A5 Rough Start

[MixedNutz]

I have had my 2011 A5 for a week, I noticed that if its hot and humid outside when I first start the car, it idles rough for about 5-10 seconds and the check engine light comes on. Its only happened twice.

This doesn't seem normal, but again I am a first time Audi owner.

What are the codes?

[MixedNutz]

I haven't run the codes. The light stays on for literally 3 seconds then the idle levels off and the engine light goes off.

Codes are diagnosis 101.

It could be spark plugs, coil packs, vac leak, carbon buildup, etc. If you want help you are going to need to post what engine you have at the very least.
