I own a 2005 325ci that leaks power steering fluid so I put a tray under my car at night so it doesn’t get on the driveway. This morning however, I noticed the pan seemed full of liquid. I pull out the tray and there’s a MASSIVE amount of blue-greenish liquid in the pan (picture below). What could be the cause of leaking THAT much liquid at once? The coolant light turned on for the first time the previous day, but there were no signs of liquid leaking. I greatly appreciate any help that I may receive, thank you.
