Nice work trouble shooting and finding the issue bud

raise: now I have an idea of what to look for if my car starts acting up!!
My 530d had a pin hole on one of the water pipes to the water pump car started over heating at night on the highway.... couldnt see much and with the amount of coolant all over the belt etc thought it was for sure water pump....
I stressed my nutz off and got the car home next day checked everything found the pipe was ripped, replaced it bled the system and car is perfect...
So sometimes the smallest of things will give you such a panic you would think the worst of it
