Should I check the MOT history before buying a 2004 BMW 525d 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 2004 BMW 525d 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 2004 BMW 525d 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 2004 BMW 525d SE reliable?

Based on MOT data from 128 vehicles, the 2004 BMW 525d SE has a first-time MOT pass rate of 69.1%, indicating average reliability for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2004 BMW 525d 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.

The 2004 BMW 525D SE is a significantly unreliable proposition—only 44.2% pass their MOT first time, compared with the UK average of 80%. The good news is that dangerous defects are absent from this cohort, so safety isn't the primary concern; rather, you're looking at persistent mechanical problems that require repeated repairs.

These cars are averaging 176,763 miles, which is genuinely high for a 20-year-old vehicle, and each one typically racks up just under one failure per test—suggesting wear and cumulative neglect rather than isolated issues. If you're considering one of these, budget heavily for immediate repairs and get a thorough pre-purchase inspection by a diesel specialist, because the pattern here points to expensive running costs.
