Ya, I'm on top of my fluid changes too. Color is always red, to dull red.... Just soft disc and band debris.

Ya, I do drive tenderly Mr. Redliner. I drive like grandma on the streets. I only beat on my vehicles at the Track. The X5 isn't one of those vehicles.

ZF...X5 tranny oil..... Color of oil last change.. (look at the drops) Oil replaced with Castrol multi import oil.
