After some research, I've found the codes in my warranty booklet do not match the actual equipment on my car. Most glaring example is I have a manual trans (usually code M6S) and mine says A7S (auto 7 speed). Verified codes on the spare tire well. The sport diff code (which I know I have) has the part reference for the auto trans diff. Anyone else have this type of discrepancy? I bought the car used from Carmax 2 years ago with 22k miles and it's been trouble free, so I don't suspect any fraud.
