Hello:

I own a 2008 Mercedes ML 320 CDI , and lately immediately after shutting off the truck a sneezing quality like sound comes from the mid portion of the engine (as if pressurized air is being released) followed by an electronic sound "vvvvvv" like sound ,similarly to a faulty computer fan.
I have attached a video. Any ideas?

I strongly suspect a problem with the EBOX cooling fan for the "vvvvvv" like electronic sound, which would be an easy fix, however, not sure if the sneezing quality type sound is related or not. Help!

Here if the youtube link of the video

ok, so I found the source of the sound and its this black box located in the picture.

I just need the name of this box and its contents.

Does anyone know?

Ive been searching online for the numbers and I cant seem to find anything.

Thank you !!

Not sure why, but mine sounds exactly the same. In fact my 06 E320 (straight 6) did the same noises.

The sound is normal.

Mine's done it since new.

I second that. All very normal. The black box is the glow plug control module, but behind it is the air intake mixer ducts where the EGR stuff meets the intake air.
