Turned the car on this morning and my iDrive won't boot up. It brought up the BMW screen and that's it.

Turned the car off, waited a few seconds, started the car again, same problem. Press "Alt Cntrl Dtl" to reboot, same problem.

Decided to drive to work and it was rebooting itself as I drove every 2 or 3 minutes but still the same problem.

Any idea WTF is going on?

This Service Information bulletin supersedes S.I. B84 08 05 dated June 2005.

(New) designates changes to this revision

SUBJECT
CCC - CID Switches Between BMW Banner and Blank Screen


MODEL
E90, E91 (3 Series) with SA 609 Car Communication Computer (CCC)

E60, E61 (5 Series) with SA 609 Car Communication Computer (CCC)


SITUATION
The customer may complain that the Central Information Display (CID) switches between the BMW banner and a blank screen (resets). One of the following fault codes is stored:

(New) CCC-A FC "A468 LVDS cable break"

(New) CCC-BO FC "A3E4 fault in file system"

CAUSE
CCC Failure

PROCEDURE 1 (CCC-A FC A468)
On a customer complaint basis, and only if the above fault is stored, replace the CCC.

(New) PROCEDURE 2 (CCC-BO A3E4)

In order for this procedure to work properly, DIS V44 and Online Update "DIS_UPDATE_12.4_" must be installed on the DIS/GT1.

This procedure will only work if "CCC-BO FC A3E4 fault in flash file system" is stored. Do not clear the fault.

Perform a short test on the vehicle. If the CCC-BO is not recognized during the short test, perform an individual test on the module. The CCC may be resetting at the moment.

Page right and identify if "CCC-BO A3E4" is shown in the listing of faults. Switch to "Control unit functions" and select CCC-BO.

Select Identification and note the "Function software" from the "messages and results" box.

If the function software is 5.83.9, continue with the next step. If the function software is not 5.83.9, replace the CCC.

Page right and select DIS test plan "CCC complete B6512_50013"

Continue in the test plan until the screen "under fault evaluation A3E4 Control-module fault in CCC. Resetting CCC." At this point the flash file system is being corrected. It will take about 15 seconds to finish

On the next screen the following results are given "A3E4 Control module fault in CCC. Procedure: reprogram CCC (CCC-BO, CCC-ASK, CCC-A, CCC-ANT, CCC-GW)." Make a note of the GWCODE (warranty code) for vehicle programming in the comment box of the warranty claim.

Verify that the flash file error is corrected by ensuring the CID is shown on the BMW Banner and is not cycling. One reset may occur after the test plan has finished. After 3 minutes the system should be stable and not reset.

Update the complete vehicle per SI B09 05 01 (Coding, Individualization, Programming) Procedure B, using the latest version of Progman.

Covered under the terms of the BMW New Vehicle Limited Warranty.

Thanks for the info cobradav, once again!

Thanks for this ...

I've just been told by my SA that it is not my CCC but software related to my CCC. There is a patch to resolve this issue but it won't be available in NA for two more weeks. So I have to drive the car as is until the software fix is received and loaded into my car.

They say it won't damage my car.

I just don't see it, I do think its the CCC. But in away, hope that it is software because if a CCC can break this easily, I'm not sure how long I will keep my e60 when coming to the end of warranty.

I suspect there have been many CCCs replaced that may not have needed it and could have been software as your SA is indicating. There is also a new SIB out on CCCs which I'll post here as well. BMW probably had the OEM of the CCC modules investigate and they may have found many with "No Fault Found" leading them to conclude it may be software related. It will be interesting to follow this issue to see just what conclusion is found and just what software attributes are being corrupted if that is the case.

SUBJECT
Enhanced Support for CCC Car Communication Computer

MODEL
E60, E61 (5 Series) with SA 609 CCC-Navigation

E63, E64 (6 Series)

E90, E91 (3 Series) with SA 609 CCC-Navigation


SITUATION
In order to enhance customer satisfaction of BMW convenience systems, a special new process has been developed that is designed to identify the root causes of customer complaints relating to CCC issues. The development of this new process was necessitated by the fact that analysis of the large number of returned parts failed to identify the cause of the original customer complaint. Once the root cause is determined, the defect eradication process can begin.

In order that you get an immediate response to your PuMA cases, 3 additional Technical Hotline specialists have been dedicated to this new process.

This enhanced support is for the CCC related complaints including the following:

Navigation system

Audio system

Voice activation system

Programming/Coding of the CCC.

PROCEDURE
From March 1, 2006 before any CCC is replaced on any model BMW listed in the "MODEL" section of this bulletin, authorization must be obtained. To obtain a replacement authorization, A PuMA case must be submitted (start with "CCC" in the subject line). A replacement authorization will be given in the PuMA case if the Technical Hotline Specialist agrees that the module is faulty. Refer to SI B00 04 02 (BMW Group Technical Hotline) for details on creating a PuMA case. This includes previously released Service information Bulletin's that require CCC replacement.

Before creating a PuMA case:

The technician assigned to the vehicle must have training directly related to the vehicle or system in question.

All available resources must be reviewed. These include but are not limited to: service Information Bulletins, Service Measures, TIS, Service Technology Bulletins (SBT), DCS messages, Service Round Table, Training manuals, Repair Manual Instructions and DIS Functional Descriptions (F. It is the center's responsibility to be familiar with published technical information.

Required checks must be performed. For example, diagnostic test plans, verifying circuit integrity, power and grounds, and reviewing vehicle service history.

The shop Forman/Team Leader must be consulted.

The vehicle must be in the shop. In order to aid the Technical Hotline Specialists in diagnosis, your diagnostic tester must have transmitted FASTA data indicating that all relevant test modules have been completed. Do NOT perform quick delete or delete any fault memory before transmitting FASTA data.

WARRANTY INFORMATION
For vehicle repairs carried out on March 1, 2006 and later, replacement of a CCC without prior approval will be subject to debit. When submitting a warranty claim for a CCC replacement, the PuMA case number and the Replacement Authorization Number must be specified in the comments section.

I'll let you know what comes out of this mess ...

Freewilly

Had this problem few times before. After I got out from works, my iDrive is back normal again.

The problem went away since I upgraded to CIP 20.x

Canada545

Ya, but for two weeks I driving around with no radio/cd, no bluetooth (phone), no navigation ... not good!

Freewilly

2 WEEKS!! That's too long. My problem went away in few hours.
Hopefully the software fix your problem like your SA promissed.
