my BMW 5 Series G30/G31 (2017-2024) keeps stalling, what could be the issue?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to prevent electrical shorts.
• Allow the engine to cool before beginning work.

2. Address Fuel System Issues

• Fuel Pump Replacement:
  • Remove the rear seat or access panel to reach the fuel pump.
  • Disconnect the electrical connector and fuel lines (use caution as fuel may spill).
  • Unbolt and replace the fuel pump with a new unit.
  • Reconnect the lines and electrical connector, ensuring a secure fit.

3. Clean or Replace the Throttle Body

• Remove the intake ducting leading to the throttle body.
• Use throttle body cleaner and a soft cloth to clean the throttle plate and housing.
• If damaged, replace the throttle body by unbolting it from the intake manifold and installing a new one.

4. Inspect and Replace Ignition Components

• Remove the engine cover to access the ignition coils.
• Use a spark plug socket to remove the spark plugs; inspect for wear and damage.
• Replace worn spark plugs and ignition coils if necessary.
• Reassemble the ignition components and cover.

5. Replace Air Filter

• Open the air filter housing and remove the old air filter.
• Install a new air filter, ensuring it fits snugly in place.
