Audi E-Tron S Line 55 Quattro: MOT pass rate and reliability data

The Audi E-Tron S Line 55 Quattro passes its MOT first time more often than the average UK car, by 13.3 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 1,884 individual Audi E-Tron S Line 55 Quattro tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 90% first-time pass rate means roughly 10 in every 100 Audi E-Tron S Line 55 Quattros 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 E-Tron S Line 55 Quattro tested had covered 32,756 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 E-Tron S Line 55 Quattro sits 13.3 points above the national average, ranked 700 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.
