SOS Call System Failure!

Hi, this is so exciting, my first problem with a car.

I was immediately presented with a yellow telephone icon with a stripe through it with the following text, 'SOS Call System Failure!'.

The car seems to drive as normal, I-Drive reset to default and was extremely sluggish, plus the CD system wasn't playing game.

So I search the forum and did the reset thing (pressed the DVD, CD and volume button together), I get the same SOS message but I-Drive is back to normal response levels. The message is not in the user manual and the BMW contact has no idea what it means!?!

So maybe my M6board buddies can shed some light?

I had a similar message at the start of my CCC failure.

Another CCC Failure

Good luck.

Hi,

I spoke with a large BMW garage in Germany and they were extremely helpful. They said the message most likely relates to an issue with the bluetooth connectivity and that I needed to remove my mobile from the iDrive and re-connect and phew, it was indeed the issue.

So, for the record, if you get such a message (SOS Call System Failure!) and it additionally messes up your iDrive, action the following steps:

1. Depress the CD eject, DVD eject and CD volume knob simultaneously until the iDrive screen blanks out.
2. After iDrive reinitialisation, remove your bluetooth mobile from the iDrive menu
3. Switch off, not sure it's necessary but that's what I did.
3. Switch back on and re-config your mobile back into the iDrive.

My journey back home tonight will consist of turning up the CD volume and listening to 'ATB - These Days' in repeat! That song was made for the M6!

Thanks for your response Paul.

Hi,

Currently I have the same problem. After turning on the car iDrive says "SOS call system failure". And after the error goes away when I'm trying to access the telephone in Communication, the system says that "Mobile phone not installed", however it's possible to call from the phone tube. This appeared after my car was for service in dealer... there was no problems before. They don't want to accept their fault. Now trying to get proof for this to get back all stuff working.

Best wishes,

Karl

Sorry, but I went one better.
After driving the little one back from school the idrive went completely blank, and no recovery what so ever.
No radio, cd, nav, etc.
Tried rebooting and nothing happens.
Booked the car in for tomorrow morning, and at the same time I will get the oil and filter changed and also fit an ipod connection too. I will drop in a line once I get the car back to let you know what was wrong, but as suspected it is the ccc.

i'm having the same issue, car has been back to service 3 times to fix this. I have not tried the fix that is listed in this thread so i'm hopeing that works.

Just a note: mine locks up for about 15 min then it resets on its own. Also i didnt have this problem till i upgraded to version 27 software.

just checked and i dont even have bluetooth on and still having the same exact problem.

I don't think that is relevant RedM6, it is it's time to go, and it just started happening now.
Mine was upgraded to V27 last March, with no problems at all until now, and then all of a sudden ...darkness!
When you go in the BMW garage tell them that it also happend to a friend and it was the ccc unit that had to be changed.
They will change it under warantee, I hope, I will find out on Saturday morning when I pick it up.

SUBJECT
SOS Inactive Warning Message, No Communication with TCU


MODEL
E60, E61 (5 Series)

E63, E64 (6 Series)

E65, E66 (7 Series)

E70 (X5) vehicles equipped with ZPP (Premium Package) or SA639 (BMW Assist)

E90, E91, E92, E93 (3 Series) vehicles equipped with ZPP (Premium Package) or SA639 (BMW Assist)


SITUATION
A check control message stating the 'SOS inactive' is displayed.
  • The Telematics Control Unit (TCU) is NOT identified when performing a short test using the DISplus or GT1.
  • If the SOS button is pressed the call connects but the radio is not muted. The BMW Assist™ phone calls audio comes from the emergency speaker.
  • Bluetooth: An approved Bluetooth® enable handset which previously worked no longer connects to the vehicle. The Bluetooth menus for pairing a device to the vehicle are unavailable.
  • RAD2 vehicles: The BMW Assist icon and phone icon are missing from the Radio display.
  • CCC vehicles: Enable Services is grayed out.
CAUSE
  • TCU Hardware failure.
  • MOST-bus communication issue.
  • Incompatible handset paired to the vehicle.
PROCEDURE
  1. Duplicate the complaint.
  2. Does the customer have a Bluetooth handset paired to the vehicle?
    • If no, proceed to step 3.
    • If yes, obtain the following information:
      • Manufacturer of the handset
      • Handset model number
      • Software number
      • Does the problem only occur when a handset is paired to the vehicle?
Note: Pairing on an incompatible handset can have adverse affects. Please refer to the 'Compatible Handset Information' section of this bulletin for more information.
  1. Check the BMW Assist account status on DCSnet. The BMW Assist services expiration date and the TCU activation status can be checked on DCSnet under Service/Vehicle History Inquiry. Refer to SI B02 01 06 (Updated DCSnet Vehicle History Inquiry information on BMW Assist) for more information.
    • If the customer has an active BMW Assist services account, test the BMW Assist services following the information outlined in 'Testing of BMW Assist Services' section of this bulletin.
  2. Perform a short test using the DISplus or GT1.
  3. Is the TCU identified when performing a short test?
    • Yes, proceed to step 6.
    • No, are any other MOST-bus modules identified?
      • Yes, check power, ground and the MOST-bus at the TCU.
      • No, perform a MOST-bus system analysis.
  4. Work through any MOST-bus communication faults. Diagnose and repair as necessary.
    • Check the MOST bus splice point for connection problems.
    • Check the MOST-bus optical connection. E.g. were the OPS/OPPS head is connected.
    • If anything was retrofitted on the MOST-bus (E.g. CDC, i-Pod, S-DARS, etc.) check the connections at the module that was retrofitted.
  5. If you can not duplicate the customer complaint and there are no MOST-bus communication faults, refer to SI B84 16 07 (Erroneous SOS Inactive Warning Messages).
  6. If the DISplus/GT1 cannot communicate with the TCU, power and ground are OK at the TCU and the MOST-bus communication is OK; the TCU should be replaced. Proceed to step 9.
TCU REPLACEMENT PROCEDURE
  1. It is NOT necessary to obtain a Part Replacement Authorization (TeileClearing) for this specific issue. Refer to the Warranty section of this bulletin for more details. Additional information can be found in SI B84 23 05 (Enhanced Support for BMW Assist Telematics Control Unit (TCU) with Bluetooth & CPT9000 Phone Systems).
  2. Refer to TIS (RA 84 11...) for the TCU replacement procedure.
  3. Before installing the new TCU, remove one copy of the Electronic Serial Number (ESN) label and place it on the repair order for reference during warranty claim entry. You will be asked for the new TCU "ESN" when submitting a claim via DCSnet. Refer to SI B01 10 05 for more details.


  1. The second ESN label of the TCU should be affixed over the existing label in the Owner's Manual insert (P/N 01 49 0 157 963).
  1. Complete the TCU installation
  2. Using Progman V26.01.00 or higher, program the complete vehicle. Refer to SI B09 05 01 "Coding, Individualization and Programming", Procedure A.
  3. Initialize BMW Assist following the procedure starting at step 16.

I just replaced the TCU but the error message still remains...
The TCU was already coded to my VIN before it was sent to me.

So i'm just wondering...
Is there something that i have to do before the sos call error message disappears?
