I'd imagine there would be fold particles in the oil regardless of use, as the synchros will always wear with use, and this is still the original fluid from when the car was new.
As it's so easy I might start changing the trans fluid yearly, just to be safe.

Pentosin MTF-2 is
NOT the correct fluid!
MTF-LT-3 is the correct fluid for your car!
All 135i's (N54's) came with
MTF-LT-3 from the factory. I did not even think BMW sold LT-2 anymore - it was last used in the e46 generation cars)
When I changed my fluid(the first time) almost three years ago - my dealer told me that LT-3 had gone to LT-4 specs. I think now, LT-5 is the norm. All N55 6MT models(and the 1M) use
MTF-LT-5 trans oil.
I think you should be running a LT-4 or LT-5 trans oil.
