Right turn signal makes both front turn signals blink pls help

[Audiandchill]

Hello everyone, I have a weird problem with a new to me 2012 Audi A6 Prestige, its equipped with the xeon adaptive lights. I have a very weird issue, when I turn the right signal on it makes both front turn signals flash as if my hazards are on, if I turn the left signal on nothing in the front flashes. Everything else on the lights work perfect. I currently don't have a scanner that can print a full log so I will list codes below.


DTC_02895: Supply Voltage for left LED-module for daytime running light and parking light

C108515: Control of servomotor for headlight range control on the left -v48 short circuit to plus or interruption

DTC_00230: transmission park selector switch (F305)

DTC_01316: control unit breaks

U0001: CAN bus drive

DTC_01516: Terminal 30 left

I will try to get VCDS soon so I can show the entire log, I tried to do it with ODIS but never works. These are the only codes I have, I know that the battery was a little low when I purchased the car and there was a billion codes for no communication and low voltage, I charged the battery to 100% and cleared codes and these are the only coded that came back. Oddly enough when I bought the car the right turn signal flashed as normal, and the left did nothing. Then randomly the next morning it started to do this. I checked the fuses and they are all good, I couldn't find a diagram for the relays so if anyone can point me to the right direction that would be great, wires all look good as well. I even opened the light to check the v48 motor and it looks good, the wire going to it looks fine. Any help/advice is much appreciated, thanks!

The first thing I'd do is replace your battery. Strong chance it's not holiding a complete charge. Always the first place I look when "wierd" electronic gremlins are occuring. You will need to program the new battery to the car. Then, erase the codes and move on from there.

Funny timing but I just replaced battery, coded, & no luck, I noticed that the rearview mirror is aftermarket and doesn't have anywhere to plug the connector, doubt thats the cause of my issue though. I checked wiring from the connector again and a few of them were pinched, I spliced them with heat-shrink tubbing and still no luck, I may have to buy a new harness, any idea where the harness leads too after it loops under the airbox?

Is there any chance a faulty hazard switch could be my issue?

Does anyone know what color wire controls the left front turn signal? & Which color wire controls the v48 on the left side?

I have the headlights that look like this

Anyone ever experienced this? I cant find anything online, the wiring is fine, when I click the left turn signal nothing happens in the front but lights in the back all flash accordingly, when I click the right turn signal both of the front lights flash as if my hazards are on. Inside the car on the instrument cluster the turn signal indicator blinks fast, Im located in Loudoun County if anyone on the forum is in the area, thanks guys
