Oil Pump Tensioner Spring, BMW - E46, E39, E60, E83, E53, Z3, Z4 (M52TU, M54)

This part is listed by BMW as BMW part number 11417502774 (11 41 7 502 774) and is described as the tensioner spring for the oil pump used in M52TU and M54 engines in 1999+ E46, E39, E60, E83, E53, Z3, Z4 models. Springs lose their own tension over time and use so if you have the oil pan off and want to service the oil pump this is a key part.

An o-ring should also be replaced - BMW part #11411722837. See Related Items below or buy the complete bottom-end gasket kit that will include the o-ring plus other gaskets you'll likely need. The outer circlip does not need to be replaced but may be good to have on hand in case the original flies off to parts unknown.

This is a Genuine BMW oil pump spring with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
