There are a few possible causes for this issue. One of the most common is a problem with the ignition coils, which can cause a misfire in the engine. Another possibility is a faulty fuel injector. It is also possible that there is an issue with the spark plugs, which could be causing an inconsistent spark. I would recommend taking your car to a certified mechanic who specializes in Audi vehicles for a proper diagnosis and repair.
