Today while driving I got the alert that the coolant was low.

As soon as this happened I turned on my mperformance steering wheel and noticed the following.

- oil temps were normal 220 normal mode 190f under m2 sport mode.

- water temp 220f under normal mode and 170f on m2 mode. While giving the engine load the water temps would go up. The highest I noticed was 235.

I also noticed the car wasn't providing heat into the cabin no matter the temperature I set it to. Center wheel near vent was set to heat/ red. Temps on HVAC were set to 84f. AC off.

I was only a couple mins from home. When i arrived I filled both tanks with bmw fluid that I had and distilled water with correct mix ration. 60/40. I couldn't locate a leak anywhere. I don't have any errors according to the bmw diagnostic window.

I've searched all over the Inter webs and can't find anything concrete. The car is a 19 M2C with 44k miles. Any have this issue ?

Perhaps this may be the problem

I found the issue. It's the driver side aux radiator seems to have a hole or something.
