I found on another forum that another security code is 02000, if 20113 does not work (which it didn't for me).

I also posted the following in the Carista thread on changing the LED brightness:

Looks like the latest version of Carista has the ability to change the nighttime LED lights based on voltage setting...

The default LED setting is 9% from what I've researched, and based on the voltage settings it looks like the settings are like this:

Brightness %Voltage
912.3
1612.4
2312.5
3012.6
3712.7
4412.8
5112.9
5813
6513.1
7213.2
7913.3
8613.4
9313.5
10013.6

I'm going to wait until sometime at night to go mess around with this and will let everyone know.

I'll give the security codes a try for my UK '08 and report back.

Are these codes constantly changed by Audi with their updates? Seems they work for a short time only.

Not sure about the lifespan of the security codes, but they sure are difficult to find.
I searched multiple Audi forums before even finding 02000.

Not an 08, but with the latest Carista Beta I was able to increase the DRL's on my facelift '15 Competition.

@thedragonseven

This is so useful. Thank you so much.

I can confirm 20113 works on 09- Central Elec. in my 2018 R8 RWS.

Thanks to this thread and that security code, I was able to Map out the module also.

I have managed to disable the front side markers but not the rear ones.
If anyone could please help me with this.

I confirmed 27971 was accepted on my 2012 V10 but when I went in to change the idle speed value it still said security access required.
