Hi,

I have a 2009 R55 Clubman S. Noticed a small oil drip or coolant, on my driveway and traced it to this part (red square). Not sure what it is called or what the hose is called (black square). Seems like the hose is rotted where it connects to the part and the oil or coolant is leaking at the bend onto the wire that go to the oxygen sensor.


Thanks for any help!

 

That’s the electric coolant pump for the turbo. Pumps coolant after shut down to cool down the turbo.

 

Thanks for the information! Appreciate it!
