The BMW X5 G05 (2019-2024) is experiencing symptoms of stalling at stops, indicating a potential issue with the engine management system or related components.

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before performing any maintenance.

Symptoms

•Engine stalling or hesitation when coming to a stop
•Rough idle while stationary
•Check engine light illuminated
•Decreased acceleration responsiveness
