Kubica, Your PM box was full.....
I think the lack of a real skid plate around the TC was a poor design over sight by BMW.
With these expensive and low TC's sitting mid section in the car, they are exposed to many possible road hazzards which can chip or crack the soft aluminum housing.
As for mine on the car, it is without a doubt cracked. The mount that contains the bushing has cracked in three places thus separating the metal mounting lobe from the actual TC case.
Looks like it is going to be a fun project to replace this Saturday :/ I'll be sure to keep ya updated on my progress.
