This loss of power could be caused by a disconnected battery, faulty battery or simply a battery with a low charge. Regardless of the reason for loss of power, a security code is required to restore the radio to its normal operating condition. If youve lost your radio code, youll need to gather some information and visit your local Audi dealership in order to obtain a new radio code.
