Multiple control modules on E60 fail to enter sleep mode, causing parasitic drain that flattens the battery overnight or within days. Common culprits include the CCC iDrive unit, telephone module and TPMS controller. Diagnosis requires measuring drain per CAN bus branch with a multimeter. Battery drain of more than 50mA after 30 minutes is abnormal.
