Hello.
I have a 2007 Octavia II RS TDI. I'm a bit annoyed by the tunnel light function. It turns on even when you pass under a short bridge. While the Xenons are "gently" ramped up, all those ignitions are surely not the best thing for the bulbs.
Can the connection time be increased in the control unit so that it ignores the short connections?
Best regards, Limpi.

I know it's not a real answer:
But.
That's exactly why I turned off all those fun lighting features.
"Leaving home" is especially annoying when you park in a garage. Then the xenon headlights always turn on for the 5 meters you need to drive out. Transparency, Teamwork
... there was another T.
I don't know what the f*ck it was.

Which 09 body control module (BCM) do you have?
I should have a 3C0 937 049 xx checked and adjusted.
A008,0,Assist driving light.
A008,5,Assist driving light.
A008,6: This channel allows for adjusting the delay time for...
A008,7,AFL (Auxiliary Lighting) can be turned on/off.
A008,8: The on/off process will then be delayed accordingly.
A008,9,
A008,10, Range: 0 - 255 seconds.
A008,11, Factor: 40
A008,12, Example: 10 (seconds) x 40 (factor) = 400 (input value) Transparency, Teamwork

I don't know what the f*ck it was.

Hi.
Yes, I have also disabled "leaving home" and "coming home" - I also park in a garage - Thank you for the parameters. It should actually be the correct control unit. A friend has a VAG-COM, so I'll stop by and check it out  .
Best regards, Limpi.

I extracted the parameters from the label file.
Perhaps it can also be done using "long encoding".
