Does anyone know how often the 7spd DCT & Rear Diff Fluid should be changed?

I did not see any info on this after reviewing previous threads.

Bmw's service sheet says every 5 years or 50,000 miles, to me that is extremely long especially for a car that has a pretty finnicky diff that has a history of blowing up (they stopped delivery for months in 2016 to recall the diff). So imo if you want the car to last I would do every 4 years or ~40,000 km whatever comes first (essentially half of bmw's recommended range).

Me personally I do it every 4 years because I don't drive enough to hit the mileage requirements.



I don't have a dct so I have no clue about range and intervals as I didn't look it up. But I would also do it every 4 years or 40,000 km just like the diff (I use the same intervals for my 6mt). I also believe the dct has a filter which you may need to change as well.
