In the near future, I will try to see if I can have my car coded in the same way as if the column was replaced with one without a locking mechanism (as BMW did in their SIB). Before coding, lock will obviously need to be in the open position so column isn't permanently locked. This will likely work, but to be 100% sure it will never lock, I'll then reopen the column and remove the lock itself for the last time. I'll update the thread if I get this to work, it would be a nice permanent solution.
Bentley manual shows that the lock is wired directly to the Car Access System (CAS).
2 Lines in the CAS TRC Code seem responsible for the lock--makes sense that there would be one signal for full engaging and one for full disengaging:
Coding cable is in the mail!
there is another ELV parameter:
