I am just about to get started on changing the oil on the CT and just want to verify which bolt it is. There is one at the back center of the pan right under the axles and one on the side of the pan left side of car. If I was working on an American car I would have had the oil changed before I finished typing this post. Lamborghini............I don't know so well yet. Help please!

The off center drain plug at the rear between the half shafts is the differential drain plug. The plug on the side of the large pan is your oil plug.

Got it. Thanks. That was easy to do.
