HELP! EGS line disturbed - No CAN Communication

[jopecasa]

Good Day!

My X5 went on Limp mode and Trans fail safe flashed on cluster.

Died on uphill while I was flooring it around 90kmh.

Got stuck on a very dangerous bend and had to get the missus out and placed her safe and secure....she's not happy!

Tried to start... nothing!

Tried calling for a tow truck and unfortunately they said they'll be here in an hour and 45 minutes..ugh!

So I checked and lifted the bonnet....motor looks good and no funny smell.

No diagnostic pc with me at the time....

After 40 minutes waiting ....tried again....fired up and started...but

trifecta lights.....TMPS .....engine light...airbag light...suspension inactive..and so on...sheesh!

So i drove really slow and avoided traffic and took the back roads.

Finally got home and loaded INPA and scanned for errors.....

No Communications on DME - LEW - DSC - etc...

But cluster and and other modules not on the Power Train CANBUS all working.

INPA IM readout ---- came out as EGS line disturbed - No CAN
Communication.

First checked relay and fuses...ALL good.

Battery and alternator - OK ---voltage stable


Disconnected the following in order:

1 Steering angle sensor - no good
2. ABS module - no good
3. DME - no good

not yet done:
Mechatronic connector
YAW sensor
other modules?

So tired and frustrated ....and will check again tomorrow morning.

Please help this is the first time ....Betsy(X5) let me down.


Sorry for the long post...
