Could you good people tell me what does this mean

I have an Exclamation mark ! displayed on the small information screen on my 530i E60. Not the NAV screen, but the small screen between the Speedometer & Revcounter. There are NO Error messages appearing at the bottom of the Nav Screen.

However, when I start the engine, I get a message (again on the small screen) saying SOS with a Line across it (as if to Say SOS not working).

I have Bluetooth, and it is working fine with my mobile phone.

Any ideas?! Thanks

why not try pressing the SOS button? It can't hurt

There is another posting "Recall" that may be referring to your issue. There was just a recall letter sent out regarding replacing the TCU for BMW assist that may be causing your problem.

My wifes car started that also. Had it at the dealer two days to correct, picked it up last night drove 3 blocks and SOS came on again! Someone dosn't know what the hells going on.

You probably need a new TCU Unit. I had 4 installed before they corrected the same problem. Hit the SOS button to see if it works,if it does ask for a location. Good luck
cheers
