This is normal. The MAX line is a service line for cold. As long as it's above the MIN and close to the MAX line, you'll be fine. With the fluid so close to the MAX line, you have nothing to worry about. It's not that sensitive where you're going to hurt anything. Service everything to the MAX line cold and you'll be fine. (You're perfectly fine as it sits right now, as well.)Why would the main one read near Min and the others over Max? Engine is cold.
Mine is a 2020 2.0t JLU Sport also has a black tank. This is the most annoying design ever. You have to unscrew the cap and use the dipstick built into the cap to check level. I seem to need to top off with about half a cup of coolant a month but cannot find a leak. Not sure if this is a problem or not. Is this amount of coolant loss OK?Riddle me this one, Ours is a 2022 and the engine coolant recovery tank is black and you can't see the level. The other reserviors are clear???
