VW Golf failed on rear fog lights..

JonathanAnon

I had my NCT last week... Failed on the following.



I went about trying to fix the fog lights tonight and when I turn them on this is what I see...



What am I missing?

thanks.

Intermittant fault.

They look suspiciously like tail lights, Mk 4 golf has only one foglight on the rear. At bottom of the cluster if I remember.

Nissan doctor

The fog lights are supposed to be beside the reverse lights on a MK4 are they not?

Pique

Seriously, did you turn on the lights without the rear fog on and compare how it looks to when you do have the rear fog on?

If not, go do that.

Yeah, sorry, you're right.. it's exactly the same when I just switch on the normal light..

I tried googling to find out what they should look like, but couldnt find anything. I'm also aware that the Golf Mk5 has foglights ONLY on one side... But I cant find a picture of what they should look like..

Just replace the bulb?

Nissan doctor

As far as I remember the fog lights should be as marked below:

I was just working on the "illustration", Nissan Doctor...



Should it be both D segments that light up when I switch on the fog lights?

I think there was only one side that worked on irish/uk cars. I know on the bora it was only a matter of putting a bulb in the other side to have two rear fog lights but I think you had to run a wire across on the golf!

Nissan Doctor (and the others) are correct. The rear fog is below the normal rear lights and beside the reverse light. It was on the drivers side of my old Mk IV Golf, so it does indeed look like yours aint working.

Yeah I googled through images and a few forums, but I couldnt find one as conclusive as that one.. thanks Sean.

This is the one he describes as Brake light and fog light..


I'll check the bulbs in it today.

sean1141

no problem. it was on the first padge of google search.

i dont know what way he has that wired in the pic above but the fog light should only be on when the rear parking light is on. you need at least the parking lights if not the dipped lights on for the fog to work

Okay one bulb was gone in the right, but the contacts seem to be oxidised on the left.. Any quick way of cleaning these besides sandpaper?

Wd-40 and a cotton bud would certainly help..

The one on the right will be enough to get you through.

I was thinking about that today, because I read when I was googling that the MK5 only has ONE foglight... Asked a few friends and none of them could tell me for sure...

oh and you might have noticed the missing headlight screw on the test printout (in my OP).. went in to Halfords today, asked the guy did they have a screw for a Golf headlight.. he says... "why dont you just use the screw from the other headlight".. I asked him why was he working there and not NASA..

JonathanAnon

Hi lads, I was trying to get the second foglight working today and I think I now know the reason why... pin 6 (which IS the fog light) on the left side tail light is not even wired !!!!

My Golf is a 1.4P 2002 MK4, is this the same on all of them??

TrailerBob

As i said in post 2 the Mk4 golf had only ever 1 foglight (drivers side) for the Irish market, I had a 02 one a few years ago - something to do do with that being the minimum requirement here - my Toyota is the same. Difference is in the golf, the wiring doesn't exist for it. Put in the new bulb on the drivers side and you'll be grand.

Btw you're wasting your time in halfords looking for a screw for that headlight. Go to a decent hardware shop and ask. (most likely a 3mm x 25 self tapper will do the job) as these 'parts' are not sold in a motor factors

I do a bit of metalwork, and I didnt even know what to ask for .. It does look like a self tapper, so I will ask for one of these.. thanks Bob, appreciate the help.

sean1141

you can run a wire from the working foglight to the other side to have two working fog lights. on the bora the wiring was in place but they only put a bulb in one side.

get the headlight screw from a dealer. they will only be a euro or that. also you could get one from a breakers yard. they are threaded iirc

Wheelnut

Some countries prohibit two rear foglights so that there is no confusion with the brakelights.
