Does anyone know if we can control the brightness of the LED DRLs via Forscan. I enabled the parking lights, but that dims the LEDs anyway to make them brighter?
I found this but I don't understand what I'll need to change the values to.
edit: i figure it out and it doesn't seem to change anything... not that I notice anyways, and the default is already set to 100% (xx64 xxxx xxxx)
I found the solution if you scroll down
The DRLs dim when the lights are on to reduce the glare to oncoming drivers.
He wasn’t asking why they dim, he was asking if there’s a way to prevent them from dimming. FWIW, this is up to the manufacturer, many drl led’s are much brighter than ours, whether headlights are on or off. My wife’s X6 is an example.
OP. Interested in this as well. The last Audi I had I was able to change the led drl brightness with VAGCOM (similar to Forscan). There was a 0 to 100% adjustment. I haven’t been able to find anything. I fooled around with the setting Scott mentioned but it didn’t do anything. Let us know if you figure it out.
I also found this but I'm not sure if it will work.
726-45-01 xxxx **xx xxxx DRL Lamp Mask Cfg *allow all DRL choices=7F
726-50-01 40BE DRL - Low Beams and Dedicated DRL (this may get rid of flickering for LED conversions)
"You need to enable all DRL choices at 726-45-01 for these to work"
Okay I figured it out by looking at the as-built sheet from a Super Duty with LED lights. Super Duty trucks keep DRLs at full bright when low beams come on so I compared the BCM to my F150 and figured it out.
Under BCM - DRL Position Lamp Cfg.
Should look like this:
726-29-02 0100 0001 005A
I found this but I don't understand what I'll need to change the values to.
I do not know if this will do what you're looking for, but likely those two ** for the percentage are in hex. What does your as-built value have there? Find a hex to decimal number converter on line and see what percentage it is. If it isn't 100% try setting it to 100% in hex. Using this converter it would be a value of 64.
