So the amazing guys at Unplugged Performance in Hawthorne, CA installed some moderate lowering springs a couple weeks ago on my M3LR. They mentioned they saw some dirt buildup of what looked like a leak from the front drive unit and that I should get Tesla service to take a look. Well, I did that today at the Seaside, CA Tesla service center. They told me that they couldn't find any evidence of a leak and that it was simply dirty from normal AC condensation. Attached is the photo that unplugged took. Any thoughts? To me, this looks like an accumulation of dirt from an "oily" substance, not water. Thanks in advance.
