Yes to your second question.



The oil change process is not detectable/traceable.
I thought I had read elsewhere that you had to run the DCT pump to drain more fluid and that was only something the dealer could do (but wouldn't since it's "lifetime"). Is this true or not necessary. I guess if the net yield was only 0.5L or less that I would skip, but do you know if that's needed or not?
