Question How to modify auto dimming side mirror values?

Hi folk,

my new LCI F11 does not dim the side mirrors in practice. This is the same issue as described here: http://f10.m5post.com/forums/showthread.php?t=784223

A few months ago I read about changing the intensity of dimming in percent somewhere but are not able to find it again. I guess it was a F30.

Does anybody know how to change the dimming values or where to look?

It can be enabled and disabled via FRM => ASP_ELEKTROCHROM_SPIEGELGLAS, but I don't know of a sensitivity setting.

THX, Shawn. I know about this. This does not help out because the intensity is to low. If I will find out more I will post it here.

Hello!

This evening I should get back my M5 (oil service) and the I will take a look on the moduls. My opinion is, that the dimming values (if they exist) for the mirrors could only be in FRM and/or JBBF. We will see.

Thanks, Oliver. I also guess it's in JBBF where you can adjust the RLS.

I found three settings under JBBF to adjust:

EC Faktor between rear mirror and exterior mirrors. It's INNENSPIEGEL (=rear mirror) / 32 * Factor. The max value is 39. Default is 20. I changed it to 39. (JBBF / 3080 InteriorMirror / CODDT_00_SCAL_DIM_ECR_LIN and JBBF / 3080 InteriorMirror / CODDT_01_SCAL_DIM_ECR_LIN)
My car has dark windows. I guess the factory setting coding was for cars without dark windows (ISP_HECKSCHEIBE = hell / dunkel). It was set to hell (= bright) I changed it to dunkel (= dark). (JBBF / 3080 InteriorMirror / ISP_HECKSCHEIBE)

Tonight I will test it and provide feedback.

Are you saying ISP_HECKSCHEIBE controls the dimming of the rear view mirror based on having light or dark rear windscreen, and then the side mirrors dim based on the rear view mirror's dimming and a factor set by CODDT_00_SCAL_DIM_ECR_LIN and CODDT_01_SCAL_DIM_ECR_LIN?

Is CODDT_00_SCAL_DIM_ECR_LIN the Driver's side mirror and CODDT_01_SCAL_DIM_ECR_LIN the Passenger's side mirror?

Hello, you can encode to be dimming outside mirrors?

My car comes standard without the extra.

Hi Shawn,

ISP_HECKSCHEIBE (HECKSCHEIBE = REAR WINDSCREEN) seems to controls the light sensors inside the car. The dimming of the interior and finally of the exterior mirrors are affected by the windscreen color. That's why the issue that the mirrors do not dim at the moment on many cars only seems to affect cars having SA 761 (dark rear windcreens).
The comment on this option says it controls a parameter set (for the interior mirror) based on the color of the rear windscreen.

In addition I increased the values for CODDT_00_SCAL_DIM_ECR_LIN (left mirror) and CODDT_01_SCAL_DIM_ECR_LIN (right mirror) which describes a factor for dimming the exterior mirrors based on the interior dimming.
It's the electro chrom factor between dimming the interior mirror and the exterior mirror (left or right). By default the exterior mirrors are dimming less than the interior mirror. I guess for dark colored rear windscreens the exterior mirrors should dim more than the interior because of the dark rear screen. So I increased it also.

I do not know right now which of the values are making the dimming working as expected. It's hard to test because one have to find a car with good xenon bulbs behind the car. And it must be dark outside without any or less lights in front of the car.

If I will find some time in January I will play arround with those values on a trip on the motorway. That's the best to test it.

Regards,
Fishermans

You need electrochrom (self dimming) interior and exterior mirrors to code the intensity of the dimming. (SA 430)

It's a special hardware. The standard mirrors do not support dimming.

So you changed the Werte to 39 on the interior mirror and that made your exterior mirrors dim more?

It's the factor between interior and exterior dimming. The dimming for both interior and exterior mirrors can be found under interor mirror settings because the sensor is placed inside the rear mirror.

Guys, having the rear sunshade up at night is what throws off the dimming of the side mirrors. Coding is only necessary if you want to keep the rear shade up at night.

I have not rear sunshade, so it's not "up" at night. I don't notice my side view mirrors dimming at all unless high-beams from an vehicle to my rear are DIRECTLY pointed to the rear view mirror. I'm going to give this a shot. Thanks for the info!

I can confirm this works. At 39, it's too dark with clear glass, but it functions as stated, above! This has been added to the coding cheat sheet.

This does not work on a 2014 LCI. Changed the wert to 39 and the side mirrors were no darker. Changed the rear view to dunkel and then the rear view mirror dims less, so I switched back to hell.

I have a 33% Tint all around (not windshield) plus 417 (Power Rear plus side shades). I have not had a chance to test out suggested or any other settings just yet to find the right balance of dimming.

But, I did notice something when playing around with SVT-CAFD tab of TM NCD / CAFD Tool. When I add 417 option, there are no affected functions. Yet, when I add 761 (Sun Protection Glazing), I get the following:

Code:
<<< CAFD_00000014.caf.004_100_010  (JBBFE) >>>
JBBFE > InteriorMirror 3080 > CODDT_01_SCAL_DIM_ECR_LIN = Dunkel 
JBBFE > InteriorMirror 3080 > ISP_HECKSCHEIBE = Dunkel
I thought it was interesting that CODDT_00_SCAL_DIM_ECR_LIN has only 1_0 option (Werte=20), while CODDT_01_SCAL_DIM_ECR_LIN has 1_0 or Dunkel (Werte=35)

Sorry for digging up the old thread.

Driving 2014 F10 now and also found that my exterior wing mirror did not dim as it should compare to my pre-loved e60.

May i know it is any update or solution to solve this ?

I was thinking just to change the value ( probably up to 35 not so dark ? ) on CODDT_00_SCAL_DIM_ECR_LIN (left mirror) and CODDT_01_SCAL_DIM_ECR_LIN (right mirror) and not sure should i touch the ISP_HECKSCHEIBE (HECKSCHEIBE = REAR WINDSCREEN) setting ?

Any input will be much appreciated : )

BWM rocks !
