2023 BMW i4 / i7 Combined Charging Unit Delivery Stop

Important Warning for Owners

BMW has issued a critical advisory regarding vehicles subject to this 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 any affected vehicle currently in dealer inventory cannot be sold or delivered until the necessary repair is completed.

Symptoms of the Combined Charging Unit Issue

Owners of affected 2023 BMW i4 or i7 vehicles might experience issues related to the Combined Charging Unit (CCU). The primary symptoms include the charging process being aborted unexpectedly or the vehicle being unable to start. In rare and more severe cases, a high-voltage system failure could occur, causing the vehicle to coast while driving and eventually come to a stop. These issues stem from the BMW i4 Combined Charging Unit not functioning correctly.

Cause of the Malfunction

The root cause of these problems is that the Combined Charging Unit (CCU) in the affected vehicles may not have been manufactured to specifications. This manufacturing defect makes the CCU prone to moisture ingress, which can lead to its malfunction. This moisture intrusion directly impacts the performance and reliability of the BMW i4 Combined Charging Unit.

Repair Procedure Summary

The correction for this issue involves replacing the faulty Combined Charging Unit (CCU). The repair procedure is detailed in BMW's Repair Instruction REP 61 42 501. After the CCU replacement, the vehicle will also undergo programming and encoding to ensure all control modules have the latest software I-level. This comprehensive approach ensures the new BMW i4 Combined Charging Unit operates correctly with the vehicle's systems.
