What this means if you are buying a 1999 Tt

The 1999 is a weaker year for this model, passing 16.9 points less often than the Audi Tt average. Some of that is simply age, so compare it against the 1999 figure for all cars above rather than against newer examples. Check the exact car with the free MOT history checker before you buy, and run its VIN and mileage through our free VIN decoder and clocking check.

What a 27-year-old car fails on

A 1999 car is 27 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:

  • Lights and electrical: 10.36% of all cars tested
  • Suspension: 8.65% of all cars tested
  • Tyres: 6.23% of all cars tested
  • Brakes: 6.1% of all cars tested
  • Visibility: wipers, washers, glass: 4.65% of all cars tested
  • Body, chassis and structure: 3.18% of all cars tested

That is high mileage, so timing belts, clutches, suspension bushes and corrosion are the items worth budgeting for rather than the MOT itself. On a 1999 Audi Tt the average at test was 123,049 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.

The strongest year for this model is 2019 at 92.2%, and the weakest in our data is 1999 at 62.4%. That 29.8 point spread across the model's life is why comparing a 1999 car against a newer one tells you very little.
