Thanks for the towing capacity code. I will ask my salesman on Monday about adding this to my order. I hope that I am actually able to order this. Since it is a free upgrade when ordering the hitch as compared to air leveling suspension. I wonder how you get the air suspension. I wonder if you get air suspension when you order the 3rd row seating. I do not want the 3rd row seating so I am going to have to do some more research to find out how I can get the air suspension.

I am trying to use the European hitch purely for aesthetic reasons. I do not like the fact a square must be cut into the bumper over to allow room for the receiver. In addition, you always see the receiver when not in use. I much prefer the option of either, pushing a button and the trailer neck just drops down (electric) or, manually installing the trailer neck. With either option you will not see the receiver when not in use.

I read a post where the OP had installed an "exuhitch"? It was stated in that post the X5 has been pre-wired for trailer towing and, the wiring is located in the RR of the truck. It is my hope to purchase from a Euro dealer the hitch, install it, plug the wiring in and, then take to the dealer for coding.

Back to the towing capacity thing real quick. Do you know what you get when you order code 233? To me it would make sense that if you from the ability to tow 2.7T to 3.5T there would be additional oil coolers for the tranny and possibly the diff as well as an increase in cooling capacity. I would be curious to hear from anyone with code 233 to see if they could provide some insight.
