Service bulletins for the 2023 BMW i4

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

B1205232024-03-02. Service bulletin. POWER TRAIN. The customer states there is a Drivetrain Malfunction message displayed in the instrument cluster. In addition, the following fault memory entries are saved in the CCU (Combined Charging Unit) 0317F2 - High-voltage system, insulation fault detected: when switch contactors are closed. 0317F1 - High-voltage system, insulation resistance below warning threshold: when switch contactors are closed. The fault memory entries (isolation faults) can occur both individually and in combination and must be traced back to the eDrive motor based on the ISTA test procedure. If ISTA test procedure lists possible cause of fault as; A metal chip is found behind the brush module (between the brush module and the end shield of the electrical machine). Repair required. Refer to service solution no. 20000794435083 in Aftersales Information Research (AIR). Follow information in the Procedure section below.
B6402242024-02-01. Service bulletin. ENGINE AND ENGINE COOLING. The coolant changeover valve may develop a coolant leak when the outside temperatures go below 19°F (-7°C).

B6125232023-11-01. Service bulletin. ELECTRICAL SYSTEM. The purpose of this Service Bulletin (SIB) is informational regarding DC (direct current) charging complaints on Gen 5 Battery Electric Vehicles (BEV). It serves as a supporting argument and is intended to help distinguish between a standard designed function or component operation from an actual system fault in a DC charging customer complaint (i.e., “DC Not charging or “DC charging too slow”. Helpful “Tips and Tricks” have been included on each topic within the document that can be used as reference to aid in the diagnosis or in understanding the system. The situation involves several possible causes: 1. Limitation of charging power by the charging station or charging app configuration. 2. Decreasing charging power at a very high state of charge (SoC). 3. Too frequent DC charging attempts within a short period of time. 4. The high-voltage battery is not at the ideal temperature. 5. Ageing of the high-voltage battery.
