BMW 535i xDrive battery replacement warning after fully charged, stalling in stop and go traffic on BMW 535i xDrive

Some BMW 535i xDrive owners report experiencing battery replacement warnings, such as "Battery discharging while stopped" and "Battery heavily discharged," which may indicate issues with the battery or charging system. These warnings can occur after fully charging the battery and may be accompanied by stalling in stop-and-go traffic, potentially linked to a failing battery or alternator. Owners with batteries older than six years often encounter problems with charge retention, triggering these warning messages. Additionally, modifications to the vehicle, like installing PPF, may lead to false battery replacement alerts due to software glitches. To address these concerns, it is advisable for owners to have the electrical system professionally checked, replace aging batteries, and monitor for parasitic battery drain to ensure optimal performance. If software issues are suspected, clearing messages in Diagnostic Mode or consulting a qualified technician may be necessary.
