Drain/fill bolt sizes

Bishop200 · 07-17-2009, 02:25 PM

Hi guys,
I have just ordered the 14 and 17mm drain plug sockets from Bimmertools.com. I haven't received my 128i yet (soon, please...) but it occurs to me that I may not have needed both. Can anyone tell me what size the transmission and differential plugs are?
Thank you.

The manual transmission, both drail and fill are 18mm:
05 Screw plug M18X1,5X18 23127564721

The differential (fill only) looks like a 14mm.
M14X1,5-10ZNS3 33326760380

Thank you very much for the reply, Lester.
Looks like I have a 17mm allen socket that it going to languish unused in my toolbox. Oh, well.

So for the tranny, that's an 18mm allen head? I have the 14mm allen head for the diff, but if the tranny is an allen head also, I'll need to order up on of those.

That is what it shows up as on realoem.

I have yet to come up with a place to order an 18 mm hex socket. If anyone manages to find one, please let me know.
Thank you.
