Running Lights not Working

Strange. Your side markers (orange) are working. According to the wiring diagrams, these are spliced into the wiring for the main lamp assemblies. This means your relays and fuses are ok.

I'm not familiar with the internals of the main light assemblies, but maybe you do have a dual lamp (or internal power supply failure) failure. Ouch.

If you can find a yellow/black wire (on the left side) or yellow wire (on the right side), going to a plug on the back of the light assembly, check these for 12 volts.

 

Maybe someone knows which plug is which...

... and how to access the rear of the light assembly.

 

Externally, there doesn't seem to be any logic which stops the LED strip working when your headlights are on. If there is any logic, it will be in the lamp assembly itself. Anyway, your lights don't seem to be working whatever the configuration. The Park lights and stalk switch controlled lights have separate fuses and relays, but ultimately, the wiring is spliced together before entering the lamp assembly.

 

According to the manual which can be downloaded here

'Position' lights go on at the first stalk click

The fairy lights come on when you do that, or when you hot the P button on the center console

They stay on when low beams go on, not sure about high beams

If I were to take a guess, I would guess somehow you have no bulbs, not sure how they would have both failed or it would be electrical

Maybe someone worked on them and didn't put them back. These are small, fragile bulbs, could be a fluke and they are out.

The fairy lights are the small 'valeo' rubber cover in the outside corner of each side which you just pull off

You should be able to access through the fender well hatch without removing the lamp from the car or even the fender well cover, though it would be easier if you do remove the fender well cover.

I'd start with that

I had the same problem and it was the bulbs. Can be done with the tire on but it's not easy.

 

I replaced mine with the SCUDing and when I pulled them out they were looking pretty nasty

Hopefully that's all it is

 

Are you saying they are individual, replaceable lamps and not LEDs soldered onto a flexible circuit board?

 

Unless I am misremembering they are just small bulbs that illuminate the plastic tunnel

Which is why they are not that bright

I will have a picture in a couple of hours

I am talking about the OEM ones not the scuding

I meant when I pulled out the OEM ones that were looking pretty nasty

the Scuding ones are absolutely spectacular LED frames

I used these LED ones , brighter than the hella bulb... looks a bit white also, matches the HID's better

FWIW, Normal Guy Supercar has a DIY Youtube video how to replace the LED strip lights.

 

nah, if you are then I'm in the club, think we've all had our DOH! moments.

you must be enjoying the new look!

 

Trust me I checked every fuse in the car before I decided to check the bulbs.
