Replacing the oil level sensor (BMW X5 E53)

The oil level sensor must be replaced in the following order. Turn off the ignition, unscrew the oil filter cap and allow time for the oil to drain into the oil pan. Remove the engine auxiliary protection panels and the stiffening plate.

Drain the oil from the engine and disconnect the shock absorber (1, Fig. 6.95) from the oil level sensor. Unscrew the nuts (2) and remove the level sensor (3).

The installation of the oil level sensor should be carried out in the reverse order, while it is necessary to clean the sealing surface of the oil pan; replace the sensor sealing gasket; pour oil; tighten the oil filter cover to 33 N·m (3.3 kgf·m); run the engine for 5-7 minutes, turn it off. Let the oil drain into the pan and check its level, restore it if necessary.
