Any progress on the LED trailer light issue?
OK, I know very well Porsche hasn't admitted there's anything wrong with their setup, I was wondering if any aftermarket supplier has come up with an adapter that allows us to use U-Haul trailers (w/ LED lights) with these things? I thought there was a 7 pin round to 4 prong flat that had some resistors built in that allowed the lights to function. I checked 3 auto parts stores but none knew what I was talking about, neither did U-Haul.
I tried to rent a trailer at U-Haul this afternoon, trailer had LED lights. The brake lights worked fine but the tail lights and turn signals just blinked real dimly the whole time (even with the P!g turned off and key removed the trailer lights continued to blink rapidly). Couldn't use the trailer because I'll be driving about 1400 mi., much of it at night.
I know we have several trailer light threads, I was hoping there was some new info.
Fortunately I have my trailer (w/ std. bulbs) that works fine, it's just bigger and heavier than I need for this trip. Oh well, at least I have a backup.

Clarification please; I installed a seven blade connector on my '13 CD. You wrote "seven pin" connector. Both are round. It makes a difference when you're shopping for an adapter. I also have a 7-blade to 4 pin adapter. That said, none of my 3 trailers have LED lighting, so I can't help in that area. Sorry.

Bill, I installed a Pollak 7 way blade connector on my 2011 Cayenne. Can't guarantee it would be the same for your '06 but I got the info on the Pollak from a thread that was referencing earlier Peppers so I think it would work.

Then I bought the adaptor in the pics below. It's made by Valley but was available through a VW/Audi dealer; can't recall which one. I do remember that the dealer web site listed part numbers for Tourareg and Q7 models which are interchangeable with the Cayenne. I've pulled equipment rental and U-Haul trailers with both regular and LED lights with no problems. It even deactivates my backup sensors and activates appropriate warning lights in my instrument display.

I tried the same adapter on in my '10 and it does not work with UHaul LED light trailers. For whatever reasons, the brake lights didn't work. Maybe it now works for the newer models.

I'm thinking about getting this one:

Note that it also comes in a 7-4pin

This adapter works. I have it on my '11 CS. I trailer a Trailex with LED. Brake lights, back up sensors, etc. all work fine. However, if the Cayenne is off and the trailer is still plugged in, the lights on the trailer will intermittently blink. My solution is to just unplug the trailer when parked at the track or elsewhere. I doubt the battery drain is very much, but I do it anyway.

Having a heck of a time finding the Valley above but I did find this site, maybe the brand is Valley, we'll see. Ordering it now.

Looks similar Bill, hope it works for you. When I bought mine over a year ago I also had a heck of a time finding the Valley piece. Word at the time was they were moving their manufacturing plant and product distribution was disrupted, but I was able to eventually find a VW dealer that stocked it under their part number. I would have thought they would have had it resolved by now, assuming they are still in business.
I haven't noticed that. I'll have to pay more attention next time I trailer.

Lewis--Glad to see that you finally solved your Cayenne trailer issue--No Cayenne, No Issue!

Clearly there can't be a solution where there is no problem....there wasn't even a trial
