Since the trouble began so soon after it was serviced, I suggest taking it back in for a recheck. You mention that spark plugs were replaced. Your Audi’s symptoms could be caused by a poor connection at a spark plug or ignition coil.

If you would like a different technician to inspect and diagnose it, you may want to have one of the highly rated technicians from YourMechanic come check it out for you. They will be able to diagnose the loss of power and make the necessary repairs to get your car running normally again.
