F15 N63TU Crankcase Ventilation Assembly Replacement Guide

[bmwx5_50i]

I appreciate the instructions on how to fix this. My 2014 50i hose just broke a few weeks ago. Neither the dealer nor BMW NA want to take it up under warranty. My extended warranty won't cover it either because it's a hose and those are explicitly excluded.

I get that they're in the market to make money, but at the same time they're losing customers with this. The fact that a 2014 650i with the same engine and same crappy hose is covered, but this model is not, is just stupid. I'm surprised no one has had an engine fire because of this.

I’d just like to add that a few of the fasteners were different than in the photos you showed. The screws shown in the 2nd photo were actually two torx screws and the one on the right was an external torx. For that one, I didn’t have the proper socket, but a regular 6mm (I think) socket did the trick. Also, that external torx couldn’t be removed on my car without first taking off a nearby electrical clip. I think the hardest part of the whole job was getting that clip off. It took me a while to figure out how to lever out the blue tab so it could be removed.

Same here, I needed a Torx 25, Torx 30, and Torx E8.

December bump for a great post. You can get both pieces, connecting hose and valve hose, for $218 total under the Motive8 brand on Amazon as mentioned somewhere above.

What exactly is the code that results from this leak?

I don’t think there would be one, as the hoses enter the intake after the MAF sensor.

No code. One of my connectors has been broke for years. Epoxied it twice and now just wrapped in electrical tape until I get the time to swap new how’s I’ve had for months now lol. Nothing catastrophic will happen. I jist wrapped mine to prevent any leaking oil which would be minimal at best.
