HI, my buddy has a 15 GLA45 and his rear diff just started chattering. Looks like he needs a fluid change. He has only had it for 6 months or so and got it used. I looked up the procedure on Alldata and it says you need the M-B diagnostic tool to do all these resets and relearn procedures after changing the fluid. Is there a way to do this without taking it to the dealer and do it properly? I have a shop with a lift and can do the fluid change, no problem. Im just concerned that these resets and relearning need to be done also. Thanks.
