I've always known the clip to be there...this was an OEM tank?

I am always uneasy when I have left over parts after a project or not enough parts.

Nonetheless, I for 1 wouldn't want to take a chance with the finicky BMW especially that expansion tank and its cooling system.
And it's your wife!
Plus at the time that car was manufactured...
Germans were not into decorations...
Sorry, I couldn't resist the last one[emoji106]
