W210 passenger side rear fog

[Parrot of Doom]

Hi there

The passenger side rear fog light isn't illuminating, the dash doesn't give a warning, and the bulb is fine. Driver's side is ok. Both reverse lamps work ok.

Any ideas?

Fog lamps do not show up in the lamp fault window.
Have you tested the lamp or just looked at it, looking at it is not fool froof.

Ah right thanks, in that case I'll get the multimeter out and check the plug to the light tomorrow.

I swapped the bulbs side to side, the fault stayed on the one side.

Is there a common point at which the wiring for these 4 lamps meets do you think, thats easily accessible? If I can't trace the wiring I may just snip it, and take the power from the working lamp.

Is there supposed to be a n/s rear fog light? My 201 estate only has an o/s rear fog light.

This being the case you could link the two, these things are often wired for LHD and RHD, the harness normally come down one side and on to the other lamp, If the lamp holder is live it may not be grounded

Only one fog light

There's only one fog light but two reversing lights. EEC regs as I recall

Correct. Only the OS should light up. There isn't even a holder for a bulb in my 210.

 

[Parrot of Doom]

Ah right, how odd. Theres a holder and a bulb, and the bulb sits in a fancy little holder!

Maybe they keep the bulb in there as a spare.

Sod them anyway, I think I'll wire it up. Plenty of other cars around with 2 fogs.

Yep, definitely only 1 foglamp on the back, out of the factory. Not for long though

Had same problem......seems i have two lamps but the nearside is definitely not wired!! That was the official response from the MB dealer. Nothing in the manual about it and MB delaers usually tell you something is normal to avoid fixing it. but this time they are right, only meant to be one foglamp!

W210 Estate

Hi,

I was doing a pre MOT test check myself and noticed that on my W210 Estate the N/S/R fog lamp works and not the O/S/R which is strange as this is the one that should work in the UK.
So I changed the bulb and still nothing.I'm going to connect them together so that both work.
Just a quick question.What is the correct method of removing the rear light cluster?
I undid the two 8mm nuts and twisted it out but it's a bugger to re fit as it's very difficult to slot the clip in then tighten the bolts.
Do I need to remove the tailgate trim?

I felt sure that I answered this, you only require one offside in the UK, its up to you if you want two.

Thanks Malcolm,

Sorry I've posted twice.

If it's only one does it matter which side?I thought that it should be on the O/S/R.
Also any ideas about how to re fit the light cluster that I've already removed?At the moment it's held on by the two 8mm nuts and it's loose at the other side.Do I need to remove the trim?

It failed the MOT today because of this Fog lamp.
I found out that originally it was used by someone at NATO in Germany and therefore only the NS fog light works.
Would it be ok to connect the positive lead from the non working Fog lamp to the positive on the reverse light near it?.

As Malcolm says you only need the O/S in the UK I,ve wired my N/S up by looping off fom the other.
W210s did,nt they have issues with back light lamp holders over heating and melting if this is the case i would be wary about wiring up the other side and creating more heat.

 

[Bluegrass]

The problem is that my car is set up for use in Europe so only the N/S lamp works.The UK spec is for the O/S.
I have replaced the non working bulb and cleaned up the connection, but no joy.

If I wanted to do a loop to the working fog lamp would I need to remove the tailgate trim?

If you can see the colour of the wire on the near side that goes to the fog lamp, it will be the same colour as on the other side, thats ok if you have access to the wiring, if you do not then the trim must be removed.

Have you checked to see if there is a fuse for the Offisde lamp.

If you give me the first 9 VIN numbers I can check but cant promise to find anything.

You will see how it comes apart here.

I went to the link but there's no image when I click on my car model.

The regs that give us only one fog lamp are supposed to help us distinguish stop lamps from fog lamps. I have heard supposedly clued up people suggest that it it penny pinching on the makers part but it aint its the rules.
i.e.
A/ only one bright red lamp in front = slow down (brake) cos the bloke in front does not want you to run in his rear end.
B/ two bright red lamps in front = slow down (brake) cos the bloke in front does not want you to run in his rear end.
simple init?

I have only used my rear fogs during very heavy motorway spray which reduces my forward vision dramaticaly in daylight. If I cant see the chap in front can the chap behind see me?

Also please note that fog lights are only intended to be used in real fog that truly impedes your vision, if you can see the tail lamps of vehicles in front for a reasonable distance do you need to have your rear dazzle lamps on?
Real fog will reduce your road speed to a crawl and using correctly set front fogs without head lamps will improve your abillity to find the gutter and centre line. Front fogs are for use in dense fog and hard driving snow only.
To use the lights erroneously will mean that you may cause dazzle which contravines the road vehicle lighting regs (section 27 I think) and may get you a pull from those nice british policemen.
Getting too close means being able to read the registration number of the car in front and in firing range of my screen washers.
