what could cause my BMW X5 G05 (2019-2024) to stall at traffic lights

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery cable to ensure safety while working on the vehicle.

2. Inspect and Clean Throttle Body

• Remove the air intake duct connected to the throttle body.
• Use throttle body cleaner and a soft cloth to clean any carbon deposits from the throttle plate.
• Reconnect the air intake duct securely.

3. Check and Replace Spark Plugs

• Remove the engine cover if necessary to access the spark plugs.
• Use a spark plug socket to remove the old spark plugs.
• Inspect the spark plugs for wear; replace them with OEM recommended spark plugs if necessary.
• Torque the new spark plugs to the manufacturer's specifications.

4. Inspect Fuel System

• Check fuel pressure using a fuel pressure gauge; replace the fuel filter if pressure is low.
• Inspect the fuel injectors for clogs or leaks; clean or replace as needed.

5. Verify Electrical System

• Test battery voltage using a multimeter; replace the battery if voltage is below 12.4 volts.
• Check the alternator output; ensure it is charging correctly (typically around 13.8 to 14.4 volts).
