You're positive it's not a vacuum hose? I would be surprised.

Does the car run?

Any pics here look familiar?

Mine is nothing like any pic in this link, most properly it's not the vacuum line/hole. Thanks.

"I cannot see down there" is not the same as "it should no go down there.

Take a look at these two.

Thank you for helping me out. I found something similar to your images but mine already has the rubber holes in places.

Deroy, you had pointed me to the right direction. After the intake pipe was removed, I was able to to see the 1 open port to reconnect the the vacuum line(?). The problem is I cannot insert and secure the line. I don't know if something is missing from the vacuum line or from the open port?

 

[dustinN]

In your diagram, by the first red arrow, next to number 16, there are 2 ports, the one on the right has the tip sticks out to insert the vacuum line. None on mine, maybe it was broken and felt off already? I have to replace the hove valve cover???

I use some wires to tight it with other lines trying to keep it in place. Good thing, CEL has gone, I can floor it to test, up to 6000 rpm for a few seconds without any issue. I could not go over 3000 rpm and got error message "Engine Malfunction. Power reduced" before reconnected the line. Now everything is clear. Thank you so much guys!!!

 

[deroy]

Thanks for closing out. Glad it all works now.

How often exactly did you say it was NOT a vacuum hose ?

Anyway. That tip you mentioned, now that I look at it again, is a plug to plug the hole for some vacuum testing procedure I took the pic from. The hose should go in its place. Good thing is that once there is some vacuum, the hose sucks itself in place. In theory at least.

I know I am sorry. I removed the cover but did not see the port. Until I removed the air intake, I saw 1 open port, everything you said started to make sense.

Thank you for info about the hose sucks itself in place. This make me feel less worry about the hose get disconnected again. Thank you so much!!!

Glad to hear it sucks?

I did not see those either. Guess what, I never even saw an n54 engine in person. But the good thing about newTIS, realOEM, part numbers and google image search, and some car knowledge, is that you can see things before seeing them yourself.

just googling it, looks like a MAP sensor code. Manifold absolute pressure.

It does NOT (necessarily) mean the sensor is bad. Could be, but could be other things.

There are a TON of posts and threads about many different BMWs with this code and similar engines....

How does that loose hose trigger that code? Can we now explain that? Too much pressure by wastegate not opening?
