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. On a Audi Q4 E-Tron S Line 40 bought as a 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.
