Hey guys well long story short my tail light was lose and water got into my amp and damaged it. i was able to clean it up and revive it. And it worked btw it happened like 4 months ago. Any ways the other day i was listen to the radio and it was like crapping on me and boom the sound goes out. So i bought the fiber optic loop and tested the TCU AND AMP and everything worked .

The thing I got from the above is that when you loop out the
amp and the SOS light goes out it indicates the TCU/Mulf is
not the problem which in leaves the amp.

Hello all I have a 2006 330i (no navi or cd changer) and recently the sound to my radio went out. Upon checking for signal from the optic cable connecting to the amplifier, I see a red blinking light which is good. I then checked the connection for the telephone module and I noticed it had already been bypass looped (which is why I never had Bluetooth. My guess is that both modules are bad . So my question is can I bypass both the amp and the telephone module to at least restore the sound to the front speakers? When I plugged both bypass loops I finally get a connection at the optic connection under the steering wheel, I also have a red light when I connect my radio. Help anyone ? Looking for a bypass until I can purchase both modules let me know if I'm missing another module or connection somewhere as I can only find info on e60s.
