LED DRL Dim when Turn Signal Active
Thanks to CrzyP at

WARNING: I will not be held liable if anything occurs when attempting to change anything in the VCDS software. These instructions are created to the best of my knowledge and are as accurate as I can make them. Please be careful before you save your settings and always run Auto-Scan before any changes are attempted.

Changing Instrument to Rest of World (RoW)

Load up VCDS, click on the Select button under Select Control Module

Click on the 17-Instruments button

Click on Coding- 07 button

Click on the Long Coding Helper button

In Byte 0 under Bit 4-7, click the drop-down menu and select 10 Country: Rest of World (RoW)

Save your settings.

NOTE: This will change some things such as chime when door is open, light sensor sensitivity and others to non-USA/Canada requirements/recommendations. I am not sure what they are, so please use caution.

Things I've noticed on my 2012 Canadian Spec GTI is the following:
1) When you forget to turn off your lights when your key is out of the ignition and the door is open, it only chimes 4-5 times or so and there is no more chime. The default is the chime is continuous until you shut off the lights.

2) The RNS-510 system does not shut off when you turn off the car with the keys still in the ignition. This will not work with the RNS-315 since it is controlled by another module, I believe.

3) The light sensor sensitivity is greater than default. I am not sure if this is a placebo effect or not, but it is something I've noticed.

Changing DRL Inactive when Turn Signal Active

Load up VCDS, click on the Select button under Select Control Module

Click on the 09-Cent. Elect. button

Click on the Coding - 07 button

Click on the Long Code Helper button

Click on Byte 15 and check mark Bit 3 - Daytime Running Lights (DRLs) inactive when Turn Signal active

NOTE: Your LED DRLs will dim when the turn signal is active and turn back to full brightness when turn signals are inactive. However, this will not work if you are on parking lights mode (since during parking light mode, the LED DRLs dim anyway).
