1. A shaft arrangement for a vehicle, wherein the shaft arrangement comprises a shaft comprising a fluid channel within the shaft and extending along an axial direction of the shaft,
wherein the shaft comprises at least one fluid inlet arranged at an axial distance from a first end of the shaft and extending radially between an outside surface of the shaft and the fluid channel, and
wherein the shaft arrangement further comprises a sensor comprising a first sensor part and a second sensor part, wherein the first sensor part is attached to a first end part of the shaft at the first end of the shaft, the first sensor part being within the axial distance, and wherein the second sensor part is arranged to be attached to a first shaft housing part,
wherein the first sensor part is a magnet comprising at least two pieces having different magnetic field orientations and wherein the second sensor part is arranged to detect changes in the magnetic field of the first sensor part due to rotational motion of the first sensor part with the shaft, and
wherein a fluid flow path of the shaft arrangement directs fluid to flow radially outside of the shaft for at least the axial distance so that the fluid flows past the first sensor part outside of the shaft and then travels through the at least one fluid inlet and enters the fluid channel downstream of the first sensor part.
