W216 2008 CL500, no sound from Comand

Very hard for me to follow, the CD must have been open circuit on the optic ring.

They looped out the CD Changer its no longer in circuit everything else now works.

What a shame that an optic check was not done, that is so simple to do.

Well i was told by first garage they had tested the optic fibre from the head to the boot and they had a signal but the signal was not going from the boot back to the head so they said the amplifier was at fault.
Took that as the expert opinion had been told they knew their merc electrics guess they dont know CL electrics!!

That was sad, at least you have sound now as toy say but you could have done other things with that money

thats right Malcolm but on the bright side i have a spare amp or one that i can sell and lesson learned experts only for this car for repairs be cheaper in the long run and they checked it all out on the scan and no other problems all in fine health.
Thank you for your input and advice and commiserations good man

Sorry to open the thread again, I have a 2011 model with a similar problem. I have linked out the amp and then the tuner with no change.
The fault is no sound and no tuner display or cd display. It just says device unavailable.
Any help would be appreciated

Cheers John

I am pretty sure the fault is the amplifier, does anyone know the contact details in Sofia to send it to for repair please or is there anyone in the UK who is cheap enough?

Cheers John

John,your car please, is it a 221 or 216.

 

[John390]

Hi Malcolm, it is a W216 CL500 2011
Cheers John
ps If you now know what is wrong I could repair it myself!

Hello John, I found by lowering the amp and one finds no optic output in the optic socket, these thing do have a 12v start up as well. I search for ages for parts and gave up and sent it to Sofia.

Mine is all fine, they did a good job, sure £280 all in including postage that was £65, but they do come with a good guarantee.

 

[John390]

Thanks Malcolm, but This car has good fibre optic connections. It was plugged into star which diagnosed no communication with the amp. This points to a faulty amp.

Cheers John

Good luck with it, just shocking that Mercedes can take thousands on all this.

 

[John390]

Do you have the contact detail for Sofia please>

An update.
I sent the amp away to Sofia. They could not repair it. They did not charge other than the postage which was 92 eur!

The question I now have is, are all of this type of amp compatible as I have found it impossible to locate a second-hand unit with the same part number in the UK.

Any help would be appreciated.

Cheers John

This only seems to leave some later models,,,not easy but I will see, is yours a HK amp.

 

[John390]

The part number of my amp is:
A221 900 81 03
It says on the label, Harman/Becker.

Cheers John
