The good news is that troubleshooting brake lights that aren't. I have the oled tail lights working on my 2018 tts !! Brake lights are one of the most critical safety features that your audi tt has. I have checked the bulbs and they all seem to work. My audi tt brake lights are not working when using the brake. What could be the problem? So my brake lights don't work when i press the brake, but work when i arm my alarm system. Plug and play, as i was told, with no coding or modifications needed. The brake lights and taillights are often comprised of one light bulb, but they work differently. Replaced brake switch and brake lights still stay on what can i do.
I hope im explaining this right, but any ideas on diagnostics?
🙈 changed bulbs (standard?) and still no lights. Okay so few weeks ago my abs,brake,esp, brake fault warning lights came on and the whole rear left lights went out. Plug and play, as i was told, with no coding or modifications needed. How do brake lights work?
But will work when i turn on the hazard. This is a strange problem since essentially the connections for both lights come from the same source. I have the oled tail lights working on my 2018 tts !!
