Later model BMWs with fob-style key (that do not insert into the steering column and turn to unlock the column and start the engine and vehicle systems) employ an electronic steering lock assembly.  The lock/unlock function is electrically operated when the key fob is activated and the ignition is turned on.

Typically, when the system sees a fault, the yellow warning light will come on in the Check-Control display Ignoring  the fault warning can result in a no-start situation if the lock assembly fails altogether. Obviously, addressing the fault during the “yellow” warning stage is recommended.  Once the system goes to a red warning, the engine will not start.

The first stage in addressing a yellow fault warning is to reset the ELV counter.  This is done using a full access diagnostic tool, such as a well equipped independent shop would have.  Additionally, the system fault codes should be read, using the same tool.  If an actual fault is found, address the fault.  Faults may be at the the actual ELV column lock assembly, the CAS (Car Accessory System), ESL circuit (Electronic Start Lock) or other electrical faults.
