Comfort Access/Key Fob

[fordyc18]

Hi

Im still having issues with my key fobs not working at all, ive checked wiring through trunk lid, replaced with a good diversity antenna, My comfort access does nothing my seat doesnt save its positon via memory on seat, Battery in the car replaced and coded, im not getting any increased battery discharge warnings, Ive set the 2x brand new keys to comfort access key 1 and 2 blocked all the others. my key remotes dont unlock/lock the vehicle ever no matter how close i hold them anywhere.

 

I have notice when pressing the lock/unlock button on the dash locks good when it unlocks a get a few warnings on the dash, car running or not same outcome only when it unlocks. When running the rpm drops to zero but car still running fine and warnings on the dash come up.

Anybody Have any idea where i should start looking? wiring behind the lock/Unlock button on the dash is good as far as i can trace it, no faults relating to CAS or PGS/comfort access module, but all sorts of faults that just clear and dont come back unless i unlock with the interior button again

I take it both new key fobs are Genuine BMW? Footwell Control Module been checked?
