Did you recently fill up with gas? You may have gotten a bad tank of gas. Had that happen on my S4. Fresh gas from a different place - problem solved. Hopefully that's the easy fix!

Is your gas filler cap securely fitted? Could be drawing in air if not "clicked" properly.

First, your throttle stop may be not be normalized. From the car being off, insert the key and urn your ignition key to position 2 and wait at least 90 seconds (without starting the car). I usually wait two minutes. See if this helps. Usually the throttle stop not being normalized can cause wandering idle, not rough idle. If this doesn't help, then...
Ask the dealership to perform a flywheel adaptation. The ME settings (such as phase of spark timing) can be out if the battery goes dead or from other situations.
