I've had a look at my own CAFD for the FEM and at the moment that setting of MAPPING_TAGFAHRL_V_L_OFF MODE is Level_nr Wert=0 now there are some other comments :

Comment = PWM-level (1-5) to activate in OFF-MODE of mapping function (e.g. to activate in off mode of indicator) 0 no special PWM level in OFF-mode = valid coding range: 00-05
level_nr (level n) = 00

Am I correct in thinking the 00-05 tie in with PMW_LEVEL_1 to PMW_LEVEL_5 above?

Correct but I'm not so sure about it. It sounds easy in theory but really isn't. Increasing the intensity for the running light functions was because everything was mapped. Really have to think this one through. If only there was a DRL_BLINKEN setting mapped out for the variant...thinking cap on.

I'm happy to activate to see what happens (if anything) but there is also:

MAPPING_TAGFAHRL_V_L_DIMMED

And the options are:

Comment = Activates/deactivates the option, to switch on or switch off this function with dimming. (Use standard dimming: switch on: 1, 3 s; switch off: 2, 6 s.)

Is that worth a look too or i it for something completely different?

The inverse on a 2er AT (DRL dimming with indicator removed) was just sorted and took about 45mins. It was BLINKEN in FLE's that made the change but the settings are quite different.

Values for both FLE ECUs and the settings are:

DRL_Idx
F045Wert
Werte=04, 04, 04, 0B, 04, 0A, 04

BLINKEN_Idx
Unknown
Werte=04, 04, 04, 10, 04, 04, 04 (NEW = 04, 04, 04, 0F, 04, 04, 04)

BLINKEN_PO_Idx
F045Wert
Werte=04, 04, 04, 04, 04, 04, 04

Brilliant Job

I've noticed you only have 7 bits whereas my F30 has 10 bits

These are my default values for each set in my FLE:

DRL_Idx
F030Wert
Werte= 00, 00, 00, 00, 00, 00, 04, 00, 00, 00

BLINKEN_Idx
F030Wert
Werte=00, 00, 00, 00, 00, 00, 00, 09, 00, 00

BLINKEN_PO_Idx
F030Wert
Werte=00, 00, 00, 00, 00, 00, 00, 09, 00, 00



The correspondence of each of the 10 bytes in the word to a specific LED or group of LEDs is not fixed, but determined by the functions LMxx_Name (where xx=01,...,10) in Group 3006 Led1. Each of these can take one of the following values: 1 = LB1, 2 = LB2, 3 = LB3, 4 = HB1, 5 = HB2, 6 = HB3, 7 = DRL1, 8 = DRL2, 9 = DRL3, 10 = CL1/ML1, 11 = CL2/ML2, 12 = CL3/ML3, 13 = SML1, 14 = SML2, 15 = SML3, 16 = FRAZ1, 17 = AZL1, 18 = AZL2, 19 = AZL3.

I need to try and translate your mappings into mappings for my car.

The specific attributes that correspond to each Setting Index are defined in group 3005 LmmX. For example, the first 7 functions in LmmX (which correspond to Setting Index 0) are

LmmIdx00_Intensity
LmmIdx00_TimeOn
LmmIdx00_TimeOff
LmmIdx00_Priority
LmmIdx00_RampType
LmmIdx00_ErrorImpact
LmmIdx00_Active

What are the values for the hex 04, 0A, 0B, 0F and 10 on your car? (These last two are the most important)

Yes, I've managed to sorted it out

Ok, the mappings in the FLE maybe different of each country and also if you have standard LED or Adaptive LED, but the principle will be the same in each case.

in the FLE (CAFD_0000243C_XXX_XXX_XXX) open 3006 Led1

Each of these can take one of the following values: 1 = LB1, 2 = LB2, 3 = LB3, 4 = HB1, 5 = HB2, 6 = HB3, 7 = DRL1, 8 = DRL2, 9 = DRL3, 10 = CL1/ML1, 11 = CL2/ML2, 12 = CL3/ML3, 13 = SML1, 14 = SML2, 15 = SML3, 16 = FRAZ1, 17 = AZL1, 18 = AZL2, 19 = AZL3.

This will correspond with the 10 bit setup for your car and in the case of my EU Spec with standard non adaptive LED's they correspond to the following:

LM_ID_LT01 F020Wert = 01 LM01 F030Wert = 04
LM_ID_LT02 F020Wert = 02 LM02 F030Wert = 02
LM_ID_LT03 F030Wert = 03 LM03 F030Wert = 01
LM_ID_LT04 F020Wert = 00
LM_ID_LT05 F020Wert = 00
LM_ID_LT06 F020Wert = 00
LM_ID_LT07 F020Wert = 07 LM07 F020Wert = 07
LM_ID_LT08 F020Wert = 08 LM08 F020Wert = 10
LM_ID_LT09 F020Wert = 00
LM_ID_LT10 F020Wert = 00
1 = LB1 2 = LB2 3 = LB3 4 = HB1 5 = HB2 6 = HB3
7 = DRL1 8 = DRL2 9 = DRL3 10 = CL1/ML1

So, Light Module 1 is the High beam 1, Light module 2 is the Low Beam 2 Light module 3 is Low Beam 1. 4,5, and 6 are not mapped to anything. Light module 7 is the DRL and Light module 8 is the CL1/ML1 or the turn signal eyebrow. Again bit 9 & 10 are not used.

Now, each one of those 10 bits can be dimmed, turned on or off or even ramped from dim to bright depending on the value of the bit corresponding to that group.

This is sorted out buy the values in group 3005 LmmX. For example, the first 7 functions in LmmX (which correspond to Setting Index 0) are

LmmIdx00_Intensity
LmmIdx00_TimeOn
LmmIdx00_TimeOff
LmmIdx00_Priority
LmmIdx00_RampType
LmmIdx00_ErrorImpact
LmmIdx00_Active

For a EU Spec car with non adaptive LED's the 10 bit mappings for the settings in 3004 LummB are as follows (Numbers are in decimal instead of HEX) and in the smaller table are the settings for 3005 LmmX :




The key values are in BLINKEN_Idx and BLINKEN_PO_Idx, Although I think the BLINKEN_PO_Idx doesn't do anything.

The standard bit values (EU Spec non adaptive) in 3004 LummB are as follows:

BLINKEN_Idx
F030Wert
Werte=00, 00, 00, 00, 00, 00, 00, 09, 00, 00

BLINKEN_PO_Idx
F030Wert
Werte=00, 00, 00, 00, 00, 00, 00, 09, 00, 00

The key bits above are bit 7 (The DRL) Bit 8 (The CL1/ML1 Turn signal Eyebrow)

At the moment they are set to 00 and 09 respectively. So, when the turn signal is on, nothing happens to the DRL (00 has such a low priority it does nothing) and the Turn Eyebrow is on 100% intensity (see LmmIdx00 and LmmIdx09 in the smaller lower table above)

I got the idea it was a simple as altering bit 7 to 05 ( See LmmIdx05 in the smaller lower table above) which is used in POLI1_idx, POLI2_idx and POLI3_idx to dim the DRL to 46% (HEX 2E) when the headlights are turned on. This didn't work

Here's what to do:

The key is the priorities for each of the LmmIdx settings. The higher the value, the higher the priority over all other bits in the group. If you look at LmmIdx09 the priority is 1 which means it overrules anything else and LmmIdx05 only has a prioriy of 3 making it lower priority. Even lower than the standard setting on the DRL in the big table which uses LmmIdx04, which also has a intensity of 100% (HEX 64) but a priority of 2. That trumps priority 3 and keeps everything at 100% intensity.

So what I did was make a new LmmIdx10 (HEX 0A), that was not being used anywhere else, with an intensity of 46% (HEX 2E) but a priority of 1. I then replaced the bit 8 values with LmmIdx04, which is still 100% intensity but with a lower priority of 2.

So the new Working Codes for DIM DRL on Turn for a EU spec with Standard non Adaptive are as follows:

BLINKEN_Idx
F030Wert
Werte=00, 00, 00, 00, 00, 00, 0A, 04, 00, 00

BLINKEN_PO_Idx
F030Wert
Werte=00, 00, 00, 00, 00, 00, 0A, 04, 00, 00

And the Lmmidx10 values, in 3005 LmmX are as follows:

LmmIdx10_Intensity 2E
LmmIdx10_TimeOn 00
LmmIdx10_TimeOff 00
LmmIdx10_Priority 01
LmmIdx10_RampType 00
LmmIdx10_ErrorImpact 00
LmmIdx10_Active 00

Remember to code both FLE modules

I need assistance from owners of :
EU Spec With Adaptive
US cars with Standard and Adaptive LED headlights

I will then create a simple table for each variant.

I'll post a video of it working later on but I hope everyone can follow my ramblings above.

Thanks must go to dmnc02 and Zidonuke from Bimmerfest forums as this is based their work and thanks also to lemetier as he also guided me too.

[Gabreigns]

Brilliant work! Can't wait to see the video. Now if only I can decipher what you said here to a US spec car with xenons.

[jaddie]

Same here haha, that is utterly fantastic work and I can follow along with pretty much most of what you are saying and get it from a tech perspective, but its a bit difficult for me to take that and then work out all the things I would need to do for mine for example, a 430d with the adaptive leds haha

If you want to send me the .ncd files from one of your FLE 's I could probably work it out quite quickly.

That would be super. I am sending you the .ncd via PM.

[stu14t]

Here goes with the Video.

Didn't work out too well as the camera sees the oscillation rather than the DRL dimming. But you get the idea I hope:

I am not sure if I am being daft, but I was expecting there to be an ECU called FLE, there doesn't seem to be on my 430d?

Only with LED Headlights.

[jaddie]

I have the adaptive LED headlights, the only part I can find so far is the dimming values in FEM that stu14t mentioned before, but is there any other names those ECUs might go by?

[stu14t]

Can you provide a screenshot of your SVT Screen like the one below:

This is my car and the two FLE's are highlighted.

[jaddie]

Here you go

[stu14t]

Can you look in the LHM modules as see if they look like this:

[stu14t]

What is the CADF file name for the LHM modules (should be both the same)?

[jaddie]

Unless I am being daft, I can't see that sadly!

[stu14t]

I think this is the older adaptive LED found in the 5 & 6 series. The system has changed in the LCI F30. I suspect it will in the when the LCI F32 & F36 come out, the system will change then.

Unfortunalty I don't think my mod won't work of a 4er yet.

[stu14t]

Can you look at the TMS modules too?
