In this video I'm changing the DCT (DKG) transmission oil in my BMW F10 M5. Same gearbox is used in M2/M3/M4 so the process should be similar.

While changing the oil I noticed that some of the brand new cans of MOTUL DCTF had different fluid color. I discovered that the bottles dated 2022 had much lighter color than those made in 2023.
If anyone know why this could be, please let me know in the comments :)
