CarHunch analysed 113 real MOT records for the 2020 Audi A3 S Line Ed 1 35 TFSI MHEV SA. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2020 Audi A3 is significantly more reliable than the average UK car, with a 91.9% first-time pass rate against the 80% national average—a genuinely strong result that suggests buyers can expect fewer unexpected repair bills. Only 10.6% of these cars have ever recorded a dangerous defect, which is reassuringly low and well below concerning territory.

When you're browsing examples, check the full MOT history for any advisories around brake wear or suspension—the most common culprits—but this model should give you solid ownership without constant trips to the garage.

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.
