HELP!!!!! my girl friend had her battery replaced in her 540i. While
inputing the security code for the radio she accidently input a Start
blocking code instead(i am not sure how) now she cannot start the car,
(although she did get the radio code in) can anyone suggest a way she
can disable/reset the start-blocking feature without a trip to the
dealership. Would disconnecting the battery reset the OBC ?? Thanks in
On older cars disconnecting the battery from ten minutes to several hours
would clear the codes (and all other memory).
Not sure this works on newer cars.
I once managed to set a code to xCxx by accidentally pressing two buttons
together - disconnection was the only way to clear this.

No, not from the radio, from the OBC.
Just have your girlfriend unlock the car from the OBC using the same
code she entered and then delete the code so it won't do it next time.
It's all covered in the FOM.
No not from the radio. that is the mistake, she put the some part of
the radio code into the OBC instead of the radio itself and now cannot
remember what part she put in which activated the start-block feature
for the ignition. H
