Hey I have a 2012 XK all of a sudden my audio sound went out my radio comes on just no sound at first I thought it was low battery so I bought a new one once I hooked it up the music came back on for two days then went back out!! So I don’t know if it’s the amplifier or what has anyone else had this problem or can guide me in the right direction please??

 

Your amp and subsequent speakers are fused in the Auxiliary junction box between the rear seats. Fuse 31= 30 amp. Does anything else bring sound? Have you tried a CD?

 

No nothing else is playing the radio or CD player or Sirius radio nothing or Bluetooth from phone

 

so fuse

 

I checked it looks like it’s fine is it a tool I can check it with

 

dumb questions. is 'Mute' selected? Is the rightful source selected? ... (sorry, its not specified and we need to get the obvious out of the way)

 

Are you talking about the phone call button if it’s another button for mute I need to look for it just bought the care a month ago

 

Yes he is. The mute button mutes audio as well as phone calls. Personally I thought it went off mute when you turn up the volume but I may be thinking of my wife's car so give it a try. It doesn't make sense that a battery swap would cause your problem.

Yes if you have an ohmmeter you can check a fuse. If you don't have one, just swap it out with a new one. They're cheap enough.
It's possible your amp has failed. If the basics are confirmed to be good, then the next step is get diagnostic trouble codes (DTC's) from the car.
For that you will need a code reader that reads all codes. Cost to you is about $70 but worth it when you're on a forum. We use codes to help.
There are several code readers out there. Just don't go cheap as some will only read engine codes and you will need body codes for this.

 

Thank you I just ordered it !!

 

While you are waiting.....locate the amp fuse as mentioned above and pull it. If its blown you can see it by holding it up to the light. Like Sean said, its a large 30amp fuse....so should be hard to miss.

Side note, On my old Range Rover, I had the sound cut out one day. All sources were dead. There were three different fuses that ran the infotainment system. I pulled them one by one, nothing. Then I pulled all three and let it do its thing. It worked.

 

Check fuse 21 as well, It controls the ICM, the integrated control panel and the steering wheel controls.

 

@lear60man , well done. Thats a well known work around for the ML63, too. Essentially it boils down to resetting the module to factory defaults.
I don’t quite understand it though. That is, Powering the car off and on does not have the same effect as pulling the fuses.

 

Thanks. The only thing that makes sense is that various infotainment systems have a back up source of power to retain radio presets/GPS waypoints etc. Pulling all the related fuses removes the other source of power and allows it to fully reset. Due to bad weather, I took my Range Rover to work yesterday. The sound quality is night and day between it and my 15 XK. Im warming up to the idea of a Tesla style head unit to finally get quality sound.

 

Would not a Hard Reset also do this?

 

yep

 

I checked all the fuses again an pulled them all to still no sound an fuses where not blown

 

Understood. We'll need to know the error codes your seeing then to be of more help.

 

I have had this happen on my 2010 XKR several times in my 8 year ownership as well as radio station presets don't appear on the screen, just blanks. Typically, either turning on and off the radio or restarting the car clears it up. Obviously, you've started your car many times since this started happening, so you must have a different issue.

 

I have had the same issue as Tberg describes and have applied the same fix(es) & they work for me.
