PROCEDURE

For conditions that are similar to the situation described:

1. Verify the current I-level of the vehicle.

   Is the current I-level higher than ISTA 4.07.3x (I-level 17-07-507)? 

   YES-  Follow the diagnosis in ISTA

   NO -  Go to step 2.

2. Program the vehicle using ISTA 4.08.1x (I-level 17-11-520) or a more recent version.

   Note that ISTA will automatically reprogram and code all programmable control modules that do not have the latest software.

   Always connect a BMW-approved battery charger/power supply ( SI B04 23 10  ).
