SOS Failure

[ssandison]

Hi,

I have an issue with SOS call failure message coming up on my X5 E70 4.8i.

I posted another thread about my leaking panoramic sunroof which I believe is responsible but I want to put that to one side for the moment as I haven't seen any further leaking since I tilted/vented it.

I have been trying to get the radio working again by bypassing the TCU which didn't work.

My error codes are:

A670/present - FZD: Signal line, fogging sensor
E484/present - SMBF: K-CAN line fault
A1 A3/not present - CCC-ASK: Control-unit fault
E5C4/present - CID: K-CAN line fault
9CC5/present - FRM: Mirror heating, driver's side faulty
A559/not present - Instrument cluster: Supply was switched off (terminal 30g_f)
A554/present - KOMBI: No message (telephone)

I've tried putting in a new battery, checking fuses, using a MOST bypass etc but nothing works. Is anyone able to point me in the right direction?
