No longer work low beam headlights

[Andrea 6r]

Hello everyone,
I have headlights xenon bi aftermarket,I have a diode and I had a coding
last night, suddenly, you are off the headlights and I can not get them back to work
I tried:
to raise the diode
to raise the encoding
to check the fuses
to disconnect the battery
changing column switch lights
a scan with the vag that does not mark errors
high beam work [only lever pressure "sfanalando" manually (not leaving the lever pressed)], I also tried to put a light bulb on the edge of the low beams, but it does not work!
There perhaps have some, a relay, which does not "know"?
thanks

I had a similar issues with HID's installed which blew out my body control unit and Wiper motor because of a bad ballast.

If i was you i would check the control unit and see if that helps. I'm not sure what if the control unit will directly affect your headlights but if you have had HID's installed, it could cause this issue.

so if you pull the column switch lever towards you, for the high beam signal, it works? if so, you can rule out the headlight. that's working fine.
also, you lost both of the headlight at the same time?

not sure I understand right
you're telling me to check ballast of headlight?
this?

exact, pulling the lever work (it seems with less intensity)
they are "turned off" simultaneously

I should have understood the cause of the problem: a contact between the diode and the mass
I have now reinstated the original connection, but still do not work on the low beams
The vag still does not give errors; I checked all the fuses are all OK
there are no other problems to the electrical system
where I can bang your head?
ps I also put the pin 3 of the light switch (that is, that of the "fixed" lights but still not accessed the low beam)

I solved : it was the relay 449
I changed and low beam lights work again

Hi. Andrea 6r. I think l have the same problem. How did you get access to the relay. Did you remove the lower plastic fascia on the dashboard ? If so where are the fixings and which parts no l need to remove to gain access to the relay. Thanks Steve
