This is the throttle body from my Z3 19.i. I can identify the unit on the left as the throttle position sensor but what is the unit on the right with the other electric plug?
The idle valve.
A very-very expensive part if you break it with thousands of cheap chinese knock offs that claim to be able to substitute it.
Never touch it, never try to open in (in contrary to what youtubers say) and in general leave it there doing its work.
