Hey gents I’m coming up to change some fluids so first off I’ve got a 2020 m340i RWD.
For my differential fluid ( I heard these don’t have a front differential just rear if anyone can correct me ? ) but anyways I’m getting this here, I’ll be getting 2 500ml bottles https://www.fcpeuro.com/products/bmw...mw-83222447362 Next I’m going to get my transfer case fluid changed as well, haven’t seen much info on it but will this do ? And if so is 1 Liter okay or will it need more ? https://www.fcpeuro.com/products/bmw...ll-83222409710 Also if anyone can recommend what transmission fluid to get or if there’s any kits available that include everything. Thanks in advance |

If your car is RWD then you don’t have a transfer case.

Interesting thanks for the heads up, learning more slowly and slowly about the whole thing lol.
So basically if I’m doing fluid change I just need to do the transmission and rear diff ? don’t worry about the transfer case or front differential since my RWD doesn’t have either correct? |

M340xi rear diff fluid change
Hey y'all, just wanted to share a few quick notes on the fluid change I just completed on my 2021 rear diff.
1. BMW uses one plug for the drain and fill. Which means that they expect you to suction out the fluid. Well, I (like a lot of people I'm sure) used the temp sensor plug to drain the fluid. While not a perfect solution, it gets most of the old fluid out. 2. This was the first fluid change at 20k miles. The fluid was black and very grainy. I'm glad I did it, but wished I had done it earlier. 2. Be careful of reinstalling the temp sensor, I broke mine by over-torquing. Had to get another from local BMW dealer, which was priced at twice I could get online. But then, I wanted it asap to finish the job, ugh. 3. Needed 3 bottles of the 500ml G4 fluid from dealer. So like $180 for three bottles. If I was more careful with spillage and not breaking the sensor, I probably would've only needed 2 bottles. 4. Overall pretty easy and now just waiting on BMW to supply everybody with the G5 fluid so I can do the front diff. Supposedly mid July now, but they keep pushing dates. |

I’m just planning to change oil in rear differential, so I want to be sure I do everything correctly. Please let me know what the problem was when you broke temp.sensor? Only error code? Rear differential lock reduced? |
