The 2021 Audi A3 Sport 40 TFSI E hybrid is a notably reliable performer, with an 89.9% first-time MOT pass rate that sits well above the 80% UK average—and only 10% of vehicles have ever recorded a dangerous defect, which is reassuringly low. This is a clean, modern hybrid powertrain with no significant fuel-type reliability splits to worry about.

The 1.8 advisories per car are mainly minor wear items rather than structural concerns, so if you're considering one, a pre-purchase inspection focused on the hybrid battery health and any electrics issues would be prudent.

What to check before buying a 2021 Audi A3 Sport 40 TFSI E S A

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.
