Air Suspension Failure?

[Maverik259]

Eek. Glad I got my full extended warranty to 84k miles. At 25k now!

Went into the garage today and found the back end slammed. As soon as I opened the door it started filling back up. Once out of the garage, it was at normal ride height again. Do I need to be concerned?

Sounds like the airbags are leaking slowly. I would have them checked out and replaced if necessary.

When your car is on, the compressor will be working continuously. It is not designed to do this. You will shorten the live expectancy of the air compressor significantly and when it fails you'll be looking at a much more expensive repair. The compressor is almost $1000 plus labor.

Hmm alright I will have my buddy take a look for me. Thanks

Would it set off any codes if it was leaking or tell me there's a malfunction?

If it's leaking slowly there won't be any codes, it'll just be the visual tells like you said found your airbags deflated overnight. If you park the car for say a month or two, then it's normal for the airbags to be deflated slightly. If it totally deflates overnight that is abnormal.


If the air compressor fails you'll get a drivetrain malfunction. Might get lucky and it'll just be a blown fuse. Unlucky will mean compressor motor failure.

Hopefully if any of that happens it will be covered under my extended warranty. 🤞🏻 it was just a one off fluke. If it's down again Tomorrow I'll take it in.
Thanks

Don't hold your breath. Suspension components aren't covered under extended warranty as they're considered wear parts. But idk what warranty you have. I know none of the bmw ones do.

Also arnott makes replacement bags and sells on eBay for like $120 a pop. BMW wants $300 a piece and that's discounted on wholesale. There's a thread showing how to do yourself. Not hard and maybe 2-3 hours of work.

I have a third party one, I should get out my paper work and take a look

Bet it's arnott. 🤘

If I bought them again I'd probably go with the X5M ones as I'm lowered and this would allow me lower rear without being too bouncy. Basically just a smaller bladder that when full and stiff sits lower.

Do they fit the same? Or only if you are lowered?

They will fit the same but they will lower the rear m just like the M.

Arnott is direct replacement for F15

I'll take a look at them. If I buy the regular ones locally they are 245 Canadian a piece. I looked at rock auto, even with shipping comes out to 370 for both. I may go that route if I need them.

Arnott is currently $280 for both on Prime.

I just looked, not finding them on the Canadian site. Must only be for the U.S

Are they the same from the E70 to the F15?

[Russmov]

Looks like rock auto is still significantly cheaper for me.

[Sedoy]

Yes they are regardless that oem have different part numbers

Do they really have a lifetime warranty?

[Localbrew]

Looks like mine is failing as well, it's on the driver side and it's hit or miss. Seems to be only when parked on uneven surfaces or dirt terrain. I'm taking it in on Monday, I just don't know how they will see if it's bad if it only does it randomly.

Any thoughts?
