S500 '06 W221 (OE A 0031538328)

Gretings MB owners..

I have a S500 vw 2006 W221 (OE A 0031538328) and the problem has become Radio and CD "blackout" (No sound, no channels and the LEDs on the CD drives are all "red") The phone works with signal on but sounds off.

How it happens
In the morning usually when you start everything works (nowadays it may not be the case anymore) but when you make several short stops in the city it usually goes dark after 2-3 re-starts .. Before it worked for several weeks or even a month for one period but now it goes constantly "off".

I used MB official dealer and run tester work there, it gave "under-voltage" (Said the man from behind the counter) and the rear end battery was replaced but worked for 1 week ... problem started again.

Can anyone say by own experience or have good network from where to ask which part/component/device/rear end box/etc. could be the root cause for problem and how it could be eliminated so all would work again? (I need my radio :roll: If there is a "wizard" on the Turku-Pori axis who can help, I would be happy to receive information?)

I read the comments from this MB pages and there was mentioned in many that the Pre-Fuse box was the issue, so:
1. What box in question?
2. Where is it located? (Font engine area, trunk or inside car?)
3. Where can I order new part if found faulty?
4. Does anyone know the price range of this or needed part/component?
5. Can I change myself? Or do I need dealer/expert for some reason?

Pictures below how the Radio panel and CD unit looks like when problem occur:

Hi,

As far as I know. Usually MB has fuse box on passenger side footwell. Have you checked that place ?

If it is only fuse some local autopart seller should have.

I think we need to get some more information from MB service manual, how to fix that thing.

Hi,
Thanks for response, I have contacted dealer or let´s say a specialist now, taking car there next week let´s see what they can do? BTW do you know what might be Manufacturer Warranty period/time for S500 W221 Front Windshield Glass? It´s OEM part and installed by local MB authorized dealer April 2020 so only 1.5 years old and have started to crack (Inside window/double glass to my understanding), of course there are differences between countries and this is Finland but glass manufacturer should be global warranty? No stone or other have hit window...
