Citroen C4 Sx HDI (2007)
2007 Citroen C4 Sx HDI
CarHunch analysed 125 real MOT records for the 2007 Citroen C4 Sx HDI. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2007 Citroën C4 SX HDi has a first-time MOT pass rate of 63.2%, noticeably below the UK average of 80%, which signals reliability concerns for this age and model. The good news is that dangerous defects are absent from this cohort, so safety isn't the problem—the failures are mainly minor mechanical or wear items.
At 135,852 miles median, these cars have racked up typical mileage for their age, yet they're averaging 0.95 failures per test, suggesting the diesel engine and running gear accumulate issues as they age. If you're considering one, budget for repairs before purchase and get a pre-buy inspection focused on the drivetrain and emissions systems, since that's where the problems cluster.
What to check before buying a 2007 Citroen C4 Sx HDI
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.
