1. Windshield: The VIN number is usually etched in the lower-left corner of the windshield, visible from outside the car.
2. Driver's Side Door Frame: Open the driver's side door and look at the door pillar (the vertical metal frame between the door and the windshield). The VIN number should be stamped on a metal plate or sticker affixed to the door pillar.
3. Engine Compartment: In some Audi A4 models, the VIN number may also be found on a metal plate in the engine compartment, near the firewall (the wall separating the engine compartment from the passenger cabin).
4. Vehicle Documents: The VIN number is also included on the vehicle registration and insurance documents.
It's worth noting that the VIN number is a unique identifier for your car and is essential for various purposes such as registration, insurance, maintenance, and parts ordering. Make sure to keep a record of the VIN number in a safe place for future reference.
