Coolant leak
My 2001 C320 have developed a coolant leak (loosing coolant).
Over the weekend I did try to investigate any "known problems", but didn't notice any leaks around engine (no signs of water on the under engine plastic panel either)
However, I noticed a puddle of water on ground near mid section of the car behind transmission. I initially thought that it just could be condensation water from the A/C. Just to be sure, I did start the engine and turned heat on and after awhile it started dripping again. So I lifted the car up and noticed that water is coming from the condensation drain vent/pipe (at least I think that they are, see picture below). There are small maybe 1/2inch pipes on both side of drive shaft "channel" behind transmission (there is a cross member right under them).
In absence of any other obvious leak(s), my guess is that my heater core or plumbing around it is leaking. I am assuming that the condensation drain pan is also under heater element, thus is catching water...
Do you have any other suggestions/ideas what to look for? Getting to the heater element seems to be quite task.....

PS. I seem to have a Behr radiator, but plan on checking transmission fluid for water too....just to be sure

Final Correction
Hello, did you ever figure this out? I have the same issue right now- I can not find the leak, its not coming from front of engine (water pump, radiator, inlet/outlet hoses, nothing). It seems to be leaking from mentioned cross member under transmission- right where the transmission mount is. Did you fix it? Any pictures or instructions? Thanks in advance.
