2017 Land Rover Discovery Hse Td6 Auto

CarHunch analysed 189 real MOT records for the 2017 Land Rover Discovery Hse Td6 Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2017 Discovery HSE TD6 diesel passes MOT first time only 66% of the time, well below the UK average of 80%, which means roughly one in three fail their initial test—a reliability concern that buyers should take seriously. The good news is that dangerous defects are virtually non-existent in this cohort, and there are almost no advisory items flagged, so when failures do occur they're typically fixable rather than structural problems.

With a median mileage of 71,125 miles for a seven-year-old vehicle, these Discoverys are running roughly average wear for age, yet they're still generating 0.25 failures per vehicle on average. Before purchasing, have a pre-buy inspection focus on common diesel issues—suspension, brakes, and emissions components—since the MOT pass rate suggests these areas are where this model struggles.

What to check before buying a 2017 Land Rover Discovery Hse Td6 Auto

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.
