Transmission box number
There are two groups of numbers for identifying the gearbox. The first group is located on the top of the clutch housing. It contains the letters of the gearbox code (first 3 numbers or letters) and the date of manufacture. The second group is located on the side of the case and indicates the type of gearbox.

Model data sticker
Inside the trunk, on its lid, there is a sticker indicating the model code, chassis number, body type, paint number, engine and gearbox codes and a set of additional equipment.
Identification of body parts
The main body parts on all models from 1991 onwards are marked with the VIN number and the Audi emblem (4 rings). This is done to combat theft and the sale of the car in parts. All replacement genuine parts also have the Audi logo and a plate with the designation "R DOT" in the place of the VIN for this car.
