New Oil Separator Q: Wire Harness Box

Hey everyone,

In doing the OS DIY, I can't get the wire harness box out of the way. All the wires going into the box aren't held on by any fasteners (they're just going entirely into the box itself) and in order to move the box out of the way, I have to disconnect a ton of wires (that actually have fasteners) that aren't exactly easy to get to (which doesn't seem in line with all of the DIYs out there).

If it matters my 330Ci was built in July 2002, so it's possible things could be different with the wire harness box.

Sorry this post is for those people who have probably completed this DIY already.

Thanks for any help/suggestions.

BW

if you remove the oil dipstick tube, then you can pull that whole box out of the way. there are 2 torx screws holding it to the intake manifold

Yeah, I actually have EVERYTHING out of the way (dipstick guide tube is out, so is DISA, ICV, throttle body) except this box. There are literally too many connections coming out of it and I can't disconnect them all.

I'll see if I can get a pic and show you. Even the wire harness box in the Bentley manual doesn't look the same....

you dont actually remove the box. you just pull it over towards the drivers fender. if you go on youtube there are videos of the entire process. actually here you go:


thats the first of like 3 videos. the others come up at the bottom of the screen at the end of the video. hope this helps

Alright, some pics of what my wire harness box looks like. It seems to be longer than most with just a TON of connections coming out of it.

I have a feeling I'm going to need to remove the intake, but oh well.

If you have an M54 engine with the following wire harness box and you've found a convenient way to move this thing out of the way, let me know.

I'm just dealing with the extremely limited space, and have the OS out, about to put the new (cold-weather) one in...

Thanks for trying to help me out ... I'm just dumb sometimes
