thanks for all info! we are pretty good techs we use a powerprobe IV and test lights and checked every single fuse in glove box and breaker fuses on back and trunk ones and breaker sin the trunk many times with the powerprobe. its a very handy tool one of the best. But however i am gonna recheck them today because last night in my ///M the interior lights were intermitten and i found a fuse that was not popped but the wire actually cracked in half and was rubbing to make connection.. so i may just change every fuse today.
we tested the PRNDL switch with the chart it is sending the 12v as it should on every leg when selector is moved so were ruling that out. I have the DME data and the cluster indicator and shifter selector lights all working perfect telling me the car is in park, the only module that is not seeing park is the dam Immobilizer EWS which is brand new from dealer fresh programmed can read all data everything on it is functioning all key recocnized... So we strongly think what the tech at BMW told us that it is the trans controller AGS internal fault.. we may try to fix it probably a solder joint cracked...

but here is my question... the L2 powers the PRNDL switch 12v then it sends proper 12v as needed to the trans computer.. that must trigger and internal relay or something its the orange wire in plug 1 or end plug we have the 12v there and nothing coming out.. in the middle plug there is a blue wire that heads to the EWS. does anyone know what voltage that sends over there? is it 12v or it is reduced like a 5v refrence or is it 3.5v i have the scamatic here just dont know the volts.. i think if we hot that blue wire the module will accept P/N condition and the car will be fine i strongly think jumping the orange input to the blue output would fix this whole dam issue but i wanna know voltage first so i dont disrupt that ews box! UGGG
Thank you all! im rechecking fuses today after finding that weird one in my M5 last night!
also still have hard codes in this X5 that come back instantly not sure if they are related to this issue but these come back instantly and we checked every single plug!

airbag:
code 50 : supply voltage? no air bag light though

air conditioning:
code 0A AUC sensor? air works though?
Antilock brakes:
code 90: Intermitten system down?
those codes are hard they come back instantly even after leaving battery off for 5 hrs?? truck is killing us! lol we will not be defeated!
