Right Fog Light LED DRL Flickering

[TJSparky]

Has anyone had any issues with the DRL LED fog lights flickering? It is just the DRL LED beam in the right fog light that is doing it. I tried unplugging it and plugging back in with no positive results. May end up taking it to the dealer as I think it’s the light assembly itself but just wanted to see if others experienced the same thing.

Have you done the Forscan mod to increase the brightness of the DRLs?

 

[TJSparky]

Yes I did. I just turned them back to stock to see if that stops the flickering. Will report back in a bit.

Are mods done via Forscan traceable by a dealer?

So I changed the DRL values in Forscan back to stock brightness and let it run for 5 min.. no more flickering that I can see. I will watch it for a few days to see if that actually fixed it or not.

So there are 2 ways to do the drl forscan mod. The one you did which I think forced it to 100% and another that allows you to set the "dim" percentage to a higher value. Many who had the flicker issue changed their value to 75% or so and the flicker stopped. They also reported no observable difference in output.

I'll see if I can find that main thread. I still plan on reverting mine (the same one you did) and doing the alternative as I feel it's the better approach.

I believe this is the thread. Read through it.

Edit: looks like the first post on that thread was updated with the alternative method as well. Less reading for you ?

OK... This is interesting as I was using the original BCM change

726-42-01 0303 - 0101 - 057D Changing to 0202-xxxx-xxxx

I appreciate the info as this appears to be what I have been experiencing.
Going to try the 75% change and see if that helps

EDIT: 75% still caused flickering for me but 50% seems stable.

I appreciate your help on this.

Curious is there any diff on the 2019's cause I changed mine to extra brightness and I have not had any issues at all!!

I believe in the 13th gen at one point they were 100% brightness from factory. They got complaints and adjusted it down. My current theory is that the 13th gen hardware is made to ensure support for 100% brightness, but since the 14th gen was never designed to operate at 100% the hardware may or may not work as expected.
