First of all I need to say a big thanks to jaddie as he allowed his car to the the guinea pig for this mod.

Now the 4 series with adaptive is slightly different. They don't have two FLE's but instead have two TMS modules. This is from the adaptive LED used on the older 5 and 6 series.

Within the TMS modules there is a similar setup to control the LED modules of the indicator, the orange side markers (US Cars Only), the eyebrow's and the DRL rings for example:

3005 Leuchtmittelmatrix 1, F8
Tagfahrlicht (daytime running light)

It seems that the 16bit sequence is actually split into 4 groups of 4

00 04 00 00 00 04 00 00 64 03 00 00 64 23 00 00

The set in red controls the indicator
The set in magenta controls the little yellow side markers on US cars only
The set in blue controls the Eyebrow and..
The set is green control the DRL rings

The first HEX byte in each group controls the brightness. 00 = 0% 64 = 100% and I believe the second byte controls the priority over other lights. The other two I'm not sure but I think it may be TimeOn and TimeOff as with mine, where the welcome lights dim in and out.

To make the DRL's dim when the turn signals are on you need to change (EU cars only at the moment)

TMS > 3006 Leuchtmittelmatrix 2, F8
Blinken

To the following settings:
inWerte=64, 02, 00, 00, 00, 0F, 00, 00, 2B, 01, 00, 00, 2B, 01, 00, 00


There are issues over the eyebrow dimming too much but that can be changed by altering bit 9 (or the first bit of the third group of four)

Remember to keep within a valid HEX range of 00 = 0% to 64 = 100%

You will need to change these values in both TMS modules with the following CAFD:

cafd_00001082_0XX_000_00X.
cafd_00001083_0XX_000_00X.

Unlike the F30 LCI they have different numbers.
