I think the problem is that BMW saying the CVT fluid is life-time. But the document which I found on the internet says: "10. Drain & Refill A refill of the transmission oil is necessary every 45.000 km" . It's appx - 30K miles
Sorry, I could not attach a pdf file. Somehow the max size for this type of files on this forum is 19KB and mine is almost 2 MB. BTW. Extremely interesting document.
would you mind emailing me the CVT document, I have an 04 with 70,000 on the original tranny and just trying to find out the best ways to keep it going. My email is dancherrman@yahoo.com . Thanks.
BMW actually reccomends the fluid to be changed at ever inspection service. And let me tell you, it sucks to do.
