WTB: 13 Button OBC Code Plug

[Klug]

Looking for the 13 OBC coding plug for my '89 M20B25 325i.

I currently have the 5 6 Typ, which is from the M30 out of an e28.

Part Number I'm looking for: 65811385941

Thanks!

FYI It's the '4 6 Typ' on the back of the plug

Hey Klug! Thought I might be able to help, but alas no. The one I have is a 5 8 Typ. Is there a thread or table on coding plug application?

I actually found this little gem- buried on bimmerforums. (The one I'm looking for is NOT in yellow but #21)

Sweet! Thanks!

I have 3 12.
The only difeence between 3-12 and 3-21 is in the gas tank capacity 55L vs 65L, so miles-to-go estimates won;t be correct.

Do you still have your code plug? I am looking for one to fit my 89 touring. I need a 6 cyl plug (going from a 318I to an S52).
