Audi Tt: MOT pass rate and reliability data

The Audi Tt passes its MOT first time more often than the average UK car, by 2.1 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 113,830 individual Audi Tt tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 78.8% first-time pass rate means roughly 21 in every 100 Audi Tts 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 Tt tested had covered 78,642 miles and was built around 2011.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Audi Tt sits 2.1 points above the national average, ranked 1,485 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.

Looking at a specific Audi Tt rather than the model in general? The free check covers its MOT and mileage history, and the full HPI report confirms the insurance write-off category, outstanding finance and whether it is recorded stolen, from licensed data for 5 credits. Already own one that has been damaged? Work out whether fixing it beats selling it with the repair or scrap calculator, and see the median recorded closing bid for a damaged Audi Tt: £700 at UK salvage auction, from 20 ended listings, not independently confirmed sales.
