I have a 2011 825I and as soon as it got cold outside (below 40F) I started to hear a lot of strange noises from under the gator, it sounds like it starts under my feet and goes to the rear. I sounds like a metal on metal clank. I put the machine up on jacks and tried to find the noise but it did not make the noise then. I then left the machine in the heated shop over night and the next morning drove it, no noises. I thought maybe it was the transmission oil getting thick in cold weather so I changed the tranny fluid but that did not correct the issue. I have crawled up under it and shook the h--- out everything trying to isolate the noise with no success.

Has anyone else ran into this issue?

Thanks again,
Dave
