Hi folks, i tried searching and couldn't find an answer. We currently have a P85D that we regularly service. Shortly after that purchase we also bought a used 85D with a few thousand miles on it at the time to use for road trips (so we avoid putting too many miles on P85D. currently already at 50k). However for this 85D, we have not done ANY service / maintenance on it through TESLA. It's sort of our "second child" and doesn't get all the love the P85D gets . Reflecting back, I feel like it was a waste of $$$ to even get the P85D serviced at all. I should have done what I did with the 85D basically doing the needed work myself. i.e. keyfob battery replacement, wiper blade change, cabin filter, etc. 85D has 48k miles now, so the only thing I am worried about is the battery coolant and the brake fluid replacement as part of 50k schedule. Any recommendation on what I do? is the battery coolant and brake fluid really required at 48k? the 85D is about 2 years old. do folks take their cars elsewhere for this? Does tesla just do work on brake / battery fluids? coming from a long list of BMWs and having pride in doing things like brake jobs, oil changes, engine mods myself, I cannot make myself spend $850 for coolant and fluid change!
