I guess, after research, I will take the R350 to the dealership and have them change the fluid. I hate the fact that I will not be able to do it myself because it looks like a fairly simple process. You just need the special pump to get the fluid in.
I don't trust the dealership to do this job any better than myself. I have had arguments with the parts department for giving me the wrong hydraulic fluid before for my 99 e320 wagon. I just hope the dealership is as competent as the members of this forum. To further make my point, the "service managers" at the local dealership are young females who don't know squat about automobiles.
