Vauxhall Astra Sri Nav Cdti S/s (2017)
2017 Vauxhall Astra Sri Nav Cdti S/s
CarHunch analysed 117 real MOT records for the 2017 Vauxhall Astra Sri Nav Cdti S/s. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2017 Astra diesel is a notably weak MOT performer, with a 63.1% first-time pass rate sitting 17 percentage points below the UK average of 80%. The good news is that dangerous defects are absent from this cohort, but the low pass rate signals systematic issues that buyers should take seriously.
At 73,347 miles median, these cars are mid-range for their age and mileage isn't the culprit here. The average 0.14 failures per vehicle suggests recurring niggles rather than isolated problem cars, pointing to common wear items or design issues typical of this generation—so budget for repairs before your test and have a pre-purchase inspection focus on suspension, brakes, and emissions-related components.
What to check before buying a 2017 Vauxhall Astra Sri Nav Cdti S/s
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.
