TSB, SOS Failure

Post by steve140 » Sun Jan 27, 2019 8:08 pm

Got the dreaded SOS failure however luckily the car is under warranty.

Its needs the TCB control unit replaced and after the having the car all week they have told my wife that the part is on back order and no idea how long it will be......great service!

Anyone else know much, thinking this might be a common issue with a part that is in need of a redesign hence the delay.

The symptoms are :

SOS call failure message
No Sat Nav
Can't reset the trip meter
No bluetooth phone
Lost all settings re numbers, radio stations etc.

Car is a 66 plate M140i 5 dr

Hopefully this isn't across all BMW's as my 5 series is now just out of warranty!
