Broken leg?

Patricius · 06-28-2008, 09:25 AM

While driving through a parking lot @ roughly 10mph, I heard a loud pop followed by an "air-rushing" noise from from the front passenger side of the car. From there on out I have an audible rattling noise when the front pass. suspension is under greater-than-cruising load. My guess is that it might be an EDC failure of some sort, but I don't know exactly how the EDC system works (I need to do some homework).

I took it into the dealership immediately and got a 335xi loaner

I am not too pissed because it's a new car with a new suspension/gearbox/engine and things will come up. I just wanted to share my experience with the board thus far and see if anyone else can provide guidance or ideas as to what exactly might have happened.

odd....a blown EDC shock I guess??

Patricius · 06-28-2008, 09:55 AM

It drove fine afterwards just had the noise. I'm thinking its the EDC mechanism. I'm getting zero malfunctions... I'll update everyone when I hear from the dealer on Monday.

MDCTFTW · 06-28-2008, 11:38 AM

The EDC mechanism is just a motor at the top of the shocks that adjusts damping. It sounds like a completely blown shock.

Could be EDC but then I would think you would get a Malfunction.... keep us posted

Big Windy · 06-28-2008, 11:45 AM

gotta be a blown shock or another failure of a piece of the suspension. EDC failure is unlikely because 1) no warning and 2) if it failed you probably wouldn't hear a popping noise or the rushing air. tire was okay, right?

monsta · 06-28-2008, 11:50 AM

Damn, Pat...good luck hopefully nothing major, I guess we're both w/out our beloved M3's for this weekend....

Patricius · 06-28-2008, 08:22 PM

The tire is fine. Zero TPMS warnings. If it were a blown shock, I'd only have the spring holding me up? If it was a total shock failure, wouldn't it be more intrusive to driving?

Is this confirmed? I thought EDC worked on electric current flowing through metallic particles in the shock oil?

hmmm...i thought from the diagram that there was a motor or mechanical device above each shock. don't know about the electric current though.

Funny enough, it was part of a tree branch stuck in an underbody panel. The wierd part is that the parking lot was entirely clear, which means I picked it up at another point - that I can't remember ever driving anything like that. The pop was part of it snapping, the air rush was the sound of it scrapping against something, and the rattle was it rattling off something under load.

Strange, somewhat embarassing, but I'm glad it wasn't shock failure.

$19 in labor later and we're purring again

great story...and here we are all taking all these guesses about EDC and the shocks. did you ever look under/behind the wheel? either way, glad your car is okay!

Patricius · 06-30-2008, 02:59 PM

Yeah, I visually inspected everything in the wheel well BUT the underbody. They stated it was pretty concealed anyway, needing to take off a panel to even remove the branch.

No, EDC system uses electrically operated valves, not ferromagnetic fluid.

I ran over a baby rabbit Monday. Swerved to avoid the thing--but he ran towards the car. Bad way to start the week. (For me and the bunny)
