Hi guys - 2013 135i DCT with a little over 11k miles, low coolant light came on so I go to check the coolant level. Other threads as well as my owner's manual show there should be a floating stick inside the coolant reservoir to measure the level, however there is definitely nothing inside mine other than a (fixed in-place) small plastic yellow circle with min/max on it. I'm assuming I just fill to the top of the yellow marker, but the fact that my owner's manual shows a floating dipstick of some sort makes me worried. Like I said only 11k miles on the car so this is the first time the reservoir has been opened. Is this normal on the n55s? Took almost a full quart of coolant / 50-50 distilled water to bring it up to the yellow circle.
This is after I had already added almost a full quart:
