Coolant leak... where?
So after I finished all the trouble of diagnosing and fixing the engine stuttering I have now come to a new problem... coolant leak lol...
The coolant is dripping by the passenger side... I tried looking for the usual signs, bleeding screw, radiator cap... replaced both and it's still leaking... The car is not overheating, the fan is not always on, so I don't think it's the water pump... what can it be?? Any usual N55 leaks? Any help will be appreciated

Just to add... whenever I fill up the tank and run the bleeding procedure I don't see any leaks... however, once the car has come to temperature that's where I see the leak.

I went ahead and ordered one either way... if the leak is not persistent all the time then I can remove the possibility of a hose... if the leak starts once the car comes to temperature then there's a chance that the reservoir has a leak somewhere... crossing fingers!

Very hard to say from photos, as a lot of coolant lines over there. as well as the waterpump.

Hate to say, but that looks like the hose going to the Waterpump. Concerned the waterpump gasket may be cracked or gasket leaking = $$$ Hopefully you can just tighten the hose clamps? https://www.realoem.com/bmw/enUS/par...-X1_35iX&mg=11 https://www.realoem.com/bmw/enUS/sho...diagId=11_4468

I finally had some time to check this out and it turned out to be the water pump that was leaking... I went ahead and replaced the thermostat as well
