The phantom fuse.

Fuse that serves DRLs on the BiZenon  setup please.

I'm pretty sure there is a fuse for the lighting on the left and another fuse for the lighting on the right.

 

If only the DRL aren't working, it's unlikely to be a fuse

Nothing showing in the manual for DRLs, but 15 showing as light switch.

Why are you looking for it?

[Bexhillian]

There is an option DRL Disable/Enable within MAXIDOT Settings (Manual page 65) if this is what you are after, but as logiclee queries, what is behind your initial enquiry?

[Creakingjoints]

Thanks for replies on this. I'm getting an intermittent failure on the nearside DRL with all other lights OK. Just wondered if it was on a separate circuit with it's own fuse. Looks as if its the DRL unit itself so I've ordered up a replacement of Ebay. Skoda OEM about £85 but aftermarket same unit for BMWs  for £30 so not a bank breaker.

Sounds more like a bad joint.

Exactly what I am dreading. If it's inside the light unit it's going to be fun. That's why I was looking for any other contact points in the feed.

The only wiring inside the light unit is the wiring to the plugs for the bulbs. 
Have you considered that the bulb itself might be faulty?

[Creakingjoints]

The "bulb" is an LED embedded in it's own circuitry and cooling system attached to the outside of the headlight unit. The wiring could be problematic as there is barely enough to attach the LED unless you have the fingers of a five year old. Hmmm ! Where's the nearest five year old.

You have highlighted one of the problems here: you haven't mentioned the age of your car, so you are getting advice for both type of DRLs.

[Creakingjoints]

I can tell what year of car/cars you drive Graham without your posting.

I have however got a proper circuit diagram now, and no, no dedicated  fuse. As Bexhillian remarked, the DRLs can be deactivated using the MFD though. The how and why escape me but I can live with that.
