Check Engine Light Due To Rough Idle (E71 X6M)

[Too__Hu///Mble]

What's up y'all, I'm not sure if I have aquatinted my self but I'm an ///M owner.

Ironically I have "cmyx6go" car.

He did a great job taking care of her. I call her (Betti)

But I did something one day. I know don't kill me. It's an honest mistake of after 5000+ successful gas fill ups. I didn't put the cap on. So I drove briefly seen and noticed it was uncovered via side mirrors, then I covered it back up.

Now, after that incident I noticed I had some rough idling. (Fell under 500 RPM with immense rattling) I was like this ain't the bass beating like that.

I attached photos.

What I'm asking is what a causes for a vent pipe to fail? Was it caused by me having the gas cap off and driving or something else?


I was interested in some insight from you guys and reference materials. I love this car and want to learn more about it and BMW itself.

I know this is perfect place to come to.

All responses are welcomed.

Thanks!

A loose gas cap will throw the check engine light. Tighten it up, drive on and the light should clear. It has happened to me a few times over the years if the gas attendant didn't tighten all the way. I've never had to go to the dealer though. Not sure if the vent pipe, coincidence?

And by the way, I'm a she. I hope you are enjoying my ride. I miss her everyday.

could it be you have air in tank since you drove without gas cap?

What you had replaced was the crankcase "vent pipes" they are very common to fail due to getting brittle from all the heat with top mount turbos. Not related to gas cap. But a missing gas cap can pop the check engine light. Just install another a clear the faults.

Good looking y'all. I learn everyday. I appreciate that. Thank you.

I understand that now. (Sorry for the late reply, I didn't get any prompts) a nice lesson for me.
