Where are the Headlamp Fuses? - mstraka - 28-01-2015 02:35pm
I am having a problem with the driver's side (left) halogen headlamp operating in my USA 2013 Evoque – both high and low beam are out. The owner's manual lists the fuses but there is no headlamp fuse shown. There is an AFS headlamp fuse mentioned in the engine compartment fuse box, but I don't have the AFS, auto leveling - lights turn into corner feature and it appears this is for the turning operation of the headlamps and is not for the actual lighting of the lamps. Are there fuse / fuses for the headlamps?

no fuse mentioned in my handbook either. but surely there is one, maybe a misprint. have you checked the bulb ?

From what I can tell, the Lights are driven from FET's in the Central Junction Box (P101) containing the Central Electronics Module (CEM).
No Fuse that I can see.

I didn’t know that both high and low beams used the same filament so that when the bulb burns out both high and low beams go out. I thought it was a fuse issue since both intensities were affected. The bulb was a high output halogen Sylvania Sulverstar Ultra. Great improvement over the stock bulbs in light output but this one had a very short life. About 15 hrs.! No I didn't touch the glass when it was first installed. Sylvania notes that because of its high output bulb the life is 1/4 the normal 65 watt and estimates its life to approximately 120 hrs. But 15 hrs.? I still find it odd that there is no fuse listed for the Evoque’s headlights in the owner’s manual.

maybee the bulb acts as the fuse ?

The FET will have over-current/temperature protection built in, resetting when cooled or switched off, and will act faster than a fuse.
Glad it was simply a Bulb to solve your problem, although surprised it's a single filament, there are 2 circuits dipped beam and high beam. you sure that 1 blowing didn't just take out the other, or destroyed the common connection.
I use +90% bulbs from GE on my Volvo (Halfords are doing 2 for 1 at the moment) these seem to last quite a long time.

The pair of bulbs, where the one burnt out, both have deposits along the inner side of the glass bulb. Each glass has two pools of this dark deposited stuff about 180 degrees opposite each deposit and also a third deposit at the tip of the bulb glass. Could this have been molten solder and contributed to the failure? Definitely only one filament in the bulb.

there is only one filament, the dipping is via electro/mechanical dipping of the bulbholder.[/font]
