2022 BMW i4 Electrical System Fuse Issue
A manufacturer communication for the 2022 BMW i4 addresses an incorrect fuse assignment in the compressor circuit. The vehicle may have a 30A fuse (F227) where a 40A fuse (F229) is required for proper protection.
What's the Issue?
Owners of the 2022 BMW i4 should be aware of a specific electrical system concern identified in NHTSA Manufacturer Communication 10214986. This communication highlights an incorrect terminal assignment within the vehicle's electrical system. Specifically, the compressor circuit, which is crucial for various vehicle functions, is protected by a 30A fuse located in slot F227.
However, the correct and required fuse for this circuit is a 40A fuse, which should be assigned to slot F229. This discrepancy means the compressor circuit may not have the appropriate level of electrical protection.
Why This Matters
An incorrectly sized fuse, particularly one that is undersized, can lead to several problems. A 30A fuse protecting a circuit designed for a 40A fuse may blow prematurely under normal operating conditions, leading to unexpected loss of function for components connected to the compressor circuit. While a blown fuse prevents potential damage to the wiring, it can also cause inconvenience and unexpected vehicle behavior. This 2022 BMW i4 manufacturer_communication addresses a fundamental safety and operational concern.
Repair Procedure Summary
The resolution for this issue involves correcting the fuse assignment. Technicians need to ensure that the compressor circuit is properly protected with the correct 40A fuse in slot F229, replacing the incorrectly assigned 30A fuse in slot F227. This procedure ensures the electrical system operates as intended, providing reliable protection for the compressor circuit and related components.
