2015 Wk2 Tow harness question

Hello all, I have a small problem and was hoping someone could clarify. We have a 2015 limited that did not come with the factory tow hitch, my father in law decided to put an aftermarket hitch but now wants the brake and turn lights to work, dealer wanted to charge him $300???!!! to activate this. Can anyone tell me what exactly needs to be done on a 2015? I know that earlier models needed some kind of "dealer enabled code" but I was under the impression that the 2015 comes prewired. Any help would be appreciate it as I am not willing to pay $300 for something that I can possibly do myself.
(By the way I have no idea about towing)

Re: 2015 Wk2 Tow harness question

I'm about to purchase a LGC Limited 4x4 without trailering pkg. and will be adding the oem hitch and connector. I also would like to know if getting the dealer to flash the computer system will get everything working correctly?

Re: 2015 Wk2 Tow harness question

So I've been reading a little more on this and it seems I can't avoid a dealership visit and it seems the coding shouldn't be more than $100?? Is this reasonable?
Thanks

Re: 2015 Wk2 Tow harness question

I have a 2013,
Added an aftermarket hitch and only needed the connector since the factory harness was there already. I made a bracket for the connector and used a couple pop-rivets to attach it to the hitch.

My dealer only charged me $30.00 for the 15 minutes it took to plug in and enable the wiring.

They all should do it for free.

I bought mine used with 4400 miles at a BMW dealer. So I should have mentioned my LOCAL dealer rather than my dealer.

By the time you add all that stuff in, you're almost at the level the two package comes to, especially if you're a good negotiator.

Plus, you won't be able to tow the shole load the vehicle is capable of when the factory package is included, due to the lack of the heavy duty cooling and electrical components along with other items. Even if you install the factory hitch, you'll still lose part of the towing capacity if it doesn't include the whole factory package.

After pricing out what is included, the tow package is actually a pretty solid bargain.

Exactly. I went looking for a Limited Ecodiesel with Tow Pkg. Was very hard to find that combination. Lots without the Tow. So I considered buying one without Tow, but when I figured out all the things that come with the package I decided it wasn't worth the hassle. So I got a summit that comes standard with Tow and 4 wheel self leveling.

If you have anything but a Summit then the differences are even greater. Summits come with the 4 wheel self leveling suspension already. But others like the Limiteds I looked at didn't have self leveling, and rear self leveling is part of the Tow. Also bigger trans cooler (std on diesel), bigger alternator, pre-flashed from the factory, etc. I've also been told that the dealer flash also changes the stability control to counteract trailer sway when the system detects a trailer plugged in. So adding all the correct bits on a gas GC to do it correctly is a lot more costly than getting the Tow on the vehicle.

And having towed 7,000 lb race car trailers more than 50,000 miles over the past 10 years, not having all the HD cooling, correct electronics for electric brake controllers, and proper suspension is not something I care to do. Towing a 3,000 lb boat or smaller trailer? Probably ok without the extra bits.

Re: 2015 Wk2 Tow harness question

The dealer we bought the WK2 from was supposed to have activated the trailer wiring when we purchased it. I installed the hitch the trailer plug later at home. I checked the plug with a trailer wiring tester and it is only lighting on the 12V pin. Also confirmed with a meter that I only see voltage between the 12V pin and ground. Can someone confirm that this means the dealer didn't activated the wiring like they said they did and charged me for it?

Just incase someone else runs across this same thing. Yes the purchasing dealer were lazy jerks, who did not enable the wiring via the sales code and computer flash. Fortunately our more local dealer took care of it and did not charge for it.
