What is the method to unlock the Passat B5 audio system?
1 Answers
If you know the password, you can input it using the radio buttons 1, 2, 3, and 4, then press the power button and the fast-forward button to confirm. A beep sound will indicate successful unlocking. If you have the necessary equipment, you can directly decode it using a programmer. When manually entering the code, be careful not to press the wrong buttons or input incorrect codes. You are only allowed two incorrect attempts at a time. Exceeding this limit will permanently lock the system, requiring a 24-hour wait before retrying.
