How to troubleshoot engine stalling issues in the Audi A6?

I've been experiencing unexpected engine stalling in my Audi A6. It mostly happens at low speeds, and the check engine light comes on. What could be the cause of this issue and how can it be resolved?

The most common cause of engine stalling in the Audi A6 is a faulty fuel pump. Have it checked and replaced if necessary. Additionally, check all electrical connections and clean the throttle body to ensure proper fuel and air flow.
