I'm hoping for a little help with my E90 2008 335xi. Everything in the car seems to be working fine except what is listed below.

A few weeks ago, I got the "SOS error" on my dashboard, there are no warning chimes, no bluetooth/phone, no radio, no navigation, no Central Information Display (CID), and can't eject CD/DVD.

I am wondering if the information below points towards replacing the interface box high (ULF-SBX-H) (would it being dead cause the no radio, CID dark, chime, no bluetooth/phone), a dead Central Car Computer (CCC), or something else entirely.

Given the information below, can anyone point me in the right direction?

- The three finger reset doesn't work.
-Fuse feeding the CCC (F56 in my case) shows around 14.5 volts at the terminal, and I have checked the fuse for continuity.
-The wire feeding power into plug in the back of the CCC (X13812, pin 15) shows around 14.5 volts.
-The 20A fuse on the back of the CCC shows continuity.
-I occasionally see red light from the #1 fiber optic cable leading into the CCC.

I have been using the Bavarian Technic cable/software to try and troubleshoot the problem. It is persistently returning the following from the Instrument cluster PL2 E8x and E9x

Current Fault Codes
A554:
Alive telephone
Error will not cause a warning light
Error is currently present
Test conditions have been completed

A559:
Clamp 30g_f cutoff
Error will not cause a warning light
Error is not currently present
Test conditions have been completed

Can any one give me any ideas on where to go from here? Would a dead box somewhere on the MOST network cause the CCC/CID to be COMPLETELY dark and non-functional?

so you may try to access ccc module and read error codes from it

I don't know how to access the CCC because it doesn't response at all during the Bav Tech module short test.

I get "No faults found" from the "Central information display" & "Central control unit (CON)" module short tests, but no repsonse from "Business Radio / User interface (CIC / CCC-BO / M-ASK-BO / RAD2-BO / RAD)" or "Professional Radio / User interface (CIC / CCC-BO / M-ASK-BO / RAD2-BO /

"MOST / CAN gateway CD73/MD73" also reports back as "No faults found"

What am I missing? Would a failed module on the MOST network take down the CCC entirely?

I really don't want to resort to a stealership, but I'm about out of ideas.

Has anybody got any suggestions at all?

so your CCC partially died
almost all CCC headunits die due its complicated construction and time
you have 3 options
send your CCC headunit to repair
get used CCC headunit used or new, if you to go this way make sure you are getting unit with 8 programmable buttons because these are newer and more reliable
get used CIC upgrade kit from bimmertech or junkyard or ebay

Thanks for the advice... maybe a little more?
You agree with my assessment that the CCC died? Based on the details, it is unlikely to be anything else (like a faulty unit on the MOST)?

Any suggestions on where to get the CCC repaired?

this is one example

but it is more viable option
