I don't remember any Chrysler tech ever being specific about any service on the XFire. If you need specifics on Service A & B, I posted a while back what the differences are. The oil is 0/40 Mobil 1 Synthetic. The oil filter is that of the SLK 320 other than that service B just adds the replacement of the in cabin pollen filter replacement and just checking of everything else like alignment, brake pads, ball joints, tires, belt, wiper blade check but not replacement for that they charge (something you can do yourself) and the lubing, (again something you can do at home) of the door, trunk and rear wing hinge mechanisms. That's pretty much it. If you need more specifics please advise there isn't much that is required unless you detect something really out of the norm that needs further looking into, at which point i would advise you taking in to service.
