Radio stopped working, need to replace fuse but owners manual is missing. Need to know which fuse is radio fuse.

Most likely a fuse. If your fuse box is labeled it will say radio under the fuse. If its not check your owners manual for location of fuse box and radio fuse.

You need the radio security code.

A good solution for this would be to get the Haynes repair manual on your vehicle. Since your owners manual is now missing the Haynes Manual can replace that and provide the information that you normally would get from the owners manual.

There's a dedicated fuse for radio. But most newer cars if you take out battery radio goes into "enter code" mode (security feature). You have to know special code to your specific radio. Info doesn't usually make it to second owners.

The location for the circuit breaker is in the fuse box under your hood number 601. Its a 30a CB.

i) fuse box for the audi A6 is most probably on the right side close to the driver;s seat by the steering wheel.  The driver door must be open to access the fuse box.  Please check owner's manual. ii) in the 2002 Audi A6 it is fuse #37.  Please check owner's manual. iii) remove the fuse for the radio then replace fuse. iv) start the engine v) the radio most probably will reset it self but you should not have to enter the security access code for the radio. let me know how the works. thanks

in the owners manual.

number 32 is the front cigarette lighter fuse 2 and 27 for the audio unit which i presume means radio
these are in the fuse panel under the dash on the drivers side

you should refer to your owners manual for the fuse size. if you are only missing 1 fuse and every thing else works ,Then my guess would be that is your reason for a non working radio. As well the fuse may have been removed due to a ground in the wiring.

Please check your owners manual for the location of the 10 amp fuse for the radio. On some models you have to reset the security feature on the radio/CD player for it to work.

The info below has been stated to work on a no go radio. I have not confirmed this procedure.

Remove the lower fuse box cover, with the power off, removed the 10 Amp fuse for the "Radio." the fuse may be good. Fuses are diagrammed in the owner's manual. With the fuse removed, start the car, turn the car off, replace the fuse and turn the key to "ACC" to see if the radio was "Reset."

Would the alarm cause the radio to malfunction? If your Anti Theft lock was activated check your owners manual under radio and check for a 4 number password. Sometimes it is taped to the upper part of the glove box. If you do not have the CODE you will need to take the vehicle to a dealership or a repair center. They use your vehicles vin number get the code.
