I've been trying to do some research into improving my DRL but so far I've had no luck!
I have a set of these: AU-A3-5100.jpg
For the most part I am really pleased with them! they look great even when switched off! the problem I am having is the LED strips inside the headlight are powered by the sidelight instead of their own separate power which means if I set them to DRL via VCDS the dipped beams have to be on aswell which looks a bit naff so I have to do the old fashioned manual switch.
The other problem is when I indicate they do not dim which isn't so much of an issue as the indicator is clearly visible however I believe for MOT I need them to! I do not have an option in VCDS to add the dimming (can I update my ECU?) My solution would be to buy a separate DRL controller there are tons on various auction websites and they seem to work quiet nicely however because these lights are my side light if I disconnect the LED I get a lovely blown bulb error.
Can someone provide a wiring diagram for the headlight? I would like to place a resistor or connect a hidden 501 to trick the car into thinking the side lights are powered whilst running the LED from the seperate controller.
Any other ideas would be welcome!
