BMW 2007 523 CAS+ HELP!!! PLEASE OR IM DEAD !

[MonSter911]

GOOD DAY DK EXPERTS....... I HAVE TRY TO ADD KEY TO BMW. I USE BMW MULTI TOOL TO CREATE NEW ADDED KEY DUMP FOR CAS+. THERE AFTER I USE BDM TO WRITE DUMP BACK TO VEHICLE CAS. WHEN I WRITE DUMP BACK , I GET NO LIGHTS ON DASH BUT CENTRAL LOCKING, AND RADIO ALL WORKS PERFECT. ALSO VEHICLE DOES NOT ACCEPT NEW KEY OR ORIGINAL. SO I WRITE ORIGINAL FILE BACK TO CAS AND STILL THE SAME RESULT. I SUSPECT THAT THE NEW DUMP FILE THAT BMW MULITOOL SWITCHED IMMOBILISER FUNCTION IN FLASH OFF. I TRY CAS FLASH RECOVERY BUT STILL NO LUCK. I ONLY HAVE EEPROM FILE NOW AND I DONT HAVE ORIGINAL FLASH. HOW CAN I FIX THIS PROBLEM ?.......... MANY THANX CAS INFO :CAS 3+ OL15Y
61.35.6943835-101...........

WHY NOT ADD KEY BY OBD? I THINK YOU READ WRONG CAS,THAT'S WHY THE ORG ONE CAN'T GIVE LIGHT ON DASH,WHAT YOU NEED NOW IS A GOOD VIRGIN DUMP AND FOR DDE ALSO TO MAKE SYNCRO.

read cas correct.

please find attached as flash + eeprom

eeprom is original eeprom before adding key with bmw multi tool

flash is read this after writing bmw multi tool dump into eeprom.(when problem started)

can someone please check eeprm and flash. I suspect flash got corrupt.

[MonSter911]

thanx buddy... will give it a try tomorrow and report. everything works perfect on the vehicle except the dash and the key does not accept. will this allow the dash to come back to life ?

[MonSter911]

hello spiridonas..... no good friend. flash does not work. still no ignition on car.

use avdi,or autologic or icom,or inpa
- synchronizes
- re-progrs

ur problem is the small plug next to the big main CAS plug on ur CAS , check if the wires are connected well or if a wire is cut

[MonSter911]

Hi. Checked. Cables appear to be fine. I can't understand what went went wrong. All we did was write the EEPROM and when that no work we write original EEPROM back and vehicle is still no good.

There must be somthing from EEPROM.... read it bad and write it bad ....this make sense.... need a good dump and resync .

Good luck

[MonSter911]

I think eeprom is oki because ak300 picks up eeprom perfect. also bmw multi tool connects and reads all key information correctly including vin etc. this morning upon inspection I noticed original dump key positon 2 was disabled.... maybe this caused a problem with the flash. the first day when I add key to dump I selected key position 2 ( as bmw-multi-tool cannot make keyless key for position above 4 and original key was position 3.) so the new dump file had key added to key postion 2 (which originally was disabled). only afterr new dump added to eeprom did vehicle start giving problem
