VW T5 Interior Lighting Dimming Levels

Hello,

I'm currently trying to get a T5.2 Climatronic head unit working without connecting it to a vehicle.
Turning it on works (ID 0x575, send ignition on signal).

Which ID controls the brightness of the lighting?
0x5DD? But how exactly? Nothing changes when I modify byte 3.
(IDs are listed below)

Thanks and best regards,
Simon.

Perhaps it's because your database is for the Golf 5, but you have a T5?

Hi!

The ignition IDs are also the same . I just tried it - nothing happens.
That's why I'm asking, maybe someone knows the correct ID for a T5.

Regards,
Simon.

I can't open your CSV file, but please take a look at the ID.

0x635 3 37 00 00 -> 37hex = 55dec = 55% illumination.
