Hello all, I’ve had a 650i F06 Bj 2016 for a few months. Currently 75,000km are down. I was at BMW today because of a smaller repair and have explored myself regarding a transmission flush. Has not been done yet. Before, I have no problems with the transmission, however, according to my knowledge, one should make these to prevent future problems. Now the service colleague has said that it is not intended for my model from BMW at all a S Is that how you do it? If I still want to do it, how many kilometers would you recommend it?
