hi just wondered if i could pick your brains, i have found one of the plastic vacuum pipes off from the black box under the pollen filter on the right side of the engine bay. it has two pipes coming off it one connected the other just lying roung the back of the engine. could someone tell me what the box does and maybe what the other ends connect to.
cheers
