Question please

[Sootchucker]

Hi Guys. Wondering if those with a 7.5 could check this out for me please (don't know if it changed form a MK 7). Just driven into work in pea soup thick fog. I therefore put my front and rear fog lights on. Now on the light switch, the green front fogs light illuminated, but for the rear one, I got nothing. The symbol on the switch for rear fogs never changed.

At first I thought my rear fogs weren't working but I got the warning light up on the dash and when I arrived at work sure enough it was on. I thought the symbol on the light switch itself was supposed to light up, as the front ones do but in Amber not green (pretty sure it did on my older 2016 GTD) ?

Also I thought it might have something to do with that the lights were in the Auto position, so I flicked the switch round 2 clicks to headlights (which changed nothing) but also I noticed that the headlight position never lit up as well ?

Is my switch faulty or is this how everyone's work ?

Every VW that I've had for the last 20 years has given the green light on the switch for front fogs and the one in the instrument binnacle for the rear ones.

The switch needs to be to the side light or dipped beam position to turn the fog lights on. This is so that when you turn it back to Auto or Off, the fog lights turn off, therefore aren't left on for the next time you drive.

BTW, I trust that you turned off your rear fog light as soon as it was obvious that the following car could see your tail lights? Although we all know when to turn them on, few people treat them like main beam, and turn them off so as not to dazzle other drivers.

Exactly the same as the switch/indicator in the Mk7 - everything's working as it should

Yes, its working as per my Mk7.5.

Watch out for auto lights though in fog - the sensor sees the fog as white, so the headlights don't come on.

If its foggy, first thing is to turn the headlights to on and then use the fogs as appropriate - which isn't on if you have traffic in front or behind you!!

That's not always possible tho'. You could be at the back of a line of traffic where front fog lights aren't necessary, but you need the rear one on until another vehicle comes up behind you. Oddly you can't have rears on without the fronts.

On the very rare occasion that I do use rear fog lights, I make a point of leaving them on for a few seconds when a car approaches from behind before turning them off. My thinking is that it will more noticable to the driver behind that I have turned them off, therefore hopefully passing on a little education about how to use fogs lights courteously.

Thanks guys, good to know it's not broken (although still seems a weird way of working)

Don't worry about me having them on when I'm in traffic as that's a real pet hate of mine - people with fogs on when they are not really needed.

I had them on as there's a stretch of unilluminated country road that I travel on for about 3 miles, and like I say it was pea soup this morning, so they were only on when travelling down this stretch (with only a few occasional cars). When I came to a more built up area they went straight off, as I find the front LED headlights and rear LED tails are usually more than bright enough.

I once got nagged by a cop car in front of me about my front fogs. It was foggy too - not just me being a chav boy racer.

To be honest, I can't remember the last time I used my fogs - front or rear.

The only thing the fronts get used for is coming on with high beam (coded with OBDEleven) for better lighting down unmarked country roads lol.

Most people don't know how to use fog lamps anyway, they are only supposed to be used if visibility is seriously bad.

The rule is, if you are having difficulty seeing other cars, they will be having problems seeing you, so use your fogs. At all other times, leave them off.

That's useful to know Fred - cheers
