Thanks for the Your DIY! some information I saw in the E90 electrical system...
The steering unlock procedure:
1. The CAS2 senses the detection of a valid remote control_ID trasmitter. 2. The CAS2 Enables the unlock function.
3. The ELV performs the unlocking the steering procedure.
4. After the unlock procedure is done,the unlocking status is sensed by the Hall sensor, Hall sensor status reports to the CAS2 as a feedback.
5. The CAS2 switching off ELV module power.
The steering locking procedure:
1. Lock request to CAS2.
2. ELV module switched on.
3. Locking the steering by the ELV.
4. Locking Hall sensor feedbacks from ELV to CAS2.
5. CAS2 switching off ELV control module power.
Is it possible if we disable the Lock and unlock function by coding and remove the lock, we may need to fake or delete the Hall sensor status reported function to the CAS2? Since I do not have the tool I don't know.

Thanks for the info. Going to the dealer once I have some extra time to try and sort this out.
