Hi everyone, I own a 2012 F10 528i Msport (ckd). Mileage 138k kms. Car in perfect condition so far. No more warranty.I still send the car for the regular service at Auto Bavaria every 10k kms. So far my transmission oil has never been changed before. I have asked Auto Bavaria KL to change the transmission oil at my cost but they refuse, saying that the F10 transmission oil is life long and need not be changed. I don't believe this theory at all. So far the the 8 speed ZF transmission in the F10 is superb without any problems. I wish to change the oil but Auto Bavaria saying no need. Of course of I were to send it to be replaced by outside mechanics they will happily replace the fluid. Just want to seek expert opinion here on whether you guys actually change the ATF fluid expecially when the car has already done 100k kms. Tq
