BMW 525 (2011)

1,023 real MOT outcomes analysed • 83% first-time pass rate

2011 BMW 525

CarHunch analysed 1,023 real MOT records for the 2011 BMW 525. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2011 BMW 525 passes its MOT at 83%, marginally above the UK average of 80%, which suggests reasonable baseline reliability—but nearly half of these vehicles (45.2%) have recorded a dangerous defect at some point, a significant concern for any buyer. The diesel variant, which dominates this cohort at 1,016 of 1,023 vehicles, performs almost identically to the overall figure at 82.9%, so fuel type isn't a differentiator here.

These cars average 91,455 miles, which is reasonable for a thirteen-year-old model, yet they're racking up an average of 2.37 failures and 12.3 advisories per test—that's well above the routine wear-and-tear category. Before buying one, insist on a full service history and a pre-purchase inspection focused on suspension, cooling system, and electrical gremlins, which tend to drive repeat MOT issues on this generation.

What to check before buying a 2011 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.
  • ⚠️ 45.2% 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.
