One of the common causes of engine stalling in Audi A8 is a faulty fuel pump. It is responsible for delivering fuel to the engine and if it fails, the engine may shut off while driving. You can test the fuel pump by checking the fuel pressure and if it is low, then replacing the fuel pump would be necessary.

Another possible cause could be a clogged fuel filter. A dirty fuel filter can restrict the flow of fuel to the engine, leading to stalling. It is recommended to replace the fuel filter every 20,000-30,000 miles to avoid this issue.

A failing ignition coil or spark plugs can also cause engine stalling. These components are responsible for igniting the fuel in the engine and if they are not functioning properly, the engine may shut off. It is important to get these parts checked and replaced if necessary.
