Original BMW Engine Oil Cooler Line O-Ring (13.4 x 1.78 mm), F30 328d, F10 535d, F02 740Ld xDrive, and F15 X5 xDrive35d (2014–2018)

Measuring 13.4 x 1.78 mm, this Original BMW O-ring seals a connection in the engine oil cooler line circuit on the 328d, 535d, 740Ld xDrive, and X5 xDrive35d diesels. Part 17-22-8-573-882 has been in production since December 2012. It replaced the earlier 17-22-8-511-460, and BMW marks the change as exchangeable retrospectively, so the newer ring is the correct fit wherever the older number was used. The ring weighs 1 gram and is made in France. An O-ring sits in a groove and is compressed between two mating surfaces, which stops fluid from escaping at the joint.

Original BMW Parts carry a 24-month parts warranty.

The oil cooler lines carry hot oil from the engine to the cooler and return it once it has been cooled. On a water-to-oil design, engine coolant takes heat out of the oil, which helps the oil hold its protection under heavy load. Cooler line fittings can corrode with age and exposure, and a corroded fitting can leak or become hard to service. While the lines are apart, inspect the pipes and hoses for leaks or deformities. The ring measures 13.4 x 1.78 mm.
