BMW M5 F10

Hi, desperate for any info possible.
Started car dash lit up all warning lights,no speedo stiff steering no mileage increase recorded,so i changed and registered a new battery,no change whatsoever,had diagnostics done,a whole array of permanent codes that couldn’t be reset DME/DDE,EGS,EDC,MRS/ACSM KOMBI etc etc and so on,checked fuses no apparent faults.
The garage has now refered me to a bmw specialist who cant see the car until mid March,does anyone have any ideas,maybe anything i can check,the car is almost fully loaded extras wise this includes comfort access.

Thanks guys.

Maybe a long shot, but I would take both battery terminals off short them together for ten minutes.Put it back together.See what happens

What are the permanent codes? Seems like you haven’t lost communication with any modules but high possibility that there’s a bad module bring most of them down.
