I don't want you think that we are disregarding your request so i wanted to make a couple things clear.
We have seen this happen to a number of shocks and we have tried to warranty them as well. Unfortunately from what i can see in your pictures, Bilstein will not warranty the shock for that amount of leakage. Here is a snip on there warranty policy that you posted the link to
As you can see, Bilstein states that this leakage is a completely normal occurrence. With that said, I would recommend pulling the shock and check to see how it compresses, if it comes right back after you release pressure, if there are any odd noises, or if there is any binding in the travel. If your shock does not have any compression or rebound dampening, does not return once after being fully compressed, or binds- That can generally constitute a warranty claim.
Please understand that this is not our choice to not warranty the shock for you as we have to go directly through Bilstein and it is totally up to their discretion whether or not to issue a warranty. If we send your shock in for warranty and Bilstein deems it not a warranty issue, you will be out shipping and your shock as they do not ship shocks back. Because of this, we want to make sure it is something Bilstein will consider for warranty.
If you feel the leaking is excessive or have any other questions, Feel free to PM me on here or give me a call. Our number is 1.866.254.0076 and my extension is 102.
