5 Minute DIY CityLight w/Fog Mod (Props to "FatAuto" on AW)...

[FatAuto]

clealy your brother has a much better car

Ok homo, come over and bring some cash... Your car better.... NEVAR

[optionfans]

after reading the VAG problem, I guess B6 and B7 have different setting....which B6 has to do the VAG mod but not on B7, I will try this mod on coming weekend

FYI, I have Canadian B7

[tkilA4]

can someone that did the mod with a b6 get some pics up?

and is there a way to get the citylights going and the fogs going at the same time.

[Audi05s4]

so is there no way to do this with a B6 with out VAGing it

citylights... same thing as daytime running lights/corner lights? yes no?

sorry fat auto... but a pic of a b6 without ecodes with the mod please if possible...

I don't know about a B6, but for a B7 the city lights are different from the DRL which are different from the corner lights.

But you asked for city lights, no ecodes = no city lights. City lights are the small bulbs inside the highbeam reflector. An ecode has city lights and turn signals. A stock US housing will have marker lights (activated by the parking light switch) and turn signals. Daytime running lights are actual lights durring the day (fogs or low beams) not your marker lights.

I just did the fog light mod....is working on Canadian A4 too, no VAG is required.

ok then.. if so would this have my markers on and the fogs on at the same time or just the fogs?

markers and fogs.... can't put fogs on unless you twist the dial to at least parking lights

[tkilA4]

okay thanks sorry for being so complicated.

Many thanks to FatAuto and Eddie Man for this thread. Having just done this on my 2007 S4, I have a couple pics and a few notes that might help some folks get this done...

You can get access behind the dash by going thru the fuse panel. Just pry it open gently using a flat blade screw driver in the access slot shown by the red arrow. There are several spring clips around this panel, just work them out carefully and pop the panel off.


If you reach in behind the headlight switch you can release the connector from the DRL controls. This allows the entire harness to come out thru the opening.


Here is what I used to make the connection... Cut the #2 wire, slide the end that is still connected to the switch into one of these and crimp the whole thing down over wire #1... no wire stripping at all! This connector contains a gel that moisture proofs the connection, so it should be a pretty durable setup.

[zachf88]

is there a vag-com code to do this to the rs4 (b7)??

[va-terps4]

I believe the RS4 is still just a B7 (like mine) when it comes to the headlight codings and wiring. Thus, a VAG recode will set you up for "rest of the world" headlights... which includes using the front corner lights for signals only (no parking lights), and leaving the foglights on when the highbeams are active. But using the foglights in Parking/Citylights mode is only possible with the wiring mod described in this thread.

[zachf88]

ok cool! that was the answer i was looking for!!

[Jayme D]

Hey guys,

For both of these methods (btw - thanks a million for the help!) what do you do with the other end of the #2 wire (non-harness end)?

Thanks

Eddie Man,

I was wondering if you could post a picture of or the part number for those latest city lights I thought i remembered you getting. I remember we had talked bout me not really liking the LED quality of the city lights not dispersing light back on the reflecter and giving that soft glow but then I could have sworn you found some LED city lights that shing some LEDs back on the reflector and create a very nice soft light that is also matching in color to xenon. I could be crazy and have you confused with another forum member. Either way I appreciate you taking the time.

cheers! Mike

Mike,
I think you have me mixed up w/"MC Hammered" from AW...
He's basically carrying the torch on the latest/greatest info on LEs & the best LEDs to get for the B6 ecodes.
You can find him on the AW B6 forums (albeit; a search on that forum will prolly get what you want).
Sorry, I could not be of more help.

[bhvrdr]

No worries at all. I appreciate the heads up and taking the time.

cheers! Mike

He's actually quite active here on the B6 A4 Forums as well. But I'm sure Mike knows that already...

The mod works like a charm

I just did it today as well. Thanks for the DIY!

[roqsupastar]

is there anyway to wire it to the drl light feature? so that the fog can come on with the drl?

[todd1010]

So let me get this straight.

I usually keep mine on "Auto".

So when doing this mod and I keep it on "Auto" all I have to do is pull the knob outward to bring on the fog lights instead of having to turn the knob clockwise and then pull outward?

That is what sucks about this mod for those of us with the auto feature, at least the B6 - no way to put the fogs on in auto mode as as I know, I even tried with the Canadian settings.

[Rapture]

Has anyone had any problems with the city light bulb socket melting after doing this mod?

[va-terps4]

I think you have your mods confused.

The CityLight w/Fog Mod doesn't involve the bulbs at all. We've just rewired the harness behind the switch. I've been running it for several months... nearly all of the time... with no problems.

Some people have reported melted sockets when they changed from OEM to xenon matching bulbs. Others have reported issues with using LEDs. Whether you attempt either of these is completely separate from this mod.

[Rapture]

va-terps4,

Thanks, I have switched my city lights from OEM to Xenon match but they are the supposed to be the same wattage. I inquired here to see if there may be some way that this mod could have increased the power output to the city light. I know it is a long shot but worth a try.

I do have some socket melting and I am not quite sure what to do. The bulbs are stuck in the lamp housing.

I tried searching for this but had little luck. Does anyone know how to find any threads on this subject or any other resolution to this problem.

Sounds like I will be getting the clear corner mod out of this mess.

[arjzw]

so you insert the end that is still connected to the switch to the connector thing and wire 1 to the other hole of the connector thing? i did this and failed. my fogs wouldnt even come on normally anymore

[arjzw]

nvm!!!! i did it! GREATTTTT MOD.

[grauler02]

I did this on the b7 (still need to switch to rtw mode so the parking lights go off in city mode), except have any of you other b7's notcied when you lock your car, your fogs do not go on anymore?

[Dodge2Dub]

Mine still go on.

[zachf88]

how hard will it be and and how much would it cost to swap out the headlight switch wiring harness?

[PSYC0TIC ONE]

I couldn't see it being too expensive or difficult...

you would just need the actual connector from the dealer and some kind of pin extractor (i believe ECS has them but, they are on backorder right now)...

[PSYC0TIC ONE]

I think I'll do this mod to my car when I get my e-codes in... waiting on the seller to clear up the issues with the morons at UPS...

One quick question... I don't remember what thread (or forum) I read on how to actually remove the switch but... I think it was something like:

Turn the Headlight switch to just CCW from "Auto"
Push the moveable part of the switch in and turn CCW again
Then the whole thing should just lift out...

Is this correct?

You are correct, Sir. :)

[PSYC0TIC ONE]

You are correct, Sir. :)

i just tried it now and it worked... i have the little wire taps already (not like the ones the OP has, where'd you get them?)... I'd rather just wait to get the e-codes in and do everything lighting related at once...

anyone know where to get the LED regulators that were used in this DIY?

thanks again
