B7 Auto Headlight Switch in B6 Non Auto...No Fogs now

[Boosted3.0]

I got sick of my B6 switch being torn up so I found a B7 A4 headlight switch. The B6 one I'm trying to get rid of it a three position switch (Off, Running Lights, and Headlights). Now I pulled that out and put the B7 one in, however now I have no fog lights (front or rear) when I pull the switch out. Auto headlights work, side markers work, as do my regular headlights.

Is this something I can VAG out or is the switch not compatable?

so when you have your headlight switch on Auto, do the headlights come on automatically when it gets darker? and when you put the switch all the way to the right as to turn your headlights on manually and you pull the switch out you get no reaction to the front and rear fogs?

[Boosted3.0]

It's like dusk right now, but when I switch to Auto it takes like a second then the headlights pop on, however in auto position you can't pull out for fogs. I'm pretty sure Auto just means they come on when you start your car and go off when you take the keys out because there is no light on buzzer when I turned the car off in auto position.

And yes no reaction from front or rear fogs.

Also the plugs in the back are identical. And I switched back to th B6 plug and my fogs still work so I know I didn't blow anything.

[FourGermanRings]

what year is your A4? so no reaction from fogs even when you turn your switch all the way to the right like you use to with the old switch? i did not know the auto feature would work on the b6 w/o any modification.

[manguyen]

You will lose your fogs, unless u rewire I believe. Don't use my fogs so it don't matter. I run one of these switches .

[Boosted3.0]

02 A4

Manguyen what do you mean rewire? How or what do I have to change?

[manguyen]

You would need to know what pins did what on the one switch and compare it to the new switch. I think the pins are switched around on the new switch.

[Boosted3.0]

Anyone know? Or can I just hardwire my fogs to something so they go on as soon as my car does?

[AudiA4Turbo22]

google it and u'll find out.

[Boosted3.0]

No luck on google. Have a link?

[Boosted3.0]

Or a diagram of how I could wire the B7 switch to work. It's really sweet lol.

[jon102034050]

ive got a b7 switch w/o auto and mine functions the same as yours..... i would like my fogs to work as well.

[Boosted3.0]

I just need a diagram and I'll piggyback it to the driving lights or something. Unless I can VAG it?

[plug1]

Why didn't you just get a replacement B6 switch? Or why don't you do that now and save yourself some time?

[Boosted3.0]

Because I don't want to. Love the look of the B7 switch.

[QTC]

On the B7, the fogs don't come on in the auto position, but they do come on when the switch is turned all the way to the right (the manual lights location). Don't know if that helps or not...

[Boosted3.0]

Yeah no fogs in any position. Idealy I would like to have fogs in auto position.

[A4natomical]

How does the auto feature work when you don't have the ambient light sensor?

[Boosted3.0]

Leave it in Auto and when I turn my car on lights come one, when I turn my car off, lights go off. Oldguy where are you????

[Boosted3.0]

On the male end of the plug my wires are colored from position 1-17 as follows.

1. Black
2. Black and Yellow
3. Purple
4-7. No wires
8. Green and White
9. Gray and White
10. Brown
11. Yellow
12-13. No wires
14. Gray
15. Red
16. No wires
17. Blue and Gray


What is the male end of a B7 plug look like?

[dirtybrd]

Why is the B7 switch so much more attractive?

What makes the positrac rearend on a plymouth work? Some questions just don't have answers.

I really need a pic of the male plug or a list of what wires go where on a B7 plug

[dirtybrd]

No, I'm asking if it looks different other then the auto label. Easy there Joe Dirt!

Haha to be honest I'm really not sure. Compared to my B6 switch the lights are much crisper and the green lights really pop (which matches my navi). Also I didn't have the auto on and off feature...and now I do sort of. Just trying to work out the wiring and make a DIY.

Hey Boosted 3.0, did you ever figure out the wiring to get your fogs back?

I plugged in the same headlight switch (sort of auto-headlights) but I too don't have fogs anymore.

[NyteEscape]

im assuming that since there is no sensor, the lights just comes on with the car, no matter if it's light out or not?

[sa_seahawker]

Must be my "noob"ness but I can't tell the difference between the B7 and the B6 switch

[manguyen]

^^ you can't tell the difference by just looking at it.

[misterjj2u]

Exactly. I guess it would be the same as simply leaving the headlights on all the time as well.

For me, my original switch was peeling like a mo-fo but I picked up a new B7 switch from the classifieds.

[manguyen]

^^^ i love the auto feature on a non oem equipped xenon car. I have an auto switch and my fogs work. i cant remember if i got it off a b6 or a b7, but i really think it was a b7... im an 02 btw

[plug1]

This seems like such a waste of time. Get a B6 switch and be done with it. I don't get why anyone wants to reinvent the wheel by using a B7 switch in their B6 when they look exactly the same.

[manguyen]

theres a slight difference the the color of the light that some of the logos emit on the switch as mentioned by boosted3.0

[Sales@RAI]

Does the auo function work now? I always wanted that

[plug1]

I got that...but is it really worth all this trouble and discussion you guys are going through? Without seeing them side by side, even I can't tell the difference between the two.

Oh well, not my car. Just my opinion that it doesn't seem worth it at all.

I got it b/c it was listed in the classifieds and wanted to replace my crappy / peely B6 one.

Sorta. It's like leaviing the lights on all the time but you don't get an annoying beep telling you your lights are on when you turn off the car.

Ok i had the same problem and everyone said it couldn't be done which is technically true but there is a work around. I replaced mine because it was peeling as well so really the only thing your concerned about is the front plate section. I don't have pictures but i will try to explain what needs to be done to get your fogs to work because yes it will not work with the current setup your trying to run. Basically this is what you need to do:

Sit down in a comfy chair and prepare to get frustrasted because it's kind of trial and error process.

First you need to remove the front plate from your new B7 headlight switch. This is the piece that is in good condition and not peeling the reason for buying the new switch.

Next you need to remove the front plate from the old B6 headlight switch. The piece that is peeling and looks like shit.

Swap the new b7 pretty none peeling front plate onto the old b6 headlight switch backing.

The auto function will now turn on your daylights if you move the switch down one more position it will turn on the headlights if you pull out the switch in that position it will turn on the fogs and then can be pulled out further for the rear just like with your old switch (well technically your still using your old switch just a different front plate).

Everything lights up and looks perfect that only thing that is slightly misleading is the "Auto" function which really only turns on the day running lights you don't have the real auto function.

Now obviously the steps where you remove the front plate from the new switch and place it on the old b6 backing is a little more complicated then what i described above but i had no DIY and sat down and looked at the thing for about half an hour and figured it out. You need to put a little muscle into it and don't be afraid to break the piece it's pretty strong.

[Boosted3.0]

Wow suprised this thread came back lol! I never figured it out, I have the B7 switch in but I miss running all HIDs at once.

teg2audi...I figured that out a lonnnnnggggg time ago. I would rather not have a fake position on my switch. Also my B6 switch got soo bad even the center piece you could start to see some light coming through lol. I'm sure there is a way to wire it however nobody seems to be chiming in with anything constructive.

[jrdemail]

I hate to resurrect an ancient thread but it's better than creating a new one. I solved the original posters problem with a B6 auto switch replica from Ebay. Operates perfectly and I still have use of the fogs. Also it was under $35 shipped and looks perfectly original.
