Still got my on going problems with my Xenons, the last month or so they have started flicker ocassionaly then eventually will flick off. If i turn them off and on they come back on. I’ve changed ballast, ignitors and bulbs. What else could it be? 

Cheers

Wiring I’d say. You changed your igniters for new?

Fuses, headlight switch, all-sorts of fun.

Moisture can cause havoc with the positive feed, just like ignition cables.

I’ve tried several different ones now.

I’ve checked fuses and all look okay. I’ve tried a headlight switch as well. Is there some sort of relay for the lights?

I’ll have to follow the positive feed back and check that👍🏼

Still not got to the bottom of this, double checked all the fuses, tried another switch and another headlight/ballast. I’ve tried to follow the wiring back into the scuttle but i can’t see much out of place or corroded.

Driving me up the wall now😒

It’s gotta be wiring or the module then mate surely, need to really explore the loom, you’d  be surprised how some stuff can look fine but be totally knackered.

If the supply voltage is low, then they can exhibit the same symptoms. Is the car charging ok? Check the volts when you first turn them on, then again when they start flickering.

I’ll have to get a multi meter and try it. Car charges and starts perfectly as far as i can tell!

Yeah definitely get the lines tested, if you were closer I’d check it over for you, have you had it scanned lately?

Got myself a multimeter today, the power going to both headlights are exactly the same. This is the odd things, I swapped the headlights over today and the problem follows the headlight. So i swapped the bulb, same problem. Swapped the ballasts, same problem. Swapped the back casing with the wiring, same problem. What else can it be?😂

Nope just the one headlight, but i’ve swapped everything over and even tried another headlight. So confused

Oh, could’ve mentioned that! 😂 When you said headlights I assumed it was your headlights. Ok, so start again, one light is flickering, you swapped them over and the flickering one is still flickering? Or the other one is flickering when plugged into the other ones plug?

Ah my bad! Yeah it still flickers when i swap them over and they are a slightly different colour. But swap the bulbs over and the problem stays with the flickering headlight.

And you said you have a spare headlamp, what happened when that’s fitted?

Is it a full spare headlamp or do you have to put the other bits in it for it to work?

Both bulbs flicker in the spare headlamp using both plugs or just in one side?

Ok, just so I’ve got this right.

Original lights fitted both sides, only one flickers

When you switch the lights the one that flickers i.e the offside one, that one still flickers when it’s fitted to the nearside.

Switching the bulbs makes no difference to the original headlights.

When you put the spare headlight in on either side with either bulb it flashes no matter what. 

Does that round it up correctly?

Does the ht breakover in the socket? What condition is the bulb socket like?

I’d say you’ve probably been unlucky with your spare headlamp and it’s duff, hence it’s faulty wherever it goes, and the other original one is dicky too. You do put your car through it’s paces so it’s not unlikely that you’ve jangled summat loose. I’d be on the look out for another set of lights. 

Or a better/cheaper idea would be to find a friendly local-ish gti owner who doesn’t mind lending you theirs for a night or two, you know then that the lamps are sound and can take them out of the equation if the fault persists.
