Your pics above show the s4 carrier but you dont have them on your a4.
The carriers on your a4 look identical except they're smaller.

I see, so I took a look at the calipers and looks like the 2 bolts you guy are talking about on my car are 19(it says 19 on them) regular bolts with a rubber boot under.
One more question about the brake pad sensors.
As I understand only the front has one sensor each on the inner pad. So if I carefully unplug them just to check the pads if they wear evenly and to clean the inside of the caliper I shouldn't have any problems right?

Only the front left has a sensor and yes, you can reuse it. Be careful to remember where the spring clip goes. I got that wrong and broke the sensor. The picture on ecs tuning shows where it needs to be.

[QUOTE=Rissen IK;24503180]You guys talking about this 2 bolts?
If yes whats the tool called and size?
So is there a socket avaliable for this bolt? I want to change the rotors on my 2014 A4 s-line. It looks like I need to remove these bolts to replace the rotos. Is that correct? I have never seen a bolt like this before, I found a socket for an S-5 on Amazon but it is to small for these. Thanks for your help guys.

Those bolts in that picture, the service manual is repeatedly adamant about "DO NOT TOUCH". Do not touch those bolts.

To remove the rotor, you need to dismount the caliper carrier, which is held to the wheel hub by two bolts. ETKA designates these bolts as replace if removed, and it sucks as they are $6 or $7 a pop, at least for the 2009.
They are on the backside of the carrier, and are torqued to a high value. But my documents are for a 2009 US A4. You'll need to get your model's documents from erwin.audiusa.com (pay for a day, download the relevant PDFs).

Thanks for the guidance guys, Changed them out today. Other that the rotors being a bit stuborn to pull off everything went smooth. about 20 minutes a side.

You'd have to measure your bolts to see what size they are, but google search tends to work well. I just put in "10 point bit" and here's one of the first hits: It's a M14 (14mm pt to pt). Not sure if other sizes are out there; market seems to be "tuner lug nuts".
