I own a 2010 Yeti and I’ve got a problem with my full beam headlights. It’s the bi-xenon version and the dipped beams work fine. However, when I switch on the high beams, only the left one comes on while the right one remains off. There’s a distinct “click” sound coming from the left one but nothing from the right one. Any thoughts on what the problem might be? Perhaps the shutter? Also, is there a good solution for this that doesn’t require switching out the entire headlight? 

Sounds like the HID "bulb" has failed. They can be changed in the same way as a normal bulb, however it is probably worth changing the both of them.

Tried changing both “bulbs”, unfortunately didn’t work.

It will not be the Xenon ‘bulb’ as it is working on dip beam, so it does point to the shutter.

Is the shutter difficult/impossible to replace? Am I looking at switching out the entire headlight?

It’s not something I have looked at TBH.

The shutter forms part of the "bulb", so that is all that has to be replaced, not the whole headlight unit.

Look on EBay for H4 HID replacements as an example

The shutter is part of the projector, not the bulb.

Tell me where the shutter is on a D1S Xenon bulb, why look for H4 HID replacements when he has Bi Xenon?

 

From memory the Bi-xenon units have only one bulb that does high/low beam and its just the shutter (which is part of the projector unit not the bulb) that moves out the way to give high beam. If so the shutters are also operated by the travel mode in the maxi-dot menu, Try it to see if the beam pattern changes on both lamps, If one doesn't change then it looks like the shutter servo motor is at fault. The shutters are also operated by the suspension when the ignition is first started up for the self leveling height adjustment. no mater what they should both work together.

Well my understanding was that on a bi-xenon unit the shutter is part of the "bulb" unit, and not part of the headlight. That is why I mentioned the H4 replacements.

The shutters aren't activated by the self levelling. The whole projector is levelled (and turned) by self levelling and cornering functions.

Your understanding is wrong.

And H4 replacements? Where did that come from? They won't even fit in the headlight.

Ok that makes sense, cornering function obviously a different thing, 

Am I right about the travel mode? When selected the shutters shade the top of the beam and the cornering function turns the projectors to the side to prevent dazzle. the cornering function doesn't operate when in travel mode.

The projectors move up and down for self levelling, and move left and right for cornering. The shutters work for dip > main beam > dip. Travel mode I'm unsure but I presume it changes the shutter angle to blank a certain part of the light pattern for continental driving, and I'm also unsure about cornering functions but it sounds reasonable that it also turns the projector to present a different beam pattern. Never used travel mode as not been abroad for some years.

For a Yeti, the shutter can only be either open (main beam) or shut (dipped beam), there is no in between or partial setting.

 

Travel mode for a RHD aims the projectors down and to the right slightly to avoid glare, it doesn't alter the cutoff at all. For a LHD vehicle it would be down and to the left slightly.

 

Some VW models have roller shutters which are able to alter the cutoff between a few preset shapes, I don't believe this has been used on any Skoda model yet.

 

@Llanigraham - H4 are not used in any factory fit xenon systems as H4 bulbs should only ever be halogen based. Any H4 xenon/HID bulbs are solely designed for retrofitting and unlikely to be road legal in the UK or ECE areas.

 

Back to the OP's question, as mentioned it probably the xenon shutter that's at fault. This could either be wiring, the solenoid or even a mechanical issue preventing the shutter moving.

 

You'll need to take the headlight off to inspect it, it's not designed to be user serviceable so a dealer will suggest you buy a complete new headlight. If you're lucky, it might be possible to remove the projector, fix it and refit without needing to cut open the headlights.

Ok, great! Thank you! I’m feeling preatty sure I’ll have to replace the whole thing, but hopefully I can at least get away with finding a used one in good condition that I can use..

 

Any good guides out there on how to remove it?

I think the Skoda/VW part no you'll be looking for is:  5L2941017C and do not be surprised if you also need to replace the xenon headlight ballast control unit at the same time as well - part no: 5L0941641A

Yeah, I suspected as much.. So basically the whole thing plus a little extra. 

 

Dealer estimate for this = 12-14000 Swedish crowns, roughly 1000-1200 GBP. 

 

Edit: Thanks for the numbers! Maybe I’ll feel brave and atempt the switch myself

Ouch!! Though I presume that's including full fitting which will be quite time-consuming.

Awesome, thanks!

Albeit in May 2015, I paid £248.70 incl UK delivery for a new headlight unit.

Fingers crossed I can find a deal like that!

 

Paying well over a thousand for a damn HATCH that won’t open properly would really suck big time..
