CarHunch analysed 207 real MOT records for the 2021 Citroen Relay 35 L3 Bluehdi S/s. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2021 Citroën Relay 35 L3 BlueHDi matches the UK average with an 80.2% first-time pass rate, and dangerous defects are relatively rare at 13%, making this a reasonably safe bet for a commercial van of this age and size. These are proper work vehicles with modest mileage for their age (average 59,443 miles), which bodes well for durability in the field.

Most owners can expect to fix less than one fault per MOT cycle (0.61 failures), but advisories are common at 2.2 per vehicle—mainly wear items and non-urgent maintenance that come with a working van. Before buying, get a pre-purchase inspection focused on suspension and brake wear, since these accumulated advisories suggest the vans are being put to proper use rather than sitting idle.

What to check before buying a 2021 Citroen Relay 35 L3 Bluehdi 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.
