Why does my Audi A6 have a rough idle at low speed?

I've noticed that my Audi A6 has a rough idle when driving at low speeds, especially when starting from a complete stop. How can I fix this issue and improve the overall performance of my car?

This rough idle could be caused by a number of things, such as dirty fuel injectors or a clogged air filter. Try cleaning these components and see if it improves the idle. If not, it could also be a sign of a more serious engine problem, in which case I recommend taking your car to a certified mechanic for further diagnosis.

Another common cause of rough idle in Audi A6 cars is a faulty spark plug or ignition coil. These components should be checked and replaced if necessary to ensure smooth and efficient engine operation.
