Can You communicate with switch module under steering wheel ?
Check status of immo in BSI and ECU and post here

Steering Wheel Module? i haven't try

check photo posted....ECU locked...Match OK...wait synch with BSI...so,ecu wait to receive immo signal from BSI

Hi to all
new updates:
1-try to change BSM
2-try to change COM (under steering wheel)
3-change antenna transponder
4-clone BSI on bench without problem (Snif PIN)
5-when i write keys in bsi,pin is accepted,erase all keys and program 1st key..when try program key,bsi unable to inject code..so,the problem is always that bsi unable to recognize keys (F4BA error)
