The numbers

What this means if you are buying one

A 88.3% first-time pass rate means roughly 12 in every 100 Audi Q4 E-Tron S Line 40s presented for MOT fail on the first attempt. That is better than average, so a well-kept example is a reasonably safe used buy. The average Audi Q4 E-Tron S Line 40 tested had covered 31,110 miles and was built around 2021.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Audi Q4 E-Tron S Line 40 sits 11.6 points above the national average, ranked 955 of 2,005 models. On one bought as repairable salvage, the mechanical side is less likely to spring surprises, so your repair estimate should hold up reasonably well.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.
