What symptoms are you seeing from the fault code?

Am I right in thinking you retrofitted auto lights recently? If so it might be worth mentioning what was changed/coded as part of the retrofit.

Yes retrofitted auto lights with a new rlhs and a used auto light switch. When the switch was in the auto position before I ran the extra cable from the switch to the BCM the lights would be on all the time but no fault code. Now I have run the cable I am getting this fault code come up.

Just the Amber warning symbol on the dash a lighting system fault message on the maxidot and a warning on the infotainment unit with the headlights coloured orange but the lights seem to be working OK

I'd expect you'd need to update the coding on the BCM/Cent Elec module to tell it that it now has the auto lights switch and RLH sensor. Have a read of this thread for the Golf:

I have followed one very similar and I think I have coded it correctly need to go out and double check it someone said it was a faulty switch on one of the skoda groups on Facebook

Just been out and double checked the wiring and the coding and followed this guide and hey presto they are working with no fault code thank you all for the help and advice you are fantastic. Now just got to work out how the ch/LH function works as I have the options to change the time settings on my infotainment unit now

 

Here is the guide I used to get it working "

 

I have no errors showing and both rain/light sensors are working as well as coming/leaving home functions.

I have a 2013 FR and the parts numbers I used are 5Q0955547B for the sensor and 5G0941431AF-WZU for the switch which has the correct colour lighting, only difference being the small amount of silver trim is brushed aluminium rather than the chrome on my original switch.

To start with swap the sensor and switch as described in the other instructions, fire up OBD11 and go into control unit 09 Central electrics.

Select Long Coding

https://farm5.staticflickr.com/4400/36663263431_23ae6c6021.jpg (https://flic.kr/p/XRNNTz)

Select this symbol to move from the textual long coding into the standed format.

https://farm5.staticflickr.com/4340/36663263141_6d16335439.jpg (https://flic.kr/p/XRNNNz)

The screen will now look like this, notice the byte 00 in the top left hand corner. Press the arrow in bottom right to move to byte 06.

When there select the tick box indicated (bit 01) and hold the green tick to save the settings.

Arrow once to the right (byte 07) and make sure the screen looks the same as mine with bit 0,1,3,4,5,6,7, all selected, hold the green tick to save the settings.

Now go back to the control units menu and select "Adaptation"

https://farm5.staticflickr.com/4374/36663262401_1b7a124cdd.jpg (https://flic.kr/p/XRNNzP)

Select Assistance light functions.

https://farm5.staticflickr.com/4404/36663262131_4628aa8a4e.jpg (https://flic.kr/p/XRNNva)

Make your adaptations the same as mine. I noticed at this point that I had less available adaptations than in Deathjam's guide but I just made the ones I did have the same so don't panic if you have more adaptations just fill them in as in his guide further up the thread, hold the green tick to save the settings.

https://farm5.staticflickr.com/4348/36663262081_18f3ef6755.jpg (https://flic.kr/p/XRNNui)

Back to Adaptations menu and select "Comfort illumination".

https://farm5.staticflickr.com/4436/35967814334_ea3f6e9a69.jpg (https://flic.kr/p/WNms6U)

And again make sure you adaptations match mine, hold the green tick to save the settings.
The last thing that threw me a bit was the 2 settings below, you will notice they have different values to mine. It wasn't possible for me to enter those values in OBD11 so after a bit of searching the internet I found that the values I have used (2 and 116) were the correct ones.

(6)-Comfort illumination-Helligkeitsschwelle Infrarot-Messung 18 lx
(10)-Comfort illumination-Helligkeitsschwelle Forward-Messung 46400 lx

Disconnect from the car and turn the ignition off, you may have to go into car setup to enable the coming/leaving home "
