Hello all...

Just completed a charge pipe and IC (both from Active Autowerke) install on my 2018/LCI (6MT). There is a hose connected to a bung on the side of the charge pipe near the throttle body, it connects to some sort of sensor that is just kind of floating above the intake manifold, and then it also connects to the intake pipe just after the MAF/MAP.

I managed to break 2 of the 3 connectors trying to get them unplugged. The plastic was super brittle.

I'm pretty sure this is all vacuum-related stuff? But I can't find a diagram for any of it on RealOEM, so I can't find part number(s) to replace the stuff I've broken.

The "hose" has the clips on the hose itself at the intake pipe and charge pipe, but where it connects to this other sensor, the clips are part of the sensor, I think... so I'm guessing this is going to be more than a $10-25 mistake to repair.

Everything seems to be holding together OK for now, but I want to fix it correctly with new parts.

I think everyone jacks that hose up getting it off. Mine broke on one side but is holding fine. I bought another one just in case I have issues in the future. I think this is the one.

yeah, mine has more going on than that... it has 3 different connection spots. But i'll check out that website maybe they have better parts diagrams than realoem.com does

Part number 10 on this diagram (Which I haven't found the p/n for yet) is the main thing that was a PITA.

But one of the clips is actually on part 7, so I feel like that has to be replaced as well. Why the hell they couldn't put the clips on the hose for every connection is beyond me.

Part #7 is:
Fuel Tank Vent Valve - BMW (13-90-7-636-156) - I assume this takes vapor from the charcoal canister and spits it back into the intake tract for combustion... yay emissions nonsense.

Here we go, found it on RealOEM now that I know it's related to fuel ventilation junk.



Part number 4 is the same as 7 from the other one. Part number 7 on this diagram is the hose itself.

For posterity: part #4 on the diagram is: "Fuel tank ventilation valve with pipe", p/n 13907636156

Part number 7 is: "Sucking jet pump with lines", p/n 13907604938.

It is highly likely that you break the plugs on each of these connections when trying to remove them. And BMW are a bag of assholes and rather than putting all of the couplers on the cheap hose piece, they put some of the fragile locking parts on the more expensive "valve with pipe".

I was thinking I could get away with just replacing 4 and 7, but I suspect something on part 5, "fuel tank breather line", p/n 13908602280 will break while doing the other two parts...
