Vauxhall Insignia Exclusiv 158cdti (2011)
2011 Vauxhall Insignia Exclusiv 158cdti
CarHunch analysed 106 real MOT records for the 2011 Vauxhall Insignia Exclusiv 158cdti. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2011 Insignia 158 CDTi diesel struggles to match the UK average, with a first-time pass rate of just 71.6% against the 80% benchmark—a meaningful gap that suggests buyers should budget for pre-purchase inspection and some remedial work. The good news is that dangerous defects are absent from this cohort, so safety-critical failures aren't a pattern here.
At 110,400 miles median, these cars show typical wear for their age, and the 0.67 average failures per vehicle tells you to expect at least one fix when testing one. Before making an offer, get a full pre-purchase MOT history check and have a diesel specialist inspect the engine bay, as the pass-rate gap points to accumulating mechanical fatigue rather than isolated problems.
What to check before buying a 2011 Vauxhall Insignia Exclusiv 158cdti
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.
