TL;DR: My car's charger broke and they replaced it under warranty with an ECU that is CCS enabled.
A few weeks ago I went out to the garage to drive to work, and found out that my 2021 Model 3 hadn't charged overnight. I was getting a "Charging equipment not ready" error on the screen, and my Grizzl-E wall charger was flashing an error code saying it encountered a "diode fault" (9 red flashes). Because of the Grizzl-E error I thought the problem was my wall charger at first, but my Tesla mobile charger was throwing the same "Charging equipment not ready" error in the car (using multiple outlets). I suspected it was a problem with the car at that point. I managed to barely make it to a SuperCharger, which charged the car no problem. So I figured the source of the error was the A/C converter on the car's on-board charger and made a service appointment through the Tesla app.
I had to rely solely on Supercharging for 2-3 weeks until my appointment, topping up my battery every 1-2 days. A bit of a hassle, but luckily there's a Supercharger fairly close to my workplace. This would've really sucked if I lived in an area without Superchargers.
Fast forward to my service center appointment. Tesla had already diagnosed my problem remotely and had the part ready to install. I had a two-hour wait and the car was fixed. No cost to me because it's under warranty. When I checked my invoice, I noticed the part number for the newly installed ECU (1537264-00-B), and googled it to find out if it's CSS enabled. My original ECU was not, and stated "Not Installed" in the CCS section of the software screen. But now it says "Enabled." I was going to have to upgrade that part anyway once Tesla releases a CCS adapter in the US, maybe at my own expense. But since my ECU crapped out, it's already done, and done for free. my minor hassle turned out to be a blessing in disguise.
One side note...I submitted a trouble ticket with Grizzl-E tech support when this first happened. It took two weeks for them to reply, which was disappointing. In their defense, they offered to replace my Grizzl-E, but by that time my car was fixed and I knew the Grizzl-E wasn't at fault. So not a major black eye to the Grizzl-E folks, but I certainly expected a quicker response to my trouble ticket, especially since I chose their product due to their North American location.
