N63 Coolant drips under car AFTER a drive
N63 motor 114k miles. I got the low coolant light the other day and I topped it off and that day while the car was parked I noticed what I thought was water running down from under the car. I went to look and saw it was coolant. I topped a little off and yesterday noticed the same thing after a drive. A small pool forms under the car. It drips from the silver metal plate under the car very small drips like a water faucet.
I topped off the coolant this morning and drove it again and again it was dripping this time a bit more. I topped it off again this time both the tanks, under the engine cover and the coolant tank itself. Have not driven the car but not leaking now. Seems to only leak after a drive. I also notice sometimes steam coming out from the kidney grill and the AUX pump making all sorts of noises and weird sounds when the car is off after a drive. I looked and it seems it could be so many things so here is what I am going to do and wanted your guys suggestion and advice -Replace the AUX pump that makes noise -Replace the y connector coolant hoses under the car -Replace the leaking coolant hoses under the plastic engine cover -Replace the water pump?? Its so cheap right now might as well Anything else I should look/do I heard some sensor can also be a problem. - |

Coolant temp sensor on lower radiator is a common leaking point on bmws, I personally always replace the hose and sensor especially with higher miles like yours
