I know this one is been done to death I have a fl vrs with auto dim mirror and wipers I want auto lights is it a case of swapping the switch round and having the vcds plugged in and coded or do I need to anything else.

First thing is to remove the switch and check that all the wires are there. Is you have an empty connector you will also need to install an extra wire down to the comfort controller.

I did mine and took me about 30 mins.

The connector has no empty bit it's full

Should just be new switch, fiddle with VCDS and you're away.

Or if you are lucky... just a new switch

 

that said i think the early elegances should have had auto lights but there was some sort of screwup with the wrong looms.

It would log an error if auto lights were enabled but the switch wasn't installed.

Yep if all the pin slots are full you just need the switch and then tell the car it has light assist with VCDS.

It's a nice simple little addition I think.

I also changed the sensitivity setting so the threshold of the lights coming is a little sooner.

Phil

Wasn't auto lights part of the package that gave you the dimming mirror though?

Don't think so. My car had auto wipers and dimming mirror but not auto lights. But the 4x4 has a slightly odd spec compared to the elegance.

Surely the light sensor is in the same unit as the rain sensor though?

I certainly had it as part of a package and know that I wouldn't have paid 'just' for the lighting side. Then again, I did also spec xenons so there is an outside (but unlikely) chance it could have come with them?

Nope dimming mirror is completely separate. There is a front facing sensor on the passenger side of the mirror. Friends have a caravelle with the dimming mirror but no rain sensor.

Mine didn't.. but as soon as i cabled it to the ccem it worked fine.. 

That was what I was hoping you'd say change the switch and the codes and it works so now I can order the switch knowing I haven't got to do any wiring.

Interesting, removing the switch with the battery connected logs a fault. Did you original light switch only have 7 out of 8 pins in the connector?

I would have thought if the wire wasn't connected to anything but AL were activated then it would log a fault, it wouldn't bring error light on though.

Yes the light sensor is in the same sensor as the rain. But as above mine just came with rain wipers and auto dim mirror but no auto lights. I think the light assist was a £75 option on the elegance with rain wipers.

 

Funny that on a Superb MKII I did some coding on it had auto lights but not auto wipers. He was told the auto wipers were an option so he didn't bother. It was just a case of turning auto wipers on in VCDS. So it was the other way round on this one.

Also if you put the switch in and code it without the wire in place the lights just come on all the time. I know because I tried it. I think it must be a fail safe if the switch fails.

 

Phil

Yeah i only had 7 out of 8 pins populated and ran a repair wire down to the CCEM and auto lights just started working, no faults were logged until i unplugged the entire switch assembly. 

 

the extra pin is just the setting for the auto lights selection on the switch so probably won't log a fault as it probably just thinks that option is not selected. 

I took my switch out and looked at the connector and it's full of wires there is no empty gaps coz I have read somewhere that you might have to run a wire from number 2 block a pink or purple one to some module and I wasn't going to do that but the wire is there.

Also for reference here is a link to a thread with some further details including where to connect the wire for those whose need it.

Found it in my favourites from when I did mine:

Thanks phil for the link.

I've fitted the switch and had it coded but it still not working when in auto the lights are on during the day here's a couple of photos of the light connect to the switch and of the control unit where does the wire go to so I can make hundred percent sure that it's there in the control unit when it was coded it was dark so couldn't test

Are all the wires present in the connector? - i.e. no empty spaces.

Sent from my Nexus 4 using Tapatalk

Yes the connector is full all 10 spaces are full of wires.

I would get the coding double checked. Is it a OEM switch or a cheaper alternative?

Sent from my Nexus 4 using Tapatalk

The switch is OEM got from skodaparts.com it lights up and the front and rear fog lights work.
