If you just pulled the box out, pulled the cable, then reassembled.
Now the idle is bad. I would say you broke a soldier joint in the connector.
I would bet if you reflow the soldier connections to the external connector,
the idle will work again.
If this doesn't work, mail-order a used box from one of the salvage
yards listed on my bmw_parts page. www.unofficialbmw.com/parts.html
You should be able to get one for around $150 - $200.
