2009 BMW 525

CarHunch analysed 1,516 real MOT records for the 2009 BMW 525. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2009 BMW 525 passes its MOT at 81.4%, fractionally above the UK average, but nearly half of these cars (45.6%) have recorded a dangerous defect at some point—a serious concern that should prompt thorough inspection of any used example you're considering. Diesel and petrol variants perform similarly, both hovering around 81% first-time pass rates.

These cars are averaging 95,890 miles at test, which is reasonable for their age, yet they rack up nearly 15 advisories per vehicle and almost 3 failures each—suggesting the 525 demands attentive maintenance to stay reliable. Before buying, get a pre-purchase inspection focused on suspension, cooling system, and electrical components, as these figures hint at where the age-related wear typically shows up.

What to check before buying a 2009 BMW 525

Practical pre-purchase checks for this age and model.

  • 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
  • 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
  • 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
  • ⚠️ 45.6% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
