What I find hard to believe is that some people here were driving their C32 like snail pace and they didn't realize until they did the ECU reset

Ad me to the list of Service Campain failures.
I have tried the ECU reset and it didn't fix the problem. I'm going to try it again today but I don't expect any success.
I have the same issues. Rough idle and at highway speeds I sometimes have a C230 sometimes it is the Autobahn rocket I bought.
Sorry about this being my first post.

I must add. It’s raining badly around here so I didn't get a chance to push it hard like I usually do. But at least the S/C wasn't shutting off after flooring it 3-4 times like it used to. I will try again once the rain is over and update everyone!!

I'm starting to think maybe its a coincidence that the pump is starting to die or a bad spark plug or something at the same time I did the recall.

Thank goodness I've found that I'm not alone with the rough idle problem. Been into dealers on four occasions now, and they haven't been able to replicate the fault.
Happens only when the engine is cold, 2 minutes in, and sat stationary waiting at the lights. Idle gets rough for 10 secs, and then smooths out again. When pulling away, throttle is hyper-sensitive and revs like mad before shifting to second. After that all is well again ...until the next morning!!
Dealer has already replaced the air injection relay, and will replace the air injection pump on Thursday. Not sure whether my car had the campaign update mentioned here or not.
Will try the ECU reset tomorrow to see if it makes a difference - sounds good even if it doesn't take away the rough idle!!
Will keep you all posted on progress

Got my car back yesterday. MB changed the I/C pump. After reading other threads apparently it's a common problem... Coincidence with the service campaign??? Maybe... I also did the ECU reset and the car is back to rocket mode.

The idle thing you guys are talking about IS normal, I have done PDIs on hundreds of AMG super charged motors, and when I first started doing them I spent 6 hours testing the stupid car all to find out from the super german tech specialist that it IS normal for amg motors to do that.
As for them messing up a vacuum line when doing that campaign it is pretty much impossible due to the fact the relay is no where near any vacuum lines, and the ecu programming takes place through the obdII connector....

Hey, this one is for those of you who have stated they are opting out of this recall. I've heard that, here in California, if you ignore a recall that is remotely related to the emissions system, the state will not allow you to register your vehicle next year, or until the recall work is completed.
Anyone out there heard of this in California or your state? Think it's true? I would love to say "no thanks" to this recall if possible.

well a vacuum leak that would cause that bad of a rough idle, would usually throw a check engine light for left or right bank adpatation values, it is possible that you could have a faulty plug wire. they could have screwed up on the reflash on the me-sfi you have to re flash and if the car calls for it scn code it, but mainly scn coding was only done to 05 and on cars I believe, other than that your shop would have to put the star on it and run a short test.

Now bear with me here...
My dealer has been looking at the engine for a cure, but I'm now wondering whether actually may be transmission. After the rough idle, when you pull away the engine seems to rev high and then shift, almost feels like driving in low-range in a 4x4 - lots of revs with little progress. Once this occurred to me, it dawned on me that the rough idle is a little (I said a little) like switching from normal to low-range on a 4x4 too.
Now I read somewhere that there are two reverse gear ratios on the AMG auto box. Maybe there are two cogs, or maybe a single cog with a multiplier cog somewhere that could also be applied to first when there is some kind of malfunction.
A long shot but this sort of explains both physical symptoms - rough idle and high-revs/little-progress. Whether there is any mileage in this thought is a different matter!!
Maybe I'm looking for an answer that isn't there to be found, and as has been pointed out all AMGs do this. Can't believe they would let it leave the factory like this though, as it very obviously feels like there's something wrong when it happens.
I'll get my coat...

Just took my car in to the dealer to have it checked. They said regarding the shaking problem, they checked the car and didn't find anything wrong and the computer didn't bring up any fault codes. Although, they did tell me my supercharger is bad. They said the supercharger could be falling apart internally. The way they diagnosed it was the excessive clatter it was making. They said the clatter is much louder than it should be and that they compared it to another car. The supercharger feels and sounds like its running and it seems like its been that noisy since I've had the car....there's so much clattering when i open the hood its kinda hard to tell. I guess I'll be using the extended warranty to get that replaced, he told me it is about $3400 with parts and labor to replace the supercharger. My service advisor told me the shaking is caused by the supercharger problem. There was no shaking before the recall.....I'm not sure if the supercharger problem is related to that, or maybe it was coincidence that it suddenly started to fail some more to cause some shaking. 
I'm have a feeling that if and after they replace the SC, its still going to shake!

For me, my car only shakes when my foot is still on the brake and the car is trying to pull away from stop (only on level ground). Just as my right foot is lifting up, but still have some pressure on the brake, that's when the car will start to shake. If I keep the brake in that position, the car will keep on shaking and inch very slowly forward, If I let go of the brake completely, the car would stop shaking and start pulling away smoothly. There is definitely one position in the brake that can cause car to shake.
This could be what Thrillhouse have described as "normal".
