2007 X5 4.8 overheating, cooling fluid lost

Hi there. Today I was sitting in my BMW X5 and the engine was running in idle. After 20 min I heard a noise coming from the engine area and steam start developing under the hood. I turned off the engine right away and opened the hood. There I had to see that the cooling fluid is running out somewhere at the bottom front of the engine. Now I am wondering. Is there a safety valve which releases the fluid by to much pressure caused by overheating? Or do I need to get a tow truck?

Hello, sorry to hear that. Unfortunately this happened to me as well (but I was in the middle of a trip and at a rest stop with the engine at idle), but I could add coolant and it would last about 30 miles or so, then the light came back on. It was replaced under warranty...information in quotes was taken off the repair order:
"Found coolant hose running between both heads & upper radiator hose leaking" "Installed 17 12 7 536 236 :SA-Vent Pipe" "Installed 07 12 9 952 104 - Hose Clamp"

Not saying it is the same thing as yours, but it might be. Good luck

Get it towed, do not restart it. BMW's do not tolerate being driven in low coolant conditions, that's when replacement of a cheap plastic cooling part turn to engine failure faster than you realize. I believe your engine (N62) will shut itself off to prevent engine damage, but I certainly would not test it on my own car.

Ok. I found out what the problem is. My reservoir tank for the cooling fluid is cracked. I don't know how this could happen. Cause I always sought there is pressure in the cooling system and this looks like it got sucked in.... i will try to post a picture

All plastic cooling system parts fail with time and or miles - usually one after the other. The expansion tank, thermostat and radiator side tanks are common plastic parts with high failure rate starting around 90k miles on some BMW models. The water pumps used to be a problem as well, but I think the one in the N62 holds up better than previous generations.
