Hello!

New to this forum although I've been using VCDS on and off for more than 4 years. Carried out minor tweaks on my previous cars (2003 VW Passat 3BG TDI, 2007 VW Touran 1.9TDI).
Mostly been altering light settings, auto locking and other minor tweaks.

Now I got this Skoda Octavia 4x4 2.0TDI Combi MY14.

Have done some minor alterings:
- Both rear fog lights at the same time
- Enabling boot closing from the interior button and the keyfob
- Enabled lap timer i Maxidot
- Enabled needle staging
- Enabled rear lights (and instrument lights) together with DRLs
- Enabled fan speed to be displayed in AUTO mode
- Enabled DRLs (LED stripe) to dim when flashing the indicators
- Deactivated the AM band on the Columbus MMI
- Enabled automatic daylight saving time in the Columbus MMI

But, there's always a but. I have not yet been able to alter the setting/threshold/sensitivity for the light sensor controlling my lights in Auto mode on the lights switch.
Living the most western part of Norway we don't get much daylight these day, but still I would expect the sensor to light only DRLs (LED stripe) and NOT the low beam in the middle of the day. Even if it is overcast.
I do know about the early, middle and late setting in the MMI but it does not make much difference.

I have been searching and reading both this forum and others but still have not found any solution to be able to alter the sensitivity of the light sensor to keep my DRLs lit during bright daylight even these days getting close to winter solstice.

I have read that in some models you should be able to alter byte 2 in the RLFS? drop down menu in 09 Central Electric. But mine refuses to accept anything other than the default setting by selecting the proper car model in byte 1.

Any suggestions will be welcome.

Please find a complete auto scan of my car below.

Arguzen: Hi. I thought that I would respond for no other reason than because I think that there is a weird "symmetry" between our relative positions on this fragile planet - both close to the Arctic and Antarctic repectively (happy to swap mountains of snow for long periods of sweltering heat)

Anyhow - enough of the frivolity! As to your question, I don't have your car, but I do have your particular RLFS (details of which I repeat from your auto-scan below)

Code:
   Rain Light Recognition Sensor: 
   Subsystem 2 - Part No SW: 5Q0 955 547     HW: 5Q0 955 547   Labels: 5Q0-955-547.CLB
   Component: RLFS  024 0042 
   Serial number: Y13M10D11H01M33S24S4
   Coding: 02805D

The bytes that define the car type on my RLFS is:

which aligns with your setting for Byte 1-2, but the sensitivity values are in byte 0, not byte 2 as per your post

Try adjusting Byte 0, I guess. If the long coding helper won't permit changes, try altering the values directly in the "Open Controller screen"

Hello DV52,

I have never been "down under" but it's on my bucket list.

I'm partly agree with you regarding the sensitivity being in byte 0 rather than byte 2.

In Byte 0 you may make the threshold to act earlier, not later as I want to. At least this is how I interpret the different settings in byte 0.

On some models (Golf 6 among others iirc) I've seen that you in may enter some sort of compensation factor related to the tint of the windscreen as to make the sensor less sensitive.

In my car the byte 2 is fixed and related to the model selected in byte 1.

I just might accept the fact that in my neck of the woods we just don't get enough daylight during the winter to get full use of the Auto function of the light switch.
An other downside is that the navi screen goes into night mode along with the low beams been lit.
I just have to get used to flip the light switch to "0" to turn on the DRLs and get to navi screen into day mode.

Arguzen: OK - Not sure if this will apply to your car, but I note that you have a high-end BCM (which is encouraging). Have you made an adaptation channel control module for the BCM?. If so, does the admap include the following two channels ?

(1)-RLS_Night_Sensitivity-p_lx_rs_day > 500 lx
(2)-RLS_Night_Sensitivity-p_lx_rs_dawn > 200 lx

I don't have these channels on my car (I have a medium-level BCM) but I interpret the 'day' channel to be the threshold ambient illumination to switch-on the lights at dusk (i.e. being 500 lux) and the 'dawn' number to be the switch-off illumination level. Again this is a guess, but I hypothesize that the code changes that can be made in Byte 0 of the RLFS use the number in the 'day' adaptation channel as a reference (I think).

So if you have the two channels above - then you might try experimenting with different numbers. I suspect that a SA will be needed and I hope that the magic number 31347 will apply (again, another guess).

Don

PS: As for your bucket list -as the old Italians used to say "carp diem" because "tempus fugit"

DV52: I do have those two channels, but they appear with errors stating that they are not available.

There's an other channel as well. I don't remember the title from the top of my head, but it's related to some sort of delay for when to switch between "day" and "night". I will have to dig further into this when time and opportunity make it possible.

PS: I ticked of a major point on my bucket list this summer: Route 66 from Chicago to Los Angeles on motorcycle. It still puts a big smile on my face thinking back.

A short update.

Have had a day with real sun shine and no clouds in the sky. The light sensor seems to do its job. The DRLs got lit and everything looks as expected. I put my hand over the sensor and the low beam got lit. Removed my hand and after a few seconds the low beam went out and the DRLs got lit again.
It seems that the sensors and electronics in my car and myself disagree on how much light is required to light of the DRLs in stead of the low beams.

Still digging for that hidden piece of info on how to tweak the sensitivity.

Hello Arguzen,

I had in the beginning problems with the coming home and leaving home activation.
The setting down where after retrofit the rainsensor wrong.

So i have change the valeu to this and now 95% works great and somtimes i olso have problem when i drive out of a garage the lights stay 15 min on on a clear bright day.

IDE04926-ENG116608-Comfort illumination-Helligkeitsschwelle Forward-Messung,116
IDE04926-ENG116605-Comfort illumination-Helligkeitsschwelle Infrarot-Messung,2

You have like me the software version H14 112 AA
You can update the BCM to AE version H14 124 AE ore 134 AJ.

I have made the update to AJ but then i had a problem with the door led lights the ilumunate when the door are open and not close.
So i downgade back but this rainsensor works better with the AJ version.

Yes when you update to AJ version you can change this valeu, and more where you see now a fehler not with version 112 AA

(1)-RLS_Night_Sensitivity-p_lx_rs_day > 500 lx
(2)-RLS_Night_Sensitivity-p_lx_rs_dawn > 200 lx
