BMW has issued Service Information Bulletin SIB 64 11 24 to address a potential issue with the coolant changeover valve in certain 2023-2024 BMW i4, i5, and i7 electric vehicles. This service action aims to prevent coolant leaks that can occur in very low outside temperatures.
The Issue: Coolant Changeover Valve Leak
Quality checks have revealed that the coolant changeover valve in affected vehicles may develop a leak. This issue is particularly prone to occurring under very low outside temperatures, specifically when temperatures are significantly lower than 32° F (0° C).
When this occurs, the vehicle may experience "coolant loss" due to the "Coolant Changeover Valve(s) is leaking". This condition necessitates a repair to maintain proper vehicle operation and prevent further issues.
Campaign Statuses and What They Mean
BMW uses specific statuses to indicate the condition and required action for this service campaign:
- Status 40: This indicates that predictive analytics monitoring is active in the background, and the vehicle has not yet experienced any issues related to the coolant changeover valve. No immediate action is required at this time.
- Status 00: This status signifies that predictive analytics monitoring is active, and a leak in the coolant changeover valve(s) has been detected, resulting in coolant loss. Vehicles with this status require the coolant changeover valve(s) to be replaced.
Repair Procedure Summary
The correction for this issue involves replacing all affected coolant changeover valves. The specific repair instructions vary depending on the number of valves present in the vehicle:
- If the vehicle has one coolant changeover valve, technicians should follow Repair Instruction 64 12 790, which details the replacement of coolant changeover valve 2 for the high-voltage battery.
- If the vehicle has more than one coolant changeover valve, technicians should follow Repair Instruction 17 61 625, also for replacing coolant changeover valve 2 for the high-voltage battery.
