I've searched hi & low and can't find the definitive answer for this - my auto lights are too sensitive / coming on when its still daylight.
I've also had a good look around VCDS and have found the following settings (8P3/2009 A3 with Bi Xenons & Auto Wipers / Lights):
09 Central Elect. > Long Coding > Component: Component: REGENLICHTSENSORH04 0003 > Coding:
Byte 0, Bit 3-4:
00 Light Activation Threshold normal
08 Light Activation Threshold earlier (+20%)
10 Light Activation Threshold earlier (+40%)
18 Light Activation Threshold earlier (+60%)
Am i correct in thinking that this will make the light sensor more sensitive? (the opposite of what i'm trying to achieve)
Byte 02, Bit 0-7:
Here are various options relating to glass and vehicle type - does the higer % make the sensor more sensitive or less sensitive?
I also read somewhere that adjusting the Intermittent wiper setting on the wiper stalk increases / decreases both rain senor and light sensor sensitivity - would this be true on my 2009 A3?
