What is the most common cause of engine stalling in the Audi A6?

I've been experiencing frequent engine stalling in my Audi A6, what could be causing this issue?

One of the most common causes of engine stalling in the Audi A6 is a faulty mass airflow sensor. It is responsible for measuring the amount of air entering the engine and adjusting the fuel mixture accordingly. If it is malfunctioning, it can cause the engine to stall.

Another possible cause could be a clogged fuel filter. When the fuel filter becomes clogged, it restricts the flow of fuel to the engine, causing it to stall. It's important to have the fuel filter replaced at the recommended intervals to avoid this issue.
