Servicing your rear differential at regular intervals is important to ensure you maintain both performance and a long lifespan. Over time, the differential fluid can break down, lose its lubricating properties, and become contaminated with metal shavings and debris. Regularly replacing the fluid ensures that the gears and limited slip differential clutch packs are adequately lubricated, reducing wear and tear. Regular maintenance also helps identify potential issues before they become major problems.

This kit includes Genuine BMW differential fluid designed specifically for your M Sport differential and a brand new fill plug. The factory plugs include a rubberized seal that compresses over time and may not seal properly when reused.

One unique aspect of performing this service is the removal of the lower differential temperature sensor. Unlike many typical BMW differentials, this differential does not use a traditional drain plug and instead uses the temperature sensor as a drain plug. This sensor is removed to drain the differential fluid and is replaced before refilling. If you'd like to replace this sensor as well (not included in this kit), please see our recommended items or search BMW part number 33107847469.

NOTE: This kit includes 3 500ml bottles of diff fluid. BMW claims that only 1 Liter of fluid is necessary, but we found that 2 500ml bottles were insufficient. The third bottle included also allows for a minor flush of the old differential fluid before refilling.

BMW manual transmissions, differentials, and transfer cases require specific fluids to maintain optimal performance and prevent excessive wear on internal components like gears and bearings. While these fluids don’t endure high temperatures like engine oil, they still degrade over time and accumulate metal particles and other contaminants, leading to reduced lubrication and accelerated wear. This can ultimately shorten the lifespan of your transmission, differentials, and transfer case. This kit includes all the essential Genuine BMW fluids and drain plugs needed for your vehicle, along with specialized tools to simplify the maintenance process!
