How to fix my Audi A4's inconsistent engine performance?

I've noticed that my Audi A4 has been exhibiting inconsistent engine performance recently. It seems to struggle with acceleration and there are occasional jerks while driving. What could be causing this issue and how can I fix it?

It sounds like your car may be experiencing misfires, which can be caused by various things such as faulty spark plugs or a clogged fuel filter. I would recommend taking it to a mechanic for diagnostic testing and repairs.

Have you checked your car's air intake system? Sometimes a dirty or clogged air filter can affect engine performance. I would suggest getting the air filter replaced and see if that makes a difference.

I had a similar issue with my Audi A4 and it turned out to be a malfunctioning engine control module. I would suggest getting it checked and, if necessary, replaced by a certified technician.
