Either way I was thinking about using two friction sway control units.On an unrelated issue I have a trailer interface module but I cannot seem to find the harness that goes from the trailer interface module back to the towbar for a reasonable price, VW wants $450. Thank you to both of the posters that replied I appreciate your input.

I went thru retrofitting a tow package on a Cayenne. It will be similar (electronically) on a Tourag. The parts are not cheap and the system runs thru the Can/BUS system. So the electronic brake controller plugs in by the driver and has to get wired to get the brake signal and also to send the correct signal to the 7 pin.... I believe all that is controlled thru the can/bus system.

Your other option is to bypass the can/bus all together and route the wiring all back to the rear lights and hardwire the 7pin connector and bypass the can/bus.

Regarding the sway. I believe the concern is that the trailer has sway. The cayenne or Tourag stability control system controls the stability of the TV. The force diagram of a trailer swaying is coupled to the TV thru a pin joint (the hitch),and the forces are in the cross-road direction. That force is a coupling of momentum (M*V). The short wheel base and contact patch area of the TV tires are not desirable to control sway of a trailer. Having sufficient tongue weight (10-15%) is necessary to move the center of mass forward on the trailer itself to shorten the effective moment arm of forces to induce the sway.

In my opinion that is the real safety question of pulling a large trailer... I believe that the Cayenne or Tourage has the ability to pull sub 7000 pounds and since the trailer has brakes, it is probably safe at braking that trailer in may conditions, but the limitation will be having sufficient tongue weight vs. gross trailer vehicle weight.

So if a Tourage has a 750LB tongue weight limit (if you read the threads, this is correlated back to axel weight limits... pending some assumptions about cargo in the TV)... then a gross vehicle weight for 15% is 5000lb and 7500lb for 10%.

I have never tried it, but Hayes does make a dynamic brake sway controller to control the trailer brakes if it senses sway on the trailer. It connects in-line between the ECB and the trailer brakes. This may be a better option because it applies a force at the trailer wheels where you have the best chance of creating an opposing torque (perpendicular distance * force) to counteract the forces creating the sway. I think the cost is around $350

Use ProPride or Hensley and you will not experience sway. I towed 33 ft long trailer with BMW X5 through strong cross-winds, including those in Wyoming. Sway is not an issue with these hitches. And this was not with Airstream, but SOB which has worse aerodynamic profile.

FWIW, in response to Don and his newly acquired AS, I also vote to get a WD for safety sake. I have a 2014 Touareg TDI pulling a 23D and I currently use Equal-i-zer, so far so good and tad bit cheaper than other brands.

very small budget

I have ay small budget for my travel trailer. My first Airstream which I call the wrinkled Twinkie I bought off the side of the road for $700. But I wanted a mid seventies 31 foot with awnings on both sides aluminum propane tanks and aluminum wheels in good enough shape to use as purchased. I bid $4,000 on more than 30 Trailers on eBay that met that criteria. The one that I finally got was in better shape then most of the ones I did not win. We have taken the wrinkled Twinkie To Ely Minnesota Which is a 150 mile trip for us. I also used it as a place to stay when I was working two hundred and fifty miles from home. It was a year-and-a-half ago when we got the 31-foot, we have taken it to Mount Rushmore and too many u.s. forest service and State Forest Campgrounds near our home. Until a few weeks ago we had to borrow vehicles to pull our trailers. I am a professional auto mechanic so I have many friends and relatives Willing to allow me to use their vehicles intrade for Discounts on service and repair.

I like the fact that the bulbs are monitored when using the trailer interface module and I also like the shift strategies and different engine management strategies via the can bus interface. All I need is the plug for the trailer interface module and I can build the rest of the harness back to the tow bar myself.

My Touareg has the same contact patch as my brother's Expedition but with the shorter side wall I believe it is more resistant to side loading. It has comparable or better brakes also.

I thought that there was an Airstream accessorie That used the trailer brakes to control sway. My dream would be to design or adapt anti- lock trailer brake system with built-in sway control. How about disc brakes. Those things would be for another thread, as I would not want to hijack this thread.

Thank you to everyone who has contributed their opinions on my situation and I apologize for the speech to text system I am using to write this.

what I was talking about

2008 Porsche Cayenne marketing info.

"Trailer Stability Control detects any pendulum motion on the trailer and intervenes by applying the brakes
individually as required in the interest of enhanced brake stability."

Do not bypass the factory tow package with integrated sway control. I was using a recommended sway control WD pulling the 30' Bunk with the ML350 and came out from under an over pass in the middle of a curve when a very strong prairie gust of wind sent the whole rig into an very sudden and violent sway that was only saved by the factory sway control. There was absolutely no way I could have saved it. I would have wrecked for sure if not for the factory sway control system fully engaging. My hands never left the steering wheel and I regularly practice the trailer brake grab.

Though I am adamantly apposed from a personal experience/opinion standpoint if you are going to insist, install the factory tow/sway control system then have Andy at CANAM reinforce the hitch (he did my ML350), and use a Pro-Pride with 1,200 - 1,400 pound bars. I went Pro-Pride after I almost wrecked above. There is no comparison to the safety and stability period. Even after buying the 2015 Chevrolet 2500 HD I still use the Pro-Pride.

All is well until you are put into emergency situations. With the ML350 pulling the 30' I never felt safe. I will take the security and safety of my larger TV with the larger trailers. It has been repeatedly demonstrated over the years that you can pull an airstream with anything. Does not make it safe for you or often more importantly others.

VW Touareg TDI 2015 driver assist features when towing

Getting a 2015 VW Touareg tdi to pull possible 5500 pound TT. Concerned about loss of driver assist, safety lane changing, and Adaptive Cruise Control features when towing. Does anyone have experience using these features while under tow? Thanks

KayakBuddy,

First: Make sure you have one of these: https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1

Second: Make sure the receiver is actually installed (my Porsche did not have it)

So, I just towed with my Macan and it also turns off all those items. However, I never used the lane change assist as I KNEW it wouldn't take into account my Airstream. I had extended tow mirrors and they were life savers. I really want the camera for the back of the Airstream and am still researching.

Adaptive Cruise Control. I didn't once use my Cruise Control while doing my first tow so I cannot respond. My understanding is you will STILL have cruise control, just not the adaptive. If you get the plug in I linked above, it will automatically adjust your cars electronics, even if you don't have the tow vehicle attached. This will allow you to understand how the car will respond.

The interesting thing that surprised me (and I need to get more tow experience with my car to research) if that I had the Prodigy RF Brake Controller. When I turned on my emergency flashers, the Airstream brakes came on to slow the vehicle (brake start/stop as if you were doing a controlled brake slow).

Not sure if any of this made sense or helped.

I tow with a 2017 Audi Q7, which is a close cousin to the VW Toureg.
Most of the Driver Assist features still work when towing. One Driver Assist feature that does not work is the Pre Sense Rear system for detecting collisions from the rear.
The Lane Changing safety feature does not work when towing. Too bad, at it is awesome. Never before had it on a car.
The Adaptive Cruise Control does work when towing. Again this is awesome, and again, none of my previous cars had this.

I have the 2014 TDI version. Extended mirrors is/may be required for some state and that will be the only driver assist along w/ your co-pilot in the passenger side As for the other features, I can't comment since this is my first TV that I've owned that has so much bells and whistles

I tow a 20 ft Cloud rated at 5500 lbs with a 2016 Touareg TDi. Lane assist is the only feature that is disabled during towing. You will be impressed with how your Touareg handles adverse conditions. As already suggested, be sure to use a WD hitch and sway control when not traveling local, and put transmission in sport mode.

2013 VW Touareg TDI Prep Package

When I check VW website on hitches everything says don't do anything until the 1D6 trailer prep pkg is installed. My vehicle data sheet says the 1D8 trailer hitch prep pkg is installed. Do I really need to have the 1D6 or dealer equivalent installed? I read in one thread that the 1D8 is all you need. Any other options besides VW dealer installation?

I am planning on towing a 22 Ft. Bambi.

Thanks,

Why use a WD hitch when the Touareg manual specifically says not to use a WD hitch? I tow with a Porsche Cayenne which shares the same chassis as a Touareg and would never consider WD or Sway control. That's right, I tow my 26ft Overlander with just the ball and chains with zero issues. My Cayenne is the Chuck Norris of tow vehicles. It's so stable that the semis shake when they pass me.

I don't know what your tongue weight is, but if it is 450 lbs or more you will benefit from a properly set up weight distribution hitch. For most modern AS trailers it is strongly recommended, the vast majority of people with these tow vehicles use WD for a reason - the handling dynamics of your Cayenne will be greatly improved. Sway control is a matter of choice but it is also strongly recommended. You don't need it until you do......

Happy camping.
