I might have read one or two posts here and on BF about this. Certainly a rarity.
Might try to hassle BMW for a repair if you are close to the 4 year warranty... Given a buddy with a shop, prolly not worth the effort. But...Worth you reporting it to NHTSA as an event that could have caused a loss of control. |

BMW has a written "goodwill" policy- the dealer can actually approve stuff that is just barely out of warranty.
HOWEVER, it is at the dealer's discretion- if your buddy knows his shop (i.e. The front office/SAs) are bascially kind of dicky, then that's that. Here is the one I was thinking of: https://xoutpost.com/bmw-sav-forums/...r-springs.html Rare though.... Does that make you feel better? Or just super unlucky?? |

Update:
So my buddy and I installed the new springs on Saturday. What a pain in the ass. You know it's going to be a job when you pull up the bmw job manual and each job calls for 4 hours a side and the job asks for bmw specific tools. Luckily we did not need a spring compressor for this. Job went smooth and x5 is back on the road. Passenger spring broke at the bottom about 3/4 of a coil, driver side broke at the top and bottom and the bottom wrapped tight around the control arm, we had to cut it to get it off. Really hope I won't have to do this ever again. Spring orientation in pictures are the same to get an idea of how much is actually missing from one to the other. NEW SPRING ON RIGHT OLD ON LEFT DRIVER SIDE SPRING BEFORE WE TOOK IT OUT DRIVER SIDE RIGHT PASSENGER LEFT COMPARISON DRIVER LEFT PASSENGER RIGHT |

rear spring number is 33536779860 for both sides. I also strongly suggest you buy x2 lower spring pads(3353687003). lower spring guide pad(3353687004). x2 upper spring pads(3353687006)

I have seen this happen multiple times on our ML SUV's around 70k miles. The ends of the spring are subject to getting sand/grit ground into the protective coating where they flex against the spring perches. Once that paint is compromised, winter road salt starts to weaken the spring. Plus, a build up of dirt/grit on the perches holds salt and moisture against the spring and makes corrosion worse. Our's have all broken at one of the ends. Dealer has been clear with us that springs are a wear item. Anyway, not surprised it happens with our E70's as well. On our latest ML, I've been trying to wash that area of the undercarriage better during the winter. Don't know if it will help or not. The British solution would be to make sure your lever shocks leak just enough to keep that area forever coated in oil.
