Today I was going to change my sparks plugs so I had to remove my engine cover in order to do so (duh). Anyways, when lifting my engine cover off I found a mechanical box with some hoses attached to the side of it, directly behind the oil cover. What is it? and how do I remove it?

Can we get a closer non upside down pic? Maybe circle it

Sorry I didn't have access to a computer at the time so I was attempting to upload the picture from my phone. I've updated the original post with proper pictures. Thanks

I just posted about this yesterday in the spark plug change DIY video thread. Seems like the early F30s have it. They're vacuum hoses of some sort. Not sure of the exact function (the Bentley manual doesn't even mention it). Maybe later models have the same box, but not mounted to the underside of the engine cover? Anyway, just squeeze the notched part of them and they pull right off. If you can't squeeze hard enough with your fingers, try needle nose pliers (but carefully!).

I know this is an old thread, but I didn't want to make a new one.....the circled part. Does anyone have the official name and/or a part number for it? This is missing on my engine cover and I need to get it replaced. Thank you.

Also, I am guessing the back hose attaches to the vacuum pump in the back? Where does the front hose connect?

As far as I know the part that is circled is attached to the engine cover and cannot be bought separately from the dealer.. You can likely find one from a wrecker and simply detach it from the engine cover or if the engine cover from the wrecker is in good shape just use it.. The nipple towards the back attaches to the hose that is connected to the vacuum pump and the nipple towards the front attaches to the boost solenoid.. I hope this helps!!

It did help. Upon further investigation I've learned my wastegate is electronic so I never had or needed that container. I just have a bad vacuum pump (or seal). No hoses or containers missing.

You are correct if you have the electronic wastegate. The above system is only for vacuum operated wastegates.

My daughter got her il changed at one of the usual places and then starting losing oil. Turns out these small hoses were not re-connected. Not sure why they do, but, you will lose oil if not re-connected.

Why would they have been disconnected to change the oil?
