Hello all,

Hope someone could give me some hints related to a CAS change on a Mini cooper non S R56 2012.
Terminal 15 turns off constantly

DTC stored:
00A11E CAS ELV FAULT
00A0AF CAS PROCESSOR
00A0A9 CAS CONTROL UNIT FAULT
00A0AA CAS CONTROL UNIT FAULT
S0706 CENTRAL GATEWAY SUPPLY TERMINAL 15 MISSING

Im planning to buy a new unit (Blank), Just need to install and program? or there is more work to achieve?
Should I buy new keys? or is not necessary?


Thanks in advance

Try disconnecting Battery Negative Terminal for 30min than reset ELV with Tool32 clear codes and try to start car.
If you replace cas you will need to get ISN from dme and write to cas and flash to vin than add new key

Thanks for your answer.
Already tried that, but not success.
So a cas change sounds really complicated..
Is there an "easy" way to write isn to the cas module and add key?

To write an ISN, you will need a programmer (e.g. VVDI Programmer). First, you'll need try to write the eeprom and flash from your actual unit (make a clone) to new one, but if eeprom at your module is corrupted, you'll need you'll need to read ISN from DME/DDE(need to check if VVDI read your DME/DDE) and write into new ecu. Then you'll need key programmer to write keys into eeprom (to new ecu).

It's not possible to buy a "new blank" unit. CAS is always programmed to a VIN. If you get a new one, you'll have to order it for your car and it's basically plug-and-play (but you should code it nonetheless). Also, keys are already pre-programmed so you don't have to buy new keys as long as nobody did something stupid to the CAS before. A new cas costs a couple of hundred euro's, that's why some people assume you want to program a second-hand CAS which is not that simple.

Read and save the eeprom with R270, this might just be an ELV fault.
