  1. Thanks. I stopped by the dealership and confirmed that the pre-wiring for the brake controller still comes with the trailer option in the configuration of a car order. The dealership does not do the the installation of the brake controller. They sent me off to a trailer place. It turned out that the trailer place would not touch any Porsche because of issues of updating the system. They use a basic Draw-Tite controller. All this raises a basic question - what is the point of a brake controller? If one were towing just occasionally and over short distances, is the brake controller necessary?
  2. Thanks again. The part numbers I got are: ZVW808007 @ $74 HOP47355 @ $25 The second one is likely a Hopkins part, not sure about the first. Another question: Is the brake controller part of the factory installation? If one were to attach a trailer that requires/has brakes, with the appropriate seven-pin connector, is everything good to go?
  3. Thanks. After posting my question, I got under the car and could now see a black rectangular plate fastened with four screws to the right of the hitch (looking up from below, facing the rear of the car). The plug from the trailer wiring probably goes into whatever is beneath that plate. Since it is a factory install, I am guessing the programming is already done.
  4. I bought my 2011 Cayenne S Tiptronic with the trailer hitch pre-installed. What else do I need so that I can tow a trailer? In these forums I found a suggestion to stay with the Porsche hardware because after-market hitches cannot take full advantage of the towing capacity of this vehicle. Contacted the parts department at my dealer and was told there is no Porsche part for this. Further, that I could get the wiring connector from the Audi dealer, and the trailer people would set me up with the right ball carrier and ball for my trailer. Something does not sound right - I asked the wrong question or received an incorrect answer. I do not have a trailer and the idea was to have a set-up just in case a need came up, including helping somebody who might be stuck somewhere. Suggestions? Thanks!
