Vauxhall Astra Sxi Cdti 100 (2008)
2008 Vauxhall Astra Sxi Cdti 100
CarHunch analysed 131 real MOT records for the 2008 Vauxhall Astra Sxi Cdti 100. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2008 Astra diesel has a first-time pass rate of just 60.5%, significantly below the UK average of 80%, which signals a reliability concern for a 16-year-old car. On the positive side, dangerous defects are essentially absent from this cohort, suggesting serious safety issues are rare once you've found a sound example.
The median mileage of 128,176 miles is typical for an Astra of this age, and with an average of 1.03 failures per test, owners should expect regular repairs rather than a problem-free ownership experience. Before buying, have a pre-purchase inspection done by a diesel specialist—the pass rate tells you that time and money spent upfront will likely save you from inheriting someone else's deferred maintenance.
What to check before buying a 2008 Vauxhall Astra Sxi Cdti 100
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.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
