Basically the dent was enough over time to cause a failure in the seal, leading to grease leaking out. Just where the silver metal meets black, I assume. In fact you can still see residual grease in that area, although it's been wiped off. At first it was diagnosed as a split CV boot - same failure, essentially. Definitely the cause of failure as two indies diagnosed the same thing. The first did not have the correct tools for the job. Tellingly, as an approved BMW independent, they requested the correct tools to remove the driveshaft from the official BMW dealership I believe did the damage, and were told they did not have them (probably why it got banged in with a hammer originally!).
