Wild tire mishap, wiped out ABS & Air Susp.

I would love a bit of help after a wild ride. My driver's side rear tire blew off the rim, but stayed inside the wheel well, flapping around. It tore up the black abs plastic wheel well pretty good and it wiped out the inboard side of the ABS Wheel speed connector. The connector itself and whole wire and speed sensor assembly are fine, but the inboard (harness) side broke off the wires right at the connector. Fortunately, I the dealer sold me a connector pigtail which I can splice into the main harness.

ABS, Brake, and traction control warning lights are all on and speedometer is now out.

The other thing that got knocked out is some black poly tubing that I believe goes to the air suspension. I can't find a part for this online and the dealer told me it would be $300 to diagnose, would need a new air tank, a set of air shocks, plus they would have to test the compressor, would cost more if I need a new compressor. I told him it was one of the black poly tubes that was just cut, asked if he could get me the part, they said "no, we only sell these parts if part of dealer repair service". WTF??

Does anyone know what actual size tubing this is? Can I just find something similar at an irrigation supply store and splice in a repair? OR maybe let me know the part to request and I can search online or at a BMW salvage yard?

Has anyone else had to replace just the tubing from Air Suspension?
Any help would be appreciated.

Drew

That dealer is full of it. I can't believe how these guys operate sometimes.

The black tubing is nothing special - you can probably pick it up at an auto parts or farm supply store. Fastenal or even a pet/fish supply store may have it. Just cut off a small length and bring it in with you.

I run a BMW salvage yard and an 03 X5 4.4, let me know a list of everything you need and I'll quote you a price. I have the fender liner and everything else around that corner of the truck.

I'd pull the hose too but its probably brittle with age and you'd be better off getting it new.

Let me know if you need anything.

Brian

Thanks, Brian! I'll get under the car again after work, take a better look to see what else I may need. Do you ship parts? Also, do you know think I can cut out a section of the tubing and splice it? I can't really tell where it routes too, I only see a small section of it peeking out from the wheel well liner that was torn open. I am assuming it goes to the canister, but I'm not even 100% sure of that... I can't find any good diagrams or illustrations, except for a parts explosion, which doesn't show parts in relation to where they are installed in the X5. The other thing, I noticed, is that the ABS Wheel speed sensor connector (inboard or harness side of connector), up under the wheel well, seems to have two sets of cables that were cut... one, appears inside the wrapping to be simply two white small gauge wires, which I believe do go to the connector for ABS wheel speed sensor. I think there is a set of thicker gauge wires in the wrap too, that were torn off when the tire blew, but I can't find another end where they go... these thicker wires now are all frayed copper strand wires, where the insulation was all torn off, so I can't even tell what color wires they were... any clue what the other pair of wires in that same harness are for, where they might go? I don't have a lift at home, so I haven't been able to get the tire back off to further investigate, cut the wire harness wrapping back further..

I have rear air suspension and have replaced parts on it (rear air springs and the height sensor).

There are no under the car air hoses for your rear air suspension, it's "fed" from inside the car. The three most likely things that may have been torn up are the: (a) ABS / wheel speed sensor and/or wire, (b) the brake pad wear light (can't remember if it's on the left or right rear wheel) and (c) the wire to your ride height sensor.

You don't need new shocks (at least due to this failure), or a compressor.

A picture or two would be VERY handy at this stage.

Sorry for your trouble. There is an X5 on craigslist in Tucson being parted. See if he has what you need?

I ship parts all the time, so thats not a problem.

I'm not sure I have much to add beyond what Gregory has said. Without seeing the car and the wires it's just too hard for me to guess at whats going on there.

I assume you were looking at realoem for the diagrams?

Great feedback guys! I'm going to take some pics this evening, then post for comment. I am kinda scratching my head now, especially the tubing... I know it's not the Windshield Wiper fluid tube...that runs in the ceiling for the X5... I also have eliminated the tube from the expansion tank to the shock, but I think it may be from the top of the fitting on the tank that maybe routes around to the compressor... not sure..

I'll snap some pics of the wiring and tube that got whacked!

Here are three pictures, that I hope will elicit some help...
First picture, is an over view shot, rear driver's side wheel well. (Sorry, my floor jack took a dive, so tire is still in place)
Note the blue wheel speed sensor connector is still in place, but the black weather proof housing has vanished, knocked off by the tire. Also, note that the wires on the top of the connector, which go to the wiring harness were cut off, right at the to of the connector.

Also note the shiny copper wires that are exposed. I can only assume these were to the connector, but they sure seem like a MUCH heavier gauge than the two tiny white vinyl covered wires that come out of the top of the connector.

https://www.dropbox.com/s/k9l3dzq2c8vw30t/IMG_4224.jpg

In the next picture, I am pointing with my finger tip just barely touching an approx. 1/4" black poly tubing that was cut from the tire flapping around. (bad picture, sorry).

https://www.dropbox.com/s/cak3940v9dvik59/IMG_4225.jpg

In the final picture, you can see my finger pulling out the other section of the broken poly tubing, which is just peaking out from the back of the wheel well liner, that was ripped away.

https://www.dropbox.com/s/1k7clq39owtn51f/IMG_4226.jpg

I just want to be sure that this is indeed the air suspension poly tubing and not something else. I can't very easily get to it behind the wheel well liner and I can't see where it goes from the trunk/spare tire compartment, without a ton of work.... it might be that ultimately I need to go to a good service shop, but I'm actually pretty handy, can do a lot of basic auto repair jobs, but I've never really worked on this X5 and have been super snake bitten by repair shops and the dealer on this car.

Any help in identifying the tubing and whether I can just try to splice it or have to go to the dealer and buy the whole tube, would be great. Also, if you can see the copper stripped (shredded wiring) in the picture too, is it possibly a different wire than to the ABS Wheel Speed sensor ?? It just looks too thick to be for this connector, but I can't find any other wires nearby...

Thanks for any help.

Drew

Could the approx 1/4" hard poly type tubing I showed pictures of, above, actually be a fuel tank evap line??

I think that poly tubing is the rear differential vent hose.

This here:
