UPDATE: Oil drain plug is no longer aluminum on US F82s starting Sep. '14
BMW has changed the oil drain plug on US spec F82s starting in the September 2014 production month.
Disclaimer: I did not confirm the above for cars spec'd outside of the US, and I did not confirm for other F8X variants (F80/F83). Original post: I was under the impression from other posts (namely the 1200 mile service guide that is sticky in this sub) that the oil drain plug on the F8X is aluminum and would be replaced with every oil change. However, after doing my in between oil change this past weekend, I noticed that my car has the steel style drain plug with the replaceable copper washer (same as the F32). My car: USA spec F82 M4 production week 37 (9/8/14 - 9/14/14) Part number for aluminum oil drain plug I thought was correct: 11117849396. This plug uses an allen key, the steel plug that I have is much thinner and is 17mm socket. I should also mention that there is no way the above mentioned drain plug will fit, it is much wider than the hole in the oil pan (I thought maybe the dealership that did my 1200 mile service changed it). So, for an oil change for cars similar to mine (all USA F8X?) one only needs the oil filter part number: 11427566327 which comes with the copper washer/o-rings and the oil itself. Has anyone in the USA confirmed they have an aluminum oil drain plug?

I'm no metals expert, but i wonder if the oil pan material determined what plug was used. Don't our cars have a magnesium oil pan or am I'm thinking of another model?

Correct, the oil pan is magnesium and I expected the drain plug to be different in the F82 than my F32 for this reason, and per the sticky in this sub.

just had my service done, SA stated that the plug was not replaced. I didnt get the chance to go into the bay and physically inspect and verify the composite of the plug. Can I assume that since they didnt replace the plug that it's steel and not aluminum.

Therefore the service should only replace the copper washer which comes with the oil filter.

When I had my 1200 mile service done it took an extra hour because the my SA said the washer did not come with the filter and they had to send someone out to get one. Perhaps it was a packaging problem, but I would have thought they would have opened another filter to see if the washer was there.

However, that drain plug is too large for my oil pan, and I was confronted with a steel plug when I was doing the change, so it may have something to do with the mfg. date. Can you please post your production week for reference? My F82 was produced week 37 in 2014 (9/8/14 - 9/14/14) and this is the drain plug type that I have on my car here which is the same steel plug with copper gasket used on pretty much every BMW model.

Ok, after further research it looks like BMW changed the drain plug type in the September 2014 production month. Per realoem all the 9/2014 and forward oil pans use the steel 17mm drain plug with copper gasket. Therefore, you are only required to replace the copper gasket when changing the oil, and this is the same gasket used in most BMW cars so dealers should have them handy.
All US F82s produced before September 2014 will require the allen key aluminum plug. I assume this could be the same for the F80 and F83, but I did not check.

Thanks, that means you had the last production month for the aluminum plug per my last post.
