What causes the engine to stall while driving in a BMW 6 Series?

I recently purchased a BMW 6 Series and have noticed that while driving, the engine sometimes stalls unexpectedly. It usually happens when the car is at a stop or slowing down. What could be causing this issue and how can I fix it?

One possible cause of engine stalling could be a faulty fuel pump. It's important to get this checked out by a professional mechanic and replaced if necessary. Other possible causes could include a clogged fuel filter or a malfunctioning ignition system.

Another common cause of engine stalling is a dirty or faulty Mass Airflow (MAF) sensor. This sensor measures the amount of air entering the engine and if it becomes dirty or damaged, it can cause incorrect readings leading to stalling. Try cleaning or replacing the MAF sensor to see if that solves the issue.
