Original BMW Engine Oil Drain Plug for BMW i3 and i3s Range Extender (2014–2021)

Original BMW engine oil drain plug 07-11-9-908-550 is the screw plug that seals the oil pan on the range extender engine of the BMW i3 and i3s Range Extender, 2014–2021. BMW calls it a screw plug, weighs it at 17 g, and shows it in production from September 2013. It threads into the bottom of the oil pan and comes out at every oil change so the old oil can drain. The part is made in Taiwan and is sold individually.

Original BMW Parts carry a 24-month parts warranty.

Only the range extender i3 models carry a gasoline engine, so only those cars use this plug. BMW applies it across the I01 chassis and the I01 Facelift, covering the 60Ah, 94Ah, and 120Ah Rex battery versions. A worn, cracked, or improperly tightened plug or seal can let oil seep out, leaving puddles under the car or residue around the plug. Stripped threads on the plug or in the pan, usually from overtightening or a poor install, keep the plug from sealing at all. A plug that is heavily corroded or damaged should be replaced instead of reused.

Common Questions

Does this fit an i3 without the range extender?
No. BMW applies it only to Rex versions, which carry the small gasoline engine.

Which battery versions are covered?
BMW shows it on the 60Ah, 94Ah, and 120Ah Rex cars, including the i3s 94Ah and 120Ah Rex.

How do I know my plug needs replacing?
Oil residue around the plug, drips under the pan, or threads that will not tighten cleanly all point to a plug or pan thread problem.

Order it with your next i3 Rex oil service and keep a fresh one in the parts drawer.
