Audi TT Coding Issues: Troubleshooting Guide

Hello, I'm writing in the forum for the first time and I hope someone can help me.

"When I activate the Night Light (NSL) as a brake light on my TT/8J, the right rear turn signal lights up when braking. A similar issue occurs when I code the NSL as a tail light. I've already searched for solutions on this topic, do you have any suggestions?"
"Furthermore, I would like to be able to activate the switches and ambient lighting when the switch is in position 0 (TFL Scandinavia), as so far I have only been able to activate the instrument lighting."
Can the brightness of the LEDs in the daytime running lights and parking light mode be adjusted? It is possible when the xenon headlights are activated.

And please note that this is only about my questions regarding what is legal and what is not; I am aware of that.

Thank you very much and best regards.
Ralf.

Hello Ralf,

1.) Perhaps the different taillight designs are related to different coding configurations. Have you considered this and searched for it in the AKTE database?

Regarding point 2: I have no idea. Perhaps try a different TFL variant sometime? I don't understand the purpose of illuminating the switches and displays during the day, so I suspect it might simply not be possible.

3.) Experiment with and adjust adaptation channels in the vehicle's onboard network control unit.

Best regards, Rainer.

Hello Rainer, thank you for your message.

zu1 ....the TT has 4 rear lights, 2 inside and 2 outside, some of which are combination lights with brake lights, and all can be individually adjusted in brightness. But how are they connected to the turn signals? ...AKTE???

zu2 +3 ....in the parking light setting, all the switches are also illuminated, right? If I could adjust the LEDs in the dimming function in this setting, I would have achieved my goal... (The idea is that I could still drive with 100% daytime running lights + rear lights + switch illumination even in twilight, without having to activate the Xenons every time)

Best regards,
Ralf

PS: I still have an error message that I can't delete, so I'll create a new thread about it.
