I know this has been done to death, quite rightly so - it's confusing.. however, every thread i've read, and all comments .. either are contradictory, or work ton the basis that P31 is facelift, and P30 is pre-facelift. My situation seems to be different to those explanations i have found.
I'm mid purchase (deposit paid) on a 2012 car (build date 04/2012).
Running the VIN through vindecoderz.com, i clearly get (amongst a huge list):
P30 - AMG PERFORMANCE PACKAGE
471 - MECHANICAL LOCKING DIFFERENTIAL
U70 - BRAKE CALIPERS PAINTED RED
540 - ROLLER BLIND, ELECTRIC, FOR REAR WINDOW
923 - OUTPUT INCREASE OF ENGINES
U47 - REAR SPOILER
From everything i've read, a 2012 car should be P31?
I've spoken to Mercedes, and they've confirmed in 'OASIS' (though sadly cant send to me..?!) on the phone that it has options:
P30 - "Performance Pack Plus"
471 - AMG Differential Lock
So .. all evidence points to P30, except the fact people claim 2012 car should be P31? and i read somewhere that 'Performance Pack Plus' is P31?
So.. My question.. What exactly is the difference between P30 and P31, and which do i have? (Does this car have the uprated internals?) You pay a slight premium for a 487BHP car with LSD vs cars without, so I want to ensure i'm paying the right price.
And secondly, i guess.. is 471 - 'Differential Lock' (aka 'Mechanical Locking Differential' on vindecoderz) actually Merc speak for a LSD?!
Many thanks! I can provide more info if it's of any use
