I have a 2008 535i. When driving today I got a coolant level low message. Pulled over right away and checked the levels and it all looked normal. No dripping or signs of a leak or high temps at all.

When I got to where I was going and shut the car off, the engine bay started smoking and a huge amount of coolant came pouring out on the passenger side of the engine bay.

The exact same thing happened after driving it home. (I know I probably shouldn't have drove it but whatever.) Still no overheating though on my way home.

I can't find anything about a similar issue anywhere on the internet so I was hoping maybe someone here could help.

Thanks!
