What this means if you are buying a 1998 A4
The 1998 is a weaker year for this model, passing 3.7 points less often than the Audi A4 average. Some of that is simply age, so compare it against the 1998 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 28-year-old car fails on
A 1998 car is 28 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 very high mileage. Clutches, dual-mass flywheels and head gaskets have usually been through at least one repair by this point, so ask for evidence rather than assume the car is original everywhere. On a 1998 Audi A4 the average at test was 153,346 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 2020 at 90%, and the weakest in our data is 2002 at 65.3%. That 24.7 point spread across the model's life is why comparing a 1998 car against a newer one tells you very little.
