Hello,

I have Audi A5 2016 cabrio and the LED on right side headlight is not working. I know there's an issue in the inside of the headlight, because I've tried connecting left side headlight and it worked. Tried changing LED module, doesn't work. It means there's probably a broken wire somewhere in the headlight or sth. Does anyone have a wiring diagram of it ? Part number: 8T0 941 032 C

When you say you changed the LED module, which module did you change? There is a LED Ballast module then at the outside edge on the back of the headlight there is a LED bulb module (contains and upper and lower LED bulb). Audi does not sell this bulb module separately but they are available on Ebay. Occasionally they fail completely, sometimes the LED just dims or puts out a yellowish light. What you see from the front of the headlight is just a clear plastic fiberoptic tube.

You'd need to bring up the wiring diagrams document. If you don't have one for your car, along with all the workshop manuals for it, from Audi from erwin.audi.com, you can try and use the online copies at cardiagn.

"the LED", you mean the DRL? The LED driver module is just that, a driver. The LED element itself is in the headlamp. There are threads out there showing disassembly of the B8.5 HID headlamp for replacing the yellowing DRL LEDs. So you might find that useful too.

Thank you for the replies. Maybe you have the pinout info for this headlight ? It has 11 pins. I want to check if the the LED bulb module is even getting the voltage.
