Why not take off the cem and clean it first.
My diag reader sent me loads of crazy error messages when plugged in before i cleaned the cem up using contact cleaner and a toothbrush.

yes i was thinking i might as well take a better look at it did take of the cover and unplug the two top plugs all looked dry and nice
maybe i should take it out for a better look ?
not a nice job buy maybe have to.
the fuses on the inside of the car in the cem i have not checked yet to see if there ok so next job i think is that also.
thank you for your inspiration.

Hi

Its not as difficult as it looks, well not on my S40.
Mine failed the mot due to the mil "not" coming on at start up.
After trying out a new display unit with no luck i resorted to the cem clean.
This fixed it although the cem showed no signs of any faults.
Remember to disconnect the battery first, then make a note of what goes where then take the unit off the car.
Use good contact cleaner and a softish tooth brush to clean the connectors.
Also remove clean and refit each fuse.
When refitting take care not to unclip the holders as i did!!!.
Also leave a window/door open before taking off the battery.
Good luck, did mine 18 months ago and no more issues.
I have a hunch that on the S40 cem wires get dislodged when pulling it around during the cabin/pollen filter change.
