Rear lights not working on automatic

[elduderino]

Yes, I appreciate all of your help.
I was intending to get a replacement switch, but thought I would post here in case someone in the past had the same problem.

I went back to Google AI and asked “Can the light switch have both hardware & software faults”
What came back makes interesting reading.
As I have OBD11 Pro & never fully used it , I will give it a go , & follow the instructions.

I will post back with the results

Are you sure it’s not an aftermarket switch, I remember reading years ago that some aftermarkets switches don’t work well.
I’m not a big fan of the T6 switch or the lack of any daytime indication of light activation, so much pointless information available but safety critical stuff is lacking.

Just to be sure, what lights come on at night in the dark when the switch is set to Auto?

Yes , I checked. The rear lights came on automatically
The firm who installed the aftermarket, set the lights as Scandinavian DRL (installed 7 years ago Professionall) Rear lights would come on with front DRL in daylight.
Some how it’s reverted to VW Factory settings , that’s why I also have the dashboard error.
Will report back.
It’s 6.15 am coffee to finish, & a cycle ride

Back to normal time riding for me now it's not as hot. Did you know there is a T6 forum Strava group?

That sounds like a coding change then, rather than faulty hardware. What you have now sounds like standard VW setup.

Thread 'Rear tails on as DRL's'

23 Jun 2017

Hi all,

So I did all the basic coding last night (Alarm lock beep, needle sweep, digital speed thingy, seat belt warning etc etc). I then went and ordered some LED tail lights so wondered if anyone has set them to be on with the DRL's? I didn't see the option while looking through the coding section and I've not looked at the adaptation stuff too deeply yet but just wondered if anyone knows if it is actually possible?

Cheers all....

All sorted with the rear lights coming on with front DRL.
Just used the Scandinavian DRL one click app as I already had 203 credits, which I didn’t know I had.
Unfortunately the dashboard warning Light is going to take longer. I had to download the new version of the OBD11 app, & it wouldn’t accept my login details (which I know to be correct, cus can login to the website).
That is now in the hands of obd11 support.
Pleased about the lights now working, cus didn’t have to go and buy a new switch .

Do they need a 75yr old tail end Charlie
