bubbles-like sound from the dashboard front passenger side
I am driving a 1998 E 280, 6 cylinders, 230,000 kilometers, in a very good condition.
One issue that I am having is that every now and then, I hear a sound, bubbles-like; my best guess to the location is that its coming from the engine side, behind the dshboard at the front passenger side, or may be from the dashboard itself; can't really tell. I hear it sometimes once a month and sometimes every two weeks and sometimes it does not come at all for 3 months. Actually I have no clue what it is or what it might be.
One guy told me once, it might be the water pump!!
Can anyone please help?!

Thanks,
Sameh
