I have a 2015 S 85D. I’ve noticed on some trips over the last few months that SC has limited charging to 32-35KW. I’ve also been kicked off a SC after a few minutes with the “check power source” message. When I get back to the car it reads service required and car may not start. Never have problems with home charging. Any suggestions appreciated! This makes road trips not so fun and kind of stressful!
