2022 BMW i4 Combined Charging Unit Delivery Stop

Important Warnings for Owners and Technicians

BMW has issued critical advisories regarding this issue and the necessary repairs:

• Delivery Stop: "Do not deliver to a customer, a New, Certified Pre-Owned or Used vehicle subject to a Delivery Stop, until the vehicle is repaired. Do not use or sell replacement equipment/parts subject to a Delivery Stop." This means affected vehicles cannot be sold or delivered until the Combined Charging Unit (CCU) is replaced.
• High-Voltage System Safety: Working on High-Voltage (HV) systems requires specialized training. "Only properly trained personnel, who passed all applicable HV Technical Training Courses, should perform repairs which require disconnecting, or removal of High Voltage battery components on any Hybrid or Electric Vehicle." Unqualified persons performing such work risk severe injury or damage to the vehicle. Additional safety information is found in Repair Instruction 61 00...
• HV System Disablement: Before any HV component removal, the HV system must be disabled and secured by a properly trained technician with a minimum HV Qualification level. Once disabled, a "Blitz" - lightning bolt icon displayed in instrument cluster will appear.
