I can not answer that as the case with a lot of us. But if I were BMW and removing the transmission to fix a problem that has taken so long and at a great cost to them and their dealerships I would not be skimping on a little bit of oil or the added cost of that oil. I would consider it as part of the fix, without putting used /old oil back in that may well be contaminated thus potentially cause another issue. Just my train of thought. I could be wrong in my thinking this way but if I were the man in charge of BMW I would not be worried about the cost of oil and be looking at it as ap preventative Maintainance exercise.@asinop, How do we know they are changing oil? Did I miss something in the recall scope-of-work? I've been asking the same question for some time and not getting a definitive answer as the transmission is removed from the side of the engine case.
