of ownership.

The 2012 BMW 520d M Sport Auto passes its MOT first time at roughly the UK average rate (83.5%) — solid but worth checking this vehicle's history carefully.
