Awesome! I've been fighting a broken loop for over 6 months, and thanks to this I was able to track it down in about 10 minutes! I knew how some of this worked, but your demo of the E60 diagnostic light was the key that helped me. Ended up being my SIRIUS unit. I removed it, looped past it with a homemade loop and instantly got sound. Thanks so much!!!

Thanks !!! Im in Japan and this video saved me time and money! Cheers!

Thanks for that detail explaination you're the first KZread that it's very thorough

what a simple but effective tutorial ! thank you

thanks so much, you just saved me $2390 from the dealer and some other dudes who said i need to code the amplifier

Question - Recently bought an 08 528i. Sos malfunction on along with aux & cd greyed out, with no sounds from the radio at all but I can hear the radio fan on & sometimes slight static from passenger side speaker. When I unplug everything I get a red light on the amp connector, plug that in & yellow light flashes on bottom of the amp but light moves to satellite, then to the telephone control module but when I check the head unit connector in my glove box I have no light from it at all? Tried bypassing each unit one by one but got nowhere. I checked all fuses & they were good. Any suggestions ?

I have the same problem but with my F10 535d. could you make a video on that car aswell or help me out in some way?

Robert Crockett , I have the same thing! I just got a 2006 BMW 750 LI from a friend of mine, there is no sound in the car, I noticed the trunk doesn't lift by itself, some components are missing in the trunk, the wires that go to the DVD changer are mutilated, and there is some kind of oil spilled by the section where the components are, and now I know where it comes from! The damn lift! I don't know what else I am missing in the trunk, and I would love to get some sound in the car!

Saad Chiguer Hopefully I can get some sound in a few weeks. Might just get something to bypass this Optic Bullshit

So question I have fiber signal to both the satellite receiver and to the amplifier yet still no sound. All fuses are good. Working in a e70 with top wifi 2008 x5 48i. Any tips or should I just get the loop bypass to figure this out

I just bought a 335i with the top hifi. I also have light to all objects but no sound to anything. I did find a broke fuse(40amp) in the trunk and when I replaced it. Instantly popped and amp smoked. Tore it out and the board was already previous fried. Have a new amp being delivered next week. I can let yah know if that was my issue, but I'd recommend looking for the light inside like on the video to see its properly being powered or even bust open the amp and see if you see any issues

Hi mate, thank you for your video. I found my red light signal but its steady red and its not flashing. Does that mean its bad?

Did you figure what the problem is? I am having the same problem now, the loop is closed, the amp is showing constant red LED light, fuses are all good. No sound what so ever.

They always break under seat because it is movable and sometimes from the module itself

Urgent advice with regards to bmw e90. My car stereo and chimes arent working. The stereo itself wont turn on but the cd ejects fine. I have checked the MOST fibre optic loop connections. The one going to stereo unit show red light. The one connecting TCU has no light neither does the one in glove compartment. Which module is the issue, and where would i connect yhe female loop connector to complete the fibre optic circuit?

Juanamo FPV if stereo doesn't turn on, you need to get it fixed first. You have navi ccc unit, correct?

Logic7repair i presumed it wasnt working because of the broken loop. nope its the entry level professional version. no sat nav and theres no amp in the back.

Juanamo FPV, so if you have no fiber optic amp, your head unit plays all the speakers then.

@robjuanamo7563

Logic7repair yes. so is the problem more likely to be my stereo rather then the fibre optics?

Need help with order. I have an E65. I did not pull the amplifier. I see light on the satellite, telephone, and navigation. No light on the OPPS. Does the order go Nav>ASK>OPPS or Telephone>ASK>OPPS? I cannot find a schematic.

UPDATE: I do get light from the OPPS connector when I mash on the buttons on the ASK.

What happened if you have piping speakers like there’s sound but they just pop and it doesn’t sound right
