E 350 2006- Iridium Silver with charcoal interior,premium package
sbc question
have a 2006 E 350 and have gone through the usual getting used to sbc noises-including the wake up, grinding of the pump and clicking which is fine- i am very happy with the brakes so far
my question is that about once a day -when i get home and park the car in the garage and return to open the door -about 5 minutes later- i hear a series of sounds from the engine compartment- best described like "the sound of some ice cubes falling down in the ice maker compartment of a refrigerator"- now it only occurs one time a day and that is it.
i spoke to a knowledgeable service manager who stated that it was the sound of the system releasing pressure in the valves of the braking system and that every car would do this at a different time depending on when it thinks pressure is to be relieved-eg at the end of the day
what do other members think of this sound and have others heard it
thanks

Yep, startled me too when I first heard it. Asked my SA the last time the car was in for service and he said "It's the SBC system getting ready for your crazy *** driving."
It's normal, don't worry.

thanx
but is it the sound i described-ie in addition to the relay type sound and the occasional pump grinding-this is more of a pressure release sound-
