Yes you can splice fiber optic cables to repair them but you need special splicers and special tools to ensure the light inside the fiber is aligned.

Honestly it is probably cheaper to replace the entire harness it is a part of than it is to get all the tools to splice and/or repair that...

How much are the tools. And I would rather replace the entire harness but having a hard time locating where they go. So far I've traces a set of wires near the driver side under the carpet. How much further do you think they go?

Probably easier to buy a new cable.

Where does that end plug in.
Or if you do not have CDC there may be some extra cables
for pre wiring already in the car and not used for 09 an earlier
models.(that you can use to replace it)

How did you discover this what part of the car is it coming from
and what kind of sound system do you have.


It would be normal for light to shine on only one side as
the other side is the return loop.

A pin on the connector housing frees the two cable for removal then
only the damaged one needs replacing.

Read about the most bus in the following pdf all the lines come together
in a routing block under the Passanger seat Bolster on Drivers Side (US )

See page 26 to 29 first document.

Splicing Fiber Optic is not cheap, and the tools for it are even more expensive.

I was a PM for an electrical contractor that did some fiber splicing. Our splicing machines were $10k a piece... We did industrial type splices though so not sure what smaller splicers would cost, but im guessing in the $2-3k range.

However, it isnt too bad to pay for a splice considering the cost of tools for a fiber splice. Ask the dealer and see what they charge. Or call up some fiber companies and see if they would consider helping you.

yeah, it's pretty easy, actually. we do it all the time. you just need a clean cut, some new pins, and a connector.

BMW uses mechanical splices and connections. Why would there be an issue? These are factory parts.

Hey I just started reading the PDF file. Those wires that are cut run to the amp in the trunk. I noticed about 4 green cables are damaged. I was thinking about soldering the speaker wires. But the fiber optic ones, was thinking about replacing them. There are some wires running to nothing under the trunk. Not connected to anything. I found a panel near the side or the rear seats but it seems like the fiber optic cables run towards the head unit.
I'm in Brooklyn New York.

Fiber optic wire replacement.

Any idea on how to remove the fiber optic wires from the connector?
