Broken corrugated tube on inlet pipe

dbatech99 · 01-18-2024, 06:37 PM

Help. Put new spark plugs and ignition coils in the n55 today. Was super careful, but still broke this POS corrugated tube in the inlet tube. BMW engineering 😆.
Could somebody please tell me what it is called and how hard it is to find a replacement? Probably just have to replace the whole part whatever it is. Attached to the intake tube coming off the turbo.

I'm new to this car.

Thank you so much!

It is called Crank case vent hose, part #11127584128. Don't feel bad. It happens most of time. Hose is very brittle due thermal cycles.

Get one on eBay is much cheaper.

^This^ and it is a very common item to break when doing plugs. Those 4 clips on the one side are ridiculous to try and snap free. When I did my plugs I loosened the vent hose from the 2 bolts on the air intake side and left it attached on the clip side.

Not sure if ECS offers lifetime replacement on that part, but FCP does.
In any regard, I'd buy OEM on that one.

P.S. Black Gorilla Tape can help keep it sealed until the new part arrives!

Thanks for the help guys. Greatly appreciated.

Well, got everything back together. Car idled and drove much smoother, power smoother. Much better. Decided to drive the car around town a bit and everything seemed much better.

Coming off the freeway ramp, got the dreaded "drivetrain error, engine power will be reduced, yada yada".

Darn. This and rough idle was why I started with replacing plugs and coils.

Drove to a few places, car seemed fine. Stopped, started, went a few different places. No probs. Stopped at the grocery store (last stop before home, go figure). Came out, car won't start. NO starter turnover at all. Battery seems fine. Wife comes with other car, try to jump. No deal.

End up having to leave the car in parking lot. Late at night and it's 15 degrees and dropping. Will have to go back tomorrow and try to read codes. Hopefully I can get it started. Not off to a good start, unfortunately.

Car is 2011 535i xdrive. It's my daughter's first car. Any advice on how to best proceed will be greatly appreciated. I have been working on my own cars for 30 years. Fords, Pontiacs, Porsches, Toyotas, Nissans, now this BMW. Car has 107k miles on it.

Thanks again!
