My audio started cutting out and crackling a couple weeks ago. I disconnected the amp and cleaned all the connections and now it works perfect. Hasn't crackled since.
It is a bad Sat Radio Module. The fiber optic audio setup is used to take advantage of its advantages like better sound and fast speed for data, but bmw used it only for the audio and some audio/Navi information. It is one loop from start to finish. A module is placed INLINE with the loop, and therefore breaks the loop and so the output is fed back out to the fiber again thru the modules output side. So if you just unplugged the Sat radio module, you would be breaking the loop. (Which is what the bad module does when normally plugged in to cause your issue). So you.must use this piece to loop the input back out to the output so it can make its way back to the main Audio Head Unit (idrive & non idrive). The HU is the start and the end of the "circular loop" around the car. The loop bypass its fiber optic connection to the defective Sat Module and fixes your issues bc now the Sat Radio module is not in the fiber loop anymore. You also will not be able to listen to Sat Radio anymore, if you did. This fix can also be done the oem way as well plus its free. It is alittle more time involved and slightly complicated, but it requires no extra parts and there are plenty of DIYs dealing with the fiber loop distribution block or sometimes called fiber add-on point. You just need to take DS rear side panel, right by where your left shoulder would be if you were sitting in the back DS seat, you will find the fiber ring distribution block. What you would do is take the Sat radio out of the fiber loop by unplugging the fiber wire running to it for input and re routing directly the output. The fiber optic cables plug in to the block. There's pics and diy's online. For example if you have an older idrive and you are upgrading to the newer cic, and you have 2 modules in the trunk like in the video, one must be removed. The cic uses one module for usb/bt/aux/internet/etc, while the CCC would require 2 modules(TCU & MULF2). So therefore you would get to behind the seat side cushion and rearrange the fiber lines properly. The black shielding around the fiber indicates one side of the loop and the bare green fiber optic cable represents the other side of the loop. Good video I'm sure this will help a lot.of people with the same problems. The Sat module is a common part to go bad and is 1k$+ new and pricey used. Most of the time water in the trunk is to blame, but not the sole reason.
Any chance you can make a video showing us exactly where to plug this thing in at? I bought the one in the link, but not sure which cable to pull and plug this in at. We have the same car, it would be exact for me.
I had the problem on my X1 F48 2017 model. Assume it’s software have bugs. Tested to call SOS after shows SOS system failure message, get through perfectly, which proves the system NOT failure. Used voice control coincidentally last week, the fault message disappeared dramatically, and didn’t back till today. I rarely use voice control before, have tried to disconnect blue tooth device and reconnect from other youtube video, didn’t work well. Can’t say it’s the solution, but cost nothing and worth a try.
@@XllllllllX- I jus tried to look at the audio module... I think the model is too old since it is a 1995 740i. I will have to look at the rest of the wires another time and I will update you
@@rjaybruhh Yea I first I was trying to plug the loop into like the amp but than my dumbass realize that it was another module nd once I put it to that one it worked
Hi, I have inserted that in my bmw but the light still doesn't come on, I don't know if it's the product that came wrong or if it's something else besides.
My GOD this just happened to me last week. I knew it wouldn’t call, so I pressed the SOS button. It’called and locked everything out. Then I canceled the call, and audio and Bluetooth came back. This is just crazy. I’m going to bypass. Thank you for the video.
Hi! Sorry to revive this subject. I have a very similar problem, only my audio system does work while reversing or opening the doors. Do you think this bypass fix would work? Thanks!
I own a 2017 bmw 330i Xdrive. My sound and chimes all work on my car but sometimes the SOS error pops up and the goes away. It can be there for a few mins then it goes away. It can go days to weeks and then pops up. Any suggestions on how to fix And remove this error?
Hey man so my car I have a sub and amp hooked up but the sound all works but there’s no base everything works I have power to everything do you know what the issue is I had the sos light to line yours
Recently bought an 08 528i. No volume from radio at all, aux & CD are also greyed out on Idrive, tried the loop bypass but nothing changed at all. Any other suggestions?
My SoS call failure comes up and then my microphone won't work, so others can't hear me if on call or if I try to use voice commands. Do you think this would help? Thanks
Nice video, I got the exact same problem on my 330 E91 2008. I have to try it out, but I'm convinced this will solve my problem too. Thanks again for the video 🙂
@@IkeLuvNY For me it was my entire radio functionality. No radio, CD, Aux, Speakers. Nothing. Soon as I got that piece and figured out how to install it, everything worked like a charm
Currently thinking about going cobb Stage 2 on my 08 n54: catless dp, drop in air filter, 91 oct. How has your daily mpg changed throughout stock, stage1 & stage2?
Literally bought my 07 335i today. I only drive 30 miles a day. Hopefully i can get over 20mpg mixed city/highway driving once im Stage 2 in a few months. 26 sounds good to me :D
@ooganbooga69 were you able to find your problem? I have an 09 650i and the same issues but it’s not the satellite radio for me. I checked the amp, satellite radio, tcu, mulf, cd changer and I still didn’t find the problem
@ooganbooga69 you’re taking about the fiber optic bypass right? But which module was it? I’m having hard time finding the broken module in mine. It’s seems they’re all working
@@johnnyhovano1168 yes that’s the one! The one I bought on Amazon had an instructional video that I followed but it’s located on the left side of the trunk underneath the trunk liner. Hard to explain through text
Just came across this video, im having a similar issue with my e90, sat nav radio, parking sensors, everything works fine apart from the Bluetooth which is throwing up the sos fault code, will this fix my issue to?
My 2007 bmw 335i coupe doesn't come with a satellite. What else can I do to get my radio to work? And I just replaced my navigation screen display. And there's no sos on my dashboard either. Can someone help me out?
I installed a aftermarket head unit in my car and now get the SOS light. When I run diagnostics it says it's my phone system. Will this work for my situation? Also, you didn't show us exactly where to plug this thing.
@@YABOYNando I ended up getting Protools and coded it out with that. In my case, the factory Bluetooth system was triggering it because it now was disconnected. The new head unit has its own Bluetooth. But Protools got rid of it.
Thanks it looks like it will work for my e60 535 just one question, dose this mean there is no satalite radio (not that i care im just curious becuse this dosent seem to fix the cable just avoid it alltogether)
I bought one like 3 months ago and it didn’t work think it’s possible I have to buy another to hook them both up because I watched another videos and he said it could be that or another place
Some of the footage where I showed how to connect the cable in this video was corrupted unfortunately so i didn't have much to work with. However, if your audio system is out here's how to fix: 1. Remove connector from Satellite Radio module (red/green/black cables) 2. Insert optical bypass loop into the removed connector 3. Voila! Done!
Simply Car Things did this also fix your satellite radio? My car has all the symptoms you named. I’m going to try and do this fix and get my Bluetooth working again and my auxiliary port working. Also do you happen to know of the directions are the same on an E60 535i?
You forgot to show "where" that connector fits. Once you opened the trunk you described the parts but didn't point out where it is? Would you please? Thanks for sharing!
I had my 535i coded to turn off the BMW Assist and the SOS Display coded off yet I still get the SOS. I don't have Satellite so nothing to plug the MOST cable into. Let me know if you get it solved.
So I have a 06 BMW 330i I have sounds from my door opening, seatbelt sounds coming from turning on the car... But I have no sounds from my CCC Navigation unit. I have a new display and hooked up my phone and it plays but no sound I have the logic 7 Amo in the trunk.
It be nice if you can show a video on how to install it!
And show the problem and if it did get fixed.
My audio started cutting out and crackling a couple weeks ago. I disconnected the amp and cleaned all the connections and now it works perfect. Hasn't crackled since.
Did u also have the sos warning light
You didn’t even show how to plug that bypass..
Ahh yes the brains a good thing to use lol
Dude I removed the plastic around the plug in and presto it worked! Once again the UA-cam car gods have spoken and saved me $$$$$$ on repairs, thanks!
glad the video was able to help you man! Thanks for watching!!
