Is this the right drain plug?

[hcbeck2689]

So I changed my oil the other day and ran into a problem. I bought all my stuff from the local dealer. When I went to put on the new crush washer it didn't fit. Was way too small. I had my girlfriend run me back to dealer in her car. I was able to get a washer from them out of the shop, but they think the plug is not OE. Ye mechanic said it should be a Allen wrench head and not a hex head. Is this correct? What does y'all's look like?

Is this the oil drain plug? If should look like this: http://www.ecstuning.com/ES1895506/

The BMW Part number is 11131273093, at least for my '05 330Ci ZHP.

I guess I should measure my old crush washer and that would be a better indicator of the bolt is too big.

BMW dealer?

Your mechanic is misinformed. It's not an Allen head.

He may be thinking tranny/diff.

Ok that is what I thought. I was in the parts dept and I was asking the guy if it would be different bc it is an m sport package and he said that it has a regular m54 engine. I assured him that I knew for a fact that the engine was different in some ways, but he disagreed. The mechanic overhead us and butted in to comment that only internals are different, which is what I thought. But after that I didn't have much faith in the parts guy. Does anyone have an old crush washer/plug or know the diameter of it? I don't want to buy a new plug offline to find it doesn't fit bc my pan has been drilled and retapped.
