02 745i - Gurgling sound from engine

When the car is at idle I'm hearing a gurgling sound from the front engine. Anyone have any experience with this, or maybe hear anything related?

Best Regards,

I don't know if this will help but my past experience with beemers is when you hear that sound you may have air in the radiator system trying to get out. you may need to have the system bled and check water pump and thermostat to see if that helps.

and we also need pics of yout car, OP!

i had the same sound coming from my engine, but it sounded like it was more related to the a/c. anyways, i had my primary blower resistor replaced as well as the blower motor and the sound is gone. it can be either one. the reason i replaced these two things is a long story.
hope this helps in ur search of this mysterious sound.

I have the same sound coming from mine when i was under warranty i told dealer and they said they bleed system but that didnt fix it let me know if you get it resolved.
