1999 Skoda Octavia Glx TDI

CarHunch analysed 133 real MOT records for the 1999 Skoda Octavia Glx TDI. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 1999 Skoda Octavia GLX TDI is a serious reliability concern, with only 18.3% of tested vehicles passing their MOT first time compared to the UK average of 80%—that's a staggering 4-to-1 failure rate. Dangerous defects are rare at 4.5%, but the sheer volume of failures means you're looking at a car that will need real money spent on repairs.

At 134,840 miles on average, these Octavias are well-used and showing it: they rack up 0.44 failures and 0.7 advisories per MOT on average, with suspension, emissions, and structural problems being the norm rather than the exception. Before buying one, have a pre-purchase inspection by a diesel specialist—these cars can be cheap to acquire, but that 81.7% failure rate tells you exactly why.

What to check before buying a 1999 Skoda Octavia Glx TDI

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.
