How often do you guys take care of this? I recently went in for my first oil change at 9k, and for some reason, the car threw up a B6 code. Okay, fine. I got in, and everything seemed fine.

However, the dealership highly recommended changing the differential fluids. The front differential fluid costs $130, and the back differential fluid costs $170. I thought the oil needed to be flushed out, but not at 9k.

Any recommendations would be greatly appreciated.
