Hi everyone,
Does anyone have experience with the xexon headlamps. My high beam does not work on one side. It flicked a lot one night l and now does nothing on the drivers side. (passenger side is fine)
It seemed to me like the leads for the high/low solenoid must have been shorting or something. I can get in the back of the unit easily. But can't see any major fault. Does anyone know someone who is experienced in fixing these kinds of things. It's beyond my medoicre tiny electrical wire experience. That and I don't want to put the head lamp in the oven to get the cover off, so suggestions welcome there also.

I've been meaning to strip mine down, the passenger high beam on mine sometime flicks off, only on bumpy road and only when the light is pointing fully left.


I can only guess it's a bad connector or almost broken wire if it only does it point left.
Problem is that it happens so infrequently that I forget to check it when I do have time.
Would be good to see inside one beforehand.

Mine did exactly that on the night it failed. Would work with the directional lamps going left. I'm sure it has nothing to do with the humpback bridge earlier that day.

Unfortunately the MOT is due soon. Do we think it'll pass. The best I can see is that main beam has to work in pairs.

If it comes on when the car is stationary then it'll pass. The direction only works when moving, part of what's putting me off looking at mine, not sure how to make it point left short of jacking up the front end.

 

[JamesWheeler]

No mine doesn't work at all

It's a rubbish screen shot. But that's in the back of the unit. But it's that metal solenoid and the pink and yellow wires that do it. (my wires are broken by my own ham-fistedness) but there is then two tiny leads that come from the other side of the connector to the actual solenoid coil

Looks like you'll need to dismantle the whole light

 

[JamesWheeler]

Yeah just not looking forward to doing that. As best as I can tell I need to heat up the sealant before unclipping the front. Me and plastic clips don't get along. And a replacement unit is pretty expensive

 

[JamesWheeler]

Well it passed the mot. So maybe they don't look too closely at main beam

 

[vexorg]

Must have worked when they tested it

 

[JamesWheeler]

Nah. There's no way it could have. The wires aren't connected inside any more. Good news either way

 

[vexorg]

Never had an MOT where they missed something like that

 

[JamesWheeler]

They were picky about stuff like number plate lights so I can only presume its not technically a failure. The regulations that I could find were very specific about dipped beam stuff and barely anything about main

Hello everyone, I'm Lukas from Poland, sorry for my bad English.


I've been struggling for couple of weeks with similar problem. Left headlight doesn't work on high beam, it's flickering. I thought that the reason was the bulb itself, so I switched them, I took the one from right side and put them into the "flickering" headlight but it didn't change anything, the bulb from left side was working fine (both on low and high beam) on the right side, when the bulb from right headlight flickered on the left. Then I switched the ballast from one side to another, same result.
And then I found out, that the problem could (and probably is) be with the directional headlights mechanism. When I drive straight or turn right the left headlight doesn't work on high beam (low beam is OK). When I start to turn left it turns on and work fine. So there must be something wrong with this directional system. But what could be the case? Broken wire? Bad connection somewhere? Shorting? As you know getting inside the unit requires dismantling it completely. Is there any other way of fixing it?


Thanks for any advice.

Probably better with a new topic, what type of headlight?

It's a 2012 DS4 with bi-xenon headlight.
