Hi everyone! I have imported Golf 7 GTI from USA to Europe and i have a problem with changing tail lights to european one. My car has the normal bulb lights. I have already changed outter lights to european ones with orange turn signals on the bottom. Can you help me finding the way how to make them work properly? Also how to install rear fog lights on us version? My car is equipped with front fog lights and i have already changed light switch to european one.
Thanks in advance!

Hi - interesting project, thanks for posting. So - need more information, please: as you will be well aware, the wiring loom for the rear tails on a mk7 is different for NAR (North American Region) models because the "yanks" have multi-purpose stop lights. When you "changed outter lights to european ones with orange turn signals on the bottom" - did you run 2 x wires to the BCM? If so, did you use pins A60 and C31?

Hi Don, I didn't run any wires yet. I have found some information on another forum that it could be done without it. "You have to re-pin two wires at the connector on each side. Pin 1 goes into Pin 3 and Pin 4 into Pin 1. After that you have to do some re-coding: add braking to Leuchte27NSL and disable Running/Brake light function from Leuchte20BL and Leuchte21BR." But when I made it this way, turn singals are flickering when i hit the brake. On another forum i found information that "signals will always flicker on braking as channels 20 and 21 want to be brake lights." If you have some ready and working solution i would be greatful if you would share it with me. I really want to start driving this car

Given my location in the very deep south, you will appreciate that I don't get to see many NAR model Golf mk7s down here!!
Basically, it's ostensibly a question of what type of effort (and how much effort) you are prepared to put into your project: it's a trade-off between the following:
- a fairly simple coding change task if you are prepared to put-in what's a non-trivial effort in installing 2 x wires back to the BCM to connect to the turn-signal lamps (this is the factory solution). I would first check that your NAR hex09 module has the A60 and C31 pins populated if you opt for this approach.
- a much more complex coding exercise for the simpler task of swapping pins at the connector on the tails
Of course opting for option II above means that you face the type of problems that you have observed (flicker) because of the "novel" assignment of lighting function into Leuchte-sets that were never contemplated, or designed by VW engineers.
I guess that another approach might be to use parts of the NAR cross-wiring harness that is used for retro-fitting LED tails on incandescent tails. These harnesses (and the coding changes for these harnesses) solve exactly the same problem in that they separate out the turn-signal function into specific lamps from the brake light. Of course a cross wiring harness does more - but you could just not use the wires in the harness that parallel the inner and outer turn signal LED lamps.

Okay, i think i will just go for running the cables from BCM. It seems to be the best solution. Is it possible that my BCM doesn't have pin A60 and C31? Did you heard about something like that?

Did you heard about something like that? rafair32: hmm..... the decision is entirely yours! This is the type of BCM that will be installed in the car:
There are 3 x types of BCM:low medium and high - I'm not sure which is installed in your car. As you will appreciate, we don't get to see many NAR model mk7s down here in the very deep south (Australia)!
The fact that US doesn't use separate blinkers for their incandescent lamps and the fact that NAR is a specific model means that there may be versions of BCM that specifically omit the pins. However, NAR model mk7s with factory fitted LED tails do require the A60 and C31 pins - so that's positive!
In any event, my general recommendation for anyone intending to connect new wires to the A, B, C sockets in my picture is to always check that the mating pin is actually populated on the BCM housing BEFORE starting the project. I make this suggestion because if the pins are absent - the project becomes more complex: changing the BCM is a non trivial exercise because Component Protection measures need to be resolved which means a trip to your local dealer.
My hope is that after you un-plug the A and C sockets, you will eyeball the pins in question - this will confirm the scope of the project.
