Additional Notes
- All three configurations listed for the BMW Z4 Coupé E86 share an identical rear differential fluid capacity of 1.2 liters, applying equally to the 3.0si and the M Coupé variants across the 2006-2008 model years.
- The 1.2-liter figure represents a service fill capacity, meaning the volume of fluid required when servicing the differential under normal operating conditions rather than during a full mechanical overhaul where additional passages and components may retain residual fluid.
- The Z4 Coupé 3.0si is listed in two separate configurations: one for the standard rear differential and one for the rear differential equipped with a differential lock. Both share the same 1.2-liter capacity under normal use conditions.
- The presence of a differential lock variant alongside the standard differential for the 3.0si indicates a mechanical locking mechanism is available on that model, yet the fluid capacity remains unchanged at 1.2 liters regardless of whether the lock is fitted.
- The Z4 M Coupé (2006-2008) is listed exclusively with the differential lock configuration, and no standard open-differential entry appears for the M Coupé in the specifications.
- All capacity values across the three rows are tied to normal use conditions, meaning the 1.2-liter figure applies to standard driving environments rather than severe-use scenarios such as track driving or extreme temperature operation.
