    It’s hard to believe that material would completely snap like that. Once a small crack or split occurs there would be immediate pressure loss and separation would cease. I don’t mean to make any accusations, but when I blow up the picture it looks cut rather than torn.

    3psi is nothing when it comes to the force exerted on a pipe...there has to be more to the story.

    If it is cast iron this could happen. That's more briddle.
    Could be that he ran over something which caused a hot cracked pipe to break...
    There are two theories to arguing with women. Neither one works

    But, rare to break charge pipe at just that Kpa/PSI level or backfiring tune? But, who knows... BMW parts comes from different supply chains & sometimes issues not known yet since N55 kinda new. Will try not to assume.

    You make a good point.

    This could be just a freak failure, nobody has experienced anything like this from what I have seen.

    It does somewhat look cut but what would be the point of cutting it and making this up? None.

    Speculation aside, it should help spur the aftermarket to create a replacement. Silver lining

    I looked at this piece on my car today and noticed that there is a plastic "weld" in that spot. I take back my opinion that it may have been cut. Now I vote for a real weak spot.

    Maybe the victim of this situation should go for a warranty claim??????

    Take that JB off!!

    That almost looks like something called "back fire". I don't think that's a factory defect though. Those plastic welds have been used for years without issues. I could be wrong though. Let us know how it goes with the dealer =D
