2011 hitch install diy?

So, dropped off my car yesterday. Then called around four o'clock for a status update. The install was done, but the ECU update was going to take overnight. That seems weird to me that the update takes so long, but it must rewrite a whole new flash on the ECU for when the trailer wiring is plugged in; the X5 will automatically changes over to towing mod. Meaning different shift points, different braking etc. I cant believe how advanced BMW is, and the ECU comminucation with the computer is ancient speeds. We are talking 12 hours of sitting on a computer to re-flash the ECU. The only world that comes to mind is WOW!

Yes, it can take hours, but it isn't doing all that. With respect to the trailer, it is simply recognizing that the trailer wiring module is installed, so that the rear PDC can be disabled when a trailer is connected, and so that the trailer stability mode (which is already programmed inside the dynamic stability control) can be activated if necessary.

There may have been other updates required.

Mine took overnight too and it failed the first time so they had to redo it. The update codes other modules in the car as well.

Picked up my X5 this morning. The programming took overnight, but it took the first try. The dealership tried to charge more than quoted, but it did not fly. Final price was $475 labor. I am really glad that I had them install the hitch. The piece of mind of cutting the bumper alone was worth it. Now I can tow my ATV and rent a pop-up this year. I wonder what the MPG is when towing a full load of 5-6K lbs. Max load with the OEM hitch is 6K lbs trailer and 600lb tongue wait; which is very impressive I think.

I recently towed approximately 3000lbs tandem seadoo's with trailer and I averaged 22mpg doing 75 on my 800 mile trip with a truckload of stuff in the back. Didn't even know they were back there on my 35d.

I have to make the installation of the execuhitch which seems very easy. My only question for the ones that did the Execuhitch installation.... What about the electric wiring for a 2009?. Easy ?

[dlauziere]
