2003 V70 awd, geartronic. 166,000 miles. been having this error message intermittently for a couple of months, sometimes on for 1 journey, next journey...no message...sometimes message on for a weeks driving, then off again.
ive checked for errors on vida and come up with these:
bcm-0094 communication problems with dem.

is there any specific module I should be testing further with vida?
is it possible it could just be water on connections on the rear diff cable connectors?
im new to using vida for diagnostics so any guidance to help trace the fault would be appreciated
