Hi
So, if you follow my channel for like, an eternity... lol... you have seen this car... was a long time ago, but is now back with new problems, and also to finish what the owner decided not to have done at the time...
I am starting the video by explaining an issue that for some weird reason I decided not to record, that said, was an interesting problem that came with a lot of work!
After that, the issue with the audio system...
The car had no sound, no radio stations plus some other issues... all because of 1 module...
Follow me on this video to find out what was the problem and how to resolve it.
Link to the old video on this car, be kind, was recorded quite long time ago... :-) :
• Mercedes S-Class W221 ...
Link to the next video on this car, engine and glow plugs light on:
• Mercedes S Class W221 ...
Hope you enjoy the video.
Any questions or comments put them below.
Like always, thank you for watching!

Well done yet again. Why people buy an expensive car, but are not willing to spend the money to maintain it is beyond me. I noticed the car has come to you with the standard amount of fuel. 👍

☺️ The standard indeed! 😅 👍👍👍

The joy of Mercedes sound systems. Have lots of experience with these and they are a pain. The MOST bus goes through head unit, phone, CD, TV tuner, tuner/ Amp, digital radio unit. Any failure will stop the sound. Most failures on the S-Class sound system are related to water in the boot. When valeters clean the wheel arch with a pressure washer the water sprays in through the side boot airvent (to allow boot to close) and ends up in the electronics. Some you can fix and some are so badly corroded and require replacement. Same issues also affect CL's... And others

Thank you for this post.. Same thing in going through right now.. I have a 2011 Mercedes benz s550 4matic water got in. I replaced the satellite module but I still got no sound . Car came with bang & olfusen system .so in the back left hand side is 2 amps and the satellite tuner can you help

@burningflare8977 3 месяца назад

@STILLKINGSTON73 From all that I have seen, the no sound condition is typically caused from a dead amp. One thing you can try is by inserting a fiber loop into the voice control module section and seeing if that does the trick. If this doesn't work than most likely you have a dead amp.

@mikesabin8568 10 месяцев назад

You need a loop tool to loop out the modules on the fibre optic. If you loop out the bad module, radio comes to life

@LMAutoRepairs 10 месяцев назад

Yes... I have that loop... In this case was not necessary... 👍👍👍

Excellent repair. Just about every motor like this I get in the owner is as tight as a ducks @rse. The quality of the supplied battery was a give away. One question, when the TV is coded out how does the MOST ring still work without a loop reflector being fitted to the TV module plug? Or did you take the fibre optic cables from the TV plug and plug them into the Bluetooth and Tuner cables to complete the loop so to speak.

@LMAutoRepairs 10 месяцев назад

The latest... I removed the small loop from the Bluetooth module and the TV tuner... Otherwise yes, would need a loop on that plug... 👍👍👍

@MrByootox 9 месяцев назад

Great video Loius! But what an absolute dog of a car 🙈 Great tip about the MOST as well having the arrows👌 I had something similar in my E61 with the DAB module being removed previous to my ownership. Wish I'd seen this video a few years back 😂👍 I find the optical loop plugs are a good help for trying a quick fix or temp repair in these MOST systems. These electric seats are a nightmare when they stop working like that 🙄🙄

The radio in my GL 450 comes and goes. Sometimes it works for days with no problem. Then some days it goes in and out. The radio is still working but no sound is coming out. The phone can call and answer but I can’t hear anything because there is no sound. It happens randomly. Then it May suddenly have sound. So annoying.

@LMAutoRepairs 3 месяца назад

Scan the car, and see if there is any faults that can point into any direction... 👍👍👍

@yakuzahi 3 месяца назад

Hello. I have a friend with 08 S550. The Bluetooth stopped working for a while now. The dealer asked for $3000 to fix it. Last week I told him to buy a 30 pin dongle Bluetooth adapter that he connected to the 30 pin iPod cable in the glove box. This also didn't work. But now, after he played with the AUX feature, the FM, AM show nothing, And there's no sound like in your video. Do you think that it's going to be a good idea by changing the Bluetooth radio computer, and take the chance? Thank you.

@LMAutoRepairs 3 месяца назад

Hi Difficult to tell without a few checks... As per the video, the tuner is also the amplifier module, so makes sense to loose sound and the tuner at the same time... You need to check if there is no blown fuses etc... before proceed any further... But there is a good possibility that the tuner/amplifier module has been messed up... 😬 👍👍👍

Hello i need help.. I have a 2011 mercedes benz s550 4matic.. Water got in my trunk and diagnosis show my satelite radio tuner was the problem.. I sent itboff to get repaired and when i plugged it back in i still getbno sound and that part was repair and seem to be working.. Im now only getting codes 94D5 and 94D2.. Can someone help me please.. Im not getting no sound at all..y navigarion still work.. My phone still connect but i cannot use the steering wheel buttons i also can connect bluetooth but still cant play anything

@LMAutoRepairs 3 месяца назад

Have you watched this video?

@STILLKINGSTON73 3 месяца назад

Yes I did sir..many times.. But I don't see anything you refer to as the "sound processor.." In video you said you still get no sound.. My satellite tuner was already repaired .. I plugged it in and still no sound .. When sent my satellite tuner for repair I also sent my amp also . Mercedes repair shop said my amp was good.. The person before me who own this car, when buying brand new from the dealer they opted for the bang & olufsen sound system.. Not the Kardon.. So in my trunk on the left side is satellite tuner and 2 bang olufsen amp.. A big one with 1 big plug going to it and another with bang fiber optic loop.. In my car there is no voice command module on the left side or the right side of the trunk. In my car the voice control module is sitting under the dynamic seat pump .My voice control module has no fiber optic going to it so I cannot bypass it to test.. Thank you for replying toe and the community, but I don't know what else do.. Also when scanner if hooked up I get no codes relating to them..

@LMAutoRepairs 3 месяца назад

@STILLKINGSTON73 🤔 29:30 Not sure which video you have been watching... Now, the sound processor or amp... same thing... The main thing is, if you can communicate with the amp, the most bus is ok, and the speakers are connected, then I would say you have a dead amp...

Hello, My issue as it stands: - All power + grounds are working going into all units - Red light inside the comand unit glows - Amp is new just as a precaution - When a scanner is plugged in, the comand and other audio related equipment do not show up. They show as blank as if theyre not equipped. - I have checked all fuses to be good with power going across any related to the comand audio system. - There is no display of anythont on the screen. It remains black but can still tilt. Any idea of where to start?

@LMAutoRepairs 4 месяца назад

Hi The command should boot regardless of any of the other components related to to working or not... Have you pulled the command out of the center console? It looks like the command is not booting up...

@burningflare8977 4 месяца назад

@@LMAutoRepairs by remove the comand, are you referencing the unit with the cd changer? I have removed it and checked it but did not see any corrosion within and I removed all the iPod related cables to narrow down the issue. I checked all the pins and all are good.

I am working towards getting a Xentry Compatible Scanner.

@LMAutoRepairs 4 месяца назад

Right... it seems like there is an issue with the command, but you have other systems not communicating that might or might not be related... You need to understand first what is common to all of those units, and figure out why are they not communicating... Focus on the central gateway (CGW), as that can impact multiple systems... I wouldn't buy any parts just yet...
