Saw a new TSB concerning rough idle, this time caused by ECU hardware fault. (there is an existing one fixed by ECU SW reprogramming)

The Warranty repair is to replace the ECU with an updated ECU - part number 8T0997560BX.

Its worth knowing if you develop a rough idle and wonder if there is a fault - the TSB is for S5 only.

My car occasionally has some rough idling while at a stop. I'm glad there's a TSB to fix this. Will my dealer send me info on this or do I need to take something to them? Where did you find this information?

I just picked my car up from the dealership today from its 5,000 mile service. When I dropped it off, I told them about the rough idle I had occasionally experienced. They told me today that there was a software update relating to this problem, and they had updated my car. So in short, you should be able to just take it in to dealer with nothing in hand.
