Why would BMW state lifetime and not state say 130,000km to change the transmission fluid? It would be in their best interest to have you back at the dealership in 130,000km. So who, knows really.
I will change at 130,000km also.
Exactly right. Pretty sure BMW knows more about these things than people here.
