Audi A4 B8 - daytime running lights

[jls398]

Heisann,

Jeg lurte på om noen hadde erfaring med hvordan en kan endre instillingene slik at en Audi A4 B8 får daytime lights også bak? Det funker jo fint fremme, men bak er det ingenting, og det er det jo på norske biler...

Mvh,
Jo

For å gjøre disse endringene må du ha tilgang på en vag-com kabel. Jeg har en slik selv som jeg bruker til koding av bl.a lys og utlesing av feil osv.

Om du har en slik kabel tilkobla må du inn på følgende meny:

Daytime running lights behaviour: Daytime running lights (DRLs) behave differently in different markets, for example the front LED light strips that accompany Xenon lights turn off or dim in some markets when blinking/signalling. Aerodave on A5OC.com has researched this and posted his experiences here: http://www.a5oc.com/forums/showthread.p ... index.html. In short, he reports that changing Central Electronics 09, Submodule 0 (Master Cent. Elec. box, rather than a slave module), Byte 3 (fourth from the left), Bit 7 (first bit from the left in the binary representation, bottom check box in the VAG-COM long coding helper) is the key. If set to 1, setting it to 0 makes the DRLs stay on when signalling. Thanks to Aerodave and please see the full thread for more! Note: Depending on market certain light configurations may be illegal to drive on public roads.

Aerodave - thanks! - sent this great list of additional bits you can toggle and turn to change the DRL behaviour.

For submodule 0:

Byte 02
bit 0 -
bit 1 - front side markers as DRL
bit 2 - headlights as DRL
bit 3 - fog lights as DRL
bit 4 - LED strip as DRL
bit 5 -
bit 6 - side markers as DRL
bit 7 - tail lights as DRL

Byte 03
bit 0 -
bit 1 -
bit 2 - LEDs remain at full brightness with parking lights
bit 3 -
bit 4 - Turns off DRLs when checked
bit 5 -
bit 6 -
bit 7 - Turn off LED-strip DRL with turn signal (dim LED if front side marker also selected as DRL)

Byte 10
bit 3 - Set to 0 to disable amber side markers (U.S. vehicles)
