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

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?

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?

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 reliable?

Based on MOT data from 415 vehicles, the 2006 BMW 520d SE has a first-time MOT pass rate of 74.6%, 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?

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

The 2006 BMW 520D SE is in serious trouble on the MOT bench: just 28.1% pass first time versus the UK average of 80%, making it one of the most unreliable vehicles of its age. The near-zero dangerous defect rate is the only bright spot, but that's cold comfort when nearly three-quarters of these cars fail their test.

At 165,000 miles average, these diesels are well-worn and showing it—the 0.64 failures per vehicle suggests systematic wear rather than isolated problems, typical of high-mileage German saloons where repair costs quickly spiral. If you're considering one, budget for immediate attention to whatever caused the MOT failure, and seriously factor in whether the purchase price plus likely repairs makes economic sense.

The 2006 BMW 520d SE has a below-average first-time pass rate (74.6% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.
