My Yeti is the facelift model with I believe LED daylight running lights built into the headlight, these are not serviceable to my knowledge.

 

I noticed today that neither are now working, I cant say when they stopped but it would have been quite recently, I have not coded them out using VCDS and the DRL option is ticked under the lighting menu of the maxidot, I tried unticking it and reselecting it, restarting the engine again but they still dont work.

 

Any ideas?

 

I will try to activate them using the output tests on VCDS but had not yet  downloaded the software to this new a few months ago computer, I installed the files today but it is telling me that I dont have the latest version 😯, perhaps the older program was copied from my old machine. Anyway getting that working will be a job in itself albeit one I must do, I have to plug the unit into the computer then connect to the car which is then out of range of the wi-fi signal......................

 

For this time it would be quicker for me to do an old school multimeter test, does anybody know the wire colours to probe in the headlamp connectors? @Breezy_Pete?

Just about to watch something on telly; tomorrow?

I dont think you need to now.

 

I was mistaken, they are not LED, I thought they were because the DRL is a strip at the bottom of the headlight which is in fact a seperate lens, it contains a single bulb which doubles for sidelight and DRL being at a lower intensity in sidelight mode.

 

The sidelights work correctly so it must be either a programming problem or something amiss with the body control module, I have in the past tried and failed to get the coming home/leaving home function working but that was a long time ago and the DRLs worked until quite recently.

 

If I do the non Maxidot setting procedure (pull indicator stalk back and hold up for 3 seconds after turning ignition off) I can hear a small relay click each time.

The coming home/ leaving home function requires you to have automatic lights (sensor built into the rear view mirror) to function AFAIK. Does your Yeti have that, John? It's normally paired with auto wipers. 

Thanks for that Lee, no it doesn't, its a poverty spec model, that makes absolute sense now that they would not want it functioning in daylight, it was dumb of me to spend so much effort trying to achieve the impossible.

 

I would not rule out that I coded out the DRL function and forgot about it immediately.

It was something I wanted on my Rapid until Carista told me I needed auto headlights to enable it that's why it sprang to mind.

So to round off this topic with the conclusion.

 

I was having a very senior moment, I had not programmed out the DRLs which was some relief that I had not forgotten doing so, they were in fact still working, the other night as I switched off the lights and ignition I thought I saw some illumination from them but try as I might I could not repeat it, tried restarting, reversing driving forwards, switching off again, - nothing

 

I should add that of course I cannot see them while I am driving and I only notice them when parking at night after turning the headights off, tonight I saw they were definitely working but once again when I tried again there was nothing, I even got out to check.

 

Eventually I found out something I had been aware of in the past the bloomin things turn off when you apply the handbrake! 🙄 so unless you park with the handbrake off and get out to check you will not see them.

 

In the past I had noticed it when parking in front of a reflective shop window so was aware of it.

 

What now has me scratching my head is the other night on a straight main road with no other traffic I turned the switch down to sidelights and could see a tiny glimmer but when I switched it right off there was nothing and the DRLs should have been a lot brighter, I concluded that they did not work at night and the subsequent testing at home made me decide they were not working at all, that still remains a mystery and I will test again, my vehicle does not know if it is day or night, it does not have the light sensor.
