x3 e83 coolant leak

[dynopower]

Hello all,

I am a new X3 owner and I have a little trouble identifying the broken oring/piece I need to replace in order to fix my big coolant leak. I attached a photo where you can clearly see the T-piece that is leaking. I can see one end being connected to a plastic coolant tube, one end going to an oil-coolant heat exchanger, and one going apparently somewhere towards the engine. My leak is at the plastic connection. I tried realoem and I came pretty close but I cannot find exactly the T-piece. If someone could help me that would be great. Thank you very much!

Best regards,
Florin Tufescu

What year is your X3?

I can't believe I forgot to mention this, sorry It's a 2004 3.0d, I think the engine code is M57N. Also I suppose it's relevant to mention that it has an automatic transmission.
