If you encounter instances on Model 220 vehicles, up to VIN A013772, of a battery drain condition, please perform the following steps. Only 220
vehicles with LF SAM (N10/6) part number 020 545 17 32 software version 12/0 are affected.
Check the quiescent drain of the vehicle according to WIS document AR 54.10-P-10301. The vehicle must be locked as the ATA is being checked and
