It is my fervent belief, that US dealers do not know how to program this feature. Nor are they willing to learn. What a shame. I could really use this feature when backing up to a heavy trailer. They just tell you it cant be done, and that is it. It is going to take the skill of some indie, or coding specialist to figure it out, and when they do, they will have my business.

Given that the iDrive hardware changed, it isn't hard to imagine that the feature is no longer supported, as mentioned above. There are quite a few differences between the two generations of electronics.

The fancy sway control is already built into the Dynamic Stability Control, on all X5s (and on my X3). It has an additional trailer sway detection feature, which is activated when a trailer is connected. The only coding that is required is to get the vehicle to recognize the trailer wiring module. If your lights works, and the rear PDC turns off when a trailer is connected, then you're there.

That said, in years of towing with the X5 and X3, I have never had it activate. I can get DSC to light up on a wet or snowy road, but I have never had a trailer sway enough to require dynamic brake intervention. That includes towing through the Rockies in winter in snow and slush.

makes sense, like you said if the trailer lights work and the PDC turns off... totally makes sense that the coding was done fine. i'll be giving this a shot hopefully tomorrow afternoon.

thanks!

^^ If you notice, a lot of the new pickups from Ford and GMC are now coming with the trailer sway control feature. I've never had trailer sway towing the boat, but with a travel trailer, I think that there is more risk of sway.

I suppose if you're not satisfied, you'll need to hook it up and verify the codes yourself...(personally I have no idea how to do that, but I'm sure there's lots of info how to on this forum)... I'm quite happy with the service I received from the dealer. They were as interested to see this feature working as I was.

When you plug the trailer harness in the beeping from the backup sensors will stop if the trailer programming was done

just wanted to update this thread... i connected up my trailer to the x5 yesterday and everything works great! the little tow icon shows up on idrive screen when back up camera is turned on, no zoom function for newer X5's (mine is a 2012) but the back up camera view angles are so good that you can easily line up the trailer ball to your trailer, very nice.

yes reverse beeping is turned off, as well as the hatch will not open by pressing button inside the cabin. however, if you are outside of the vehicle and press the remote hatch open with your remote, it will open.

overall the x5 tows like a dream. i had a 2010 Ford F150 prior and towed the same load... i will honestly say that the x5 rivals the truck i had in terms of towing performance. it really is that good. great job BMW

I have to agree. They tow very well. I just towed this 530 for 400 miles without any problems. No reduction of speed when going up hills either. This is one sweet tow vehicle. Mine is a diesel.
