Do first gen BMW ‘smart’ keys fail?

[ard]

I wonder if a cas module was water damaged and is filling up the bus with garbage commands. Too much and it stops. Then you reset, works for a while...then not.


There was recently a post about the door handles and how the system would react to a bad handle- same deal, eventually the one bad handle 'used up' the allotment of bad data, module turns off.


Just a WAG

I've never purchased a CAS key but E39 and E70 keys were much cheaper with the BMWCCA discount. Worth checking out perhaps.
