What is the Audi PIN code?

[NoraDella]

Audi's vehicle PIN code is either 0000 or 1234. The vehicle PIN code is provided to the owner by the 4S dealership when delivering the new car, in the form of a password letter, which is about the size of a bank card. If the owner needs to check their vehicle's PIN code, they can open this password letter to view it. If the 4S dealership does not hand over the PIN code password letter when delivering the new car, it is likely tucked inside the vehicle's user manual. If the owner loses the password letter and cannot find it, they can take the vehicle's registration certificate to a 4S dealership or authorized dealer. They will read the anti-theft device's identification code from the vehicle's control unit and then apply to query the PIN code. The car manufacturer will search the database and send the PIN code to the 4S dealership or dealer. The main purpose of the vehicle PIN code is for situations such as lost keys, damaged anti-theft torque converters, clearing fault codes, key matching, or damaged anti-theft ECU assemblies, which require re-matching the engine's electronic system. The owner can provide the PIN code to the repair technician, who will then use it to perform the necessary repairs to ensure the vehicle's security.
