Australia Based, Performance Pack Question
I was thinking the same thing as the OP in terms of my 2011 C63 p31. I don't have a breakdown of the factory option codes but I was also wondering if my car has the LSD option as well. Mine's an Aussie delivered early 2011 (pre facelift/speedshift) and visually it comes with:
1. Red AMG (1.5/2 piece rotors);
2. 19 inch black multispoke rims with silver lip;
3. Carbon fibre rear spoiler;
4. Upgraded power & engine bits (back to back with a normal C63 mine feels a lot stronger);
5. Alcantara grips on the steering wheel; and
6. Stitched leather dash
Hard to tell if a diff is at work on the streets. Hard acceleration will still torture the rears causing the traction light to flicker.
Some pics of the car to see specification


Mine does it every day coming out of my driveway
My friends C63 (no LSD) doesnt do it.
Having seen some of the pictures of my car above, and being that mine is the last of the pre-facelift cars, is my car a P30/P31? I assumed p31 but possibly have just confused myself.
What I do know is that my car despite being stock is louder, stiffer and seemingly more powerful than a normal 63 so that indicates I have some form of performance pack from factory.
Sorry for all the noob questions and detracting from OP's post/thread.

t4orce - don't forget the Titanium Grey intake manifold in the P31 package.

P30 is no longer available.
923 -output increase of engine
p30 - AMG Performance Package
U47 - spoiler lip (carbon I assume)
U70 - brake calipers painted red
So according to the datacard, mine is a p30 with increased engine output (of p31?). No mention of a diff but some here say that it comes standard with p30 and others say that a diff is confirmed by 471 code which I do not have.
You can see why I am confused?!? Only way now is to track test!

My 2010 C63 with P31 referred to as AMG Performance Package on my window sticker and as the AMG P31 Development Package by MB USA. I recorded the P31 Option list available on the US AMG site at that time. The Limited Slip Differential Lock was listed as a separate item on my window sticker which is not too surprising since it was a stand alone option and not included in the AMG Performance Package for 2010.
AMG P31 Development Package
-Lightweight AMG forged pistons
-Lightweight connecting rods
-Revised crankshaft
-Revised ECU
-Red-painted brake calipers
-Carbon fiber trunk spoiler
-Exclusive engine intake runners in titanium grey finish
-Top speed increased to 174 mph
-Power increase (+30 hp)
-AMG performance steering wheel in black premium leather with Alcantara side grips
-AMG high performance braking system with compound front rotors:14.2 inch compound construction brake rotors with 6-piston fixed calipers at the front axle,perforated and internally ventilated for optimum weight and enhanced fatigue strength.
t4orce I agree with whoover and don't think the LSD is included in your car and think the 471 option code needs to be listed separately.

As far as I know, the modified suspension was uniquely P30 and when it was deleted the factory stopped using the P30 code. That's true in North America and Europe but I admit I'm not sure what it means on face-lifted Australian (and Canadian?) cars.
Luckily, everything is listed as a separate code item so you can know for sure what any given car has.
However, does that make my car a P30/P31 or a hybrid of both? The datacard suggests P30 which includes the stiffer suspension and braking package. I also have the increased engine output option. Does that mean the SLS internals giving rise to the 30+hp increase?
If so, then I guess the 2011 Australian performance pack cars are a hybrid of P30/P31 with LSD being an option to both packages.
