BMW cas3 problem

[Zhed]

Hi,

I have a car with cas3 but there is suddenly no ignition with the 2key. I have communication with car by diag. I try all function of ista (reset, ELV counter,...) but nothing, no ignition. I read with Xprog the 9s12 (eep and flash), put the file in bmw editor cas3 but eep seems to be OK. I make some search but solution are always the same, clone CAS3 or corrupted file...

Could someone could help me to fix this problem or does someone have original file from this CAS

thanks for help

post details of cas and ecu eeprom. did u synchronize cas = dde ? first do it first. what kind of errors are in cas and ecu?

[Zhed]

I have no fault code. To synchronize cas-dde you need a least ignition, here no ignition so no sync possible with ista

thanks

Same ISN in CAS and ECU. Can key2 be used to operate the locks?

[Zhed]

Hi, i have only one key

[droidwayne65]

Thought you meant key2. Does the key you have operate the locks?

[Zhed]

No, nothing happened. no 1st ignition if i use the cas from an other car, 1st ignition is ok but no second, normal...

Maybe the key is simply broken? Can you read the transponder ID with a generic tool and does the key transmit a signal if you press one of the buttons?

Tried cloning it?

[Zhed]

yes, that's the first thing i tried

[Zhed]

Problem is solved for now but i don't know why. I try IBS, Comfort access module unplugged,.....but always problem. the last try, all plugged, i have ignition and car start. I reset ELV counter and CAS, i'll see

thanks for your help
