ICV hose collapsing at idle

[Garageaholic]

At idle, the hose connecting the ICV to the intake manifold is actually folded... like the hose is too weak..

This is obviously not normal. I heard of getting a stiffer hose, but does this happen? I don't think the ICV is bad.

Has anybody had this in their 88+ E30?

I have had an ICV go out and the hose is rubber you should be able to just cut some scrap hose and make something fit I have had a lot of time at U-pull-it scraping car

Sorry to bump an old thread but does anyone have the part number for the hose that goes from the ICV to the manifold? Mine is having similar issues. I checked real oem and didnt see anything that resembled that hose.

I bought the aftermarket ones and like clockwork, had to replace them every year. After two tries I went with the original BMW one, the aftermarket(CRP) ones developed cracks and had me chasing vacuum leaks.

Part # 13411710793
