Could be a carbon build up symptom. Had that done at all?

[NavajoS5]

I was thinking that but hadn't thrown a code for that, no matter what we did its always cylinder 2. The car is perfectly fine until 3rd gear going over 3-4k rpm.

The only things that really caused that on the DI BMWs I'm more familiar with were injectors, coil packs and carbon build up. Most did what you did- plugs, coil pack. If that didn't do it next was usually injectors then carbon cleaning depending on mileage. Given you have around 66k miles, it's a fair bet you have a carbon problem if the injectors aren't known to fail.

Any rough starting when cold?

[NavajoS5]

Cold starts are fine. I'm sitting on 70k now put on 20k Highway mileage this year. Car runs great other than not being able to race ppl, I have to drive civilized. And can easily cruide around 100mph. Fuel injector was my last choice but dammit Audi had to put it internal? Isn't that like a $2k job

I'm gonna say that you need to change out the coil pack connector. I am in the middle of doing that to all eight of my connectors and it is fixing my miss fire issues. If you're connector isn't making a click when you plug them into the coil pack then you aren't making a good connection. Heck even the one that I did have click still wasn't making a good connection.

You can buy replacement plugs with pigtails installed already from eBay. Part # 1J0973724.

If it looks like this in your plug them I would change it. It should look like the second pic.

Yeah 1 and 2 won't click in but it looked good enough lol. That was the same issue I had fixing the airbox solenoid. Plug wouldn't click in anymore.

Haha, I thought so too. I almost replaced all my coil packs until I noticed that they were already changed out for the red R8 ones, so I figured I would try the connectors first since I've read that they can become an issue if unclipped/clipped too much.

[NavajoS5]

Let me know if it works
