Over many years I’ve generally stuck with Redline oils; in part due to the quality, and for they’re excellent, and easy to contact tech dept. On my ‘17 X1 x-drive, Redline’s recommendations (attached image) is MT-LV 70W/75W GL-4 Gear Oil for both the transfer case and rear HOC “Hang On Clutch”, transmission is D6 ATF, rear diff (final drive) spec is 75W/85 GL-5 Gear Oil, but I substituted 75W/90 for better protection. Castrol gear oils are mentioned elsewhere in this thread. The SAF-XO is 75W/90, and Castrol (not Pentosin) SAF-XJ is 75W/140; both are GL-5 gear oil formulations for differentials. |

Transmission fluid drain and fill
Quote:
I tried to reach the fill plug as mentioned, but went a different route, which may be a bit easier and without the risk of getting burned. I removed the intake snorkel and the bottom of the air filter housing. 3 bolts total to acces the fill plug to the right of the TCM? You will need a long funnel to make pouring easy. Hopefully this will help someone. Last picture from the fluid that came out of the transmission @100k Last edited by X1BMWR; 12-29-2023 at 07:43 PM.. Reason: - |

Yes I was doing a transmission drain and fill and commenting on the second part of the post. The S- drive has also a transmission fill plug near the starter pointing to the rear below the exhaust. Maybe I misunderstood but this very hard to reach. I could not find any directions or pictures on the internet, so that is way I posted this picture. Happy New Year |

Hi Gents,
planning to DIY the haldex maintenance and looking for torque numbers. Without TIS it tough to find those, - does anybody have torque figures for main haldex unit (those four bolts)? I've see one of youtube videos on that, but only side cover plate torque numbers were mentioned, but not the main haldex unit. Thanks! |

Correction on your fluids; 70W/75W GL-4 Gear Oil is used for both the transfer case and rear HOC “Hang On Clutch.
In addition, BMW calls for 75W85 GL-5 in rear differentia; although I personally use 75W90 GL-5 as you spec’d above. |

1. replacing hydraulic pump of rear axle diffrential - required follow-up work - Carry out the service function " LMV: Calibrate the pump motor" ( I think it is also required after removing the pump from housing ) 2. oil change or replacing HOC clutch - required follow-up work - Carry out the hang on clutch oil bleeding routine. Service function--> Drivetrain-->Longitudinal distribution-->Bleeding Waiting period of 60s Repeating the service function bleeding routine. |

As I've seen in ISTA manuals ( same as TIS ) BMW recommends to ( in simply words) unscrew HOC and swivel to the vertical position: ![]() Than ISTA says to fill HOC with oil in this position - it looks more possible to put there 520ml when filling plug is rotated -on the top of pan in this position - not on side :/ Right now my x1 is running on 350ml of fluid in HOC , no cells on the dash, nothing strange happens but I am worried if in long therm it can cause some damage to HOC clutch. |
