T6.1 Auto light switch upgrade.

Hi @chetwyne,
I’ve just changed my switch for 5G0941431BD, which has the auto setting and front fog setting. I expected I’d need an additional plug in light sensor for the auto headlights, but bizarrely it works with nothing additional. However when on auto mode it throws up a bulb failure warning even though everything is working. When you switch to manual headlights the warning goes out. I’m not sure what the issue is and haven’t had chance to play around yet. If anyone on here has any knowledge I’d love to hear. Thanks

I have the Auto switch in my SE 2012 Passat and the non auto switch in my 17 plate Transporter Shuttle SE.
I noticed that the dash lights brighten up in bright sunshine and then dims under cover, shade, cloudy etc. So I assumed that there must be a sensor in the dash somewhere. In my Passat it's in the rear mirror mounting,
I just changed the Auto switch from the Passat for the T6 and as it's now dark, the auto light switch works. The wife is not pleased as the Passat is in her name ....
I did look at the difference in the pins on the rear as the non auto switch has one less pin, but the lights came on when in auto.
I'll have to test in the daylight but it looks ok so far.

That's interesting. I'm going to try a proper auto light switch in the Polo. Whilst the cheepo kit I fitted works OK, it doesn't turn them on with the auto wipers if the ambient level light is too high.
I fitted one to my startline t6.1, same error message and the rear fogs don't work, thinking of "modifying the wiring to allow front fogs to be fitted. Anyone got the wiring diagrams for t6 and t6.1 headlamp switch? Surely it can be done?
What's the error message?
In the following downloads:

Thanks for the info, I haven't had chance to read the error messages yet but will post when I can. They clear when I switch to side lights or sip beam.
Sorry to resurrect an old thread but did this ever get solved for a t6.1 startline? Do you need to fit front fogs for the auto headlights to work without error?
No mate, I fitted front fogs using the travelinlite kit with a separate switch. Too much work unfortunately.
