Front left headlight main beam not working.

[Dimitar Timev]

Hello all.
There is a strange problem on my A2. The Front left headlight main beam is not working evry time. Allready replace 2 new bulbs h7 but the problem is still remaining.
The right headlight is working fine.
So my suggestion is some bad wiring ,or bad relay ?
Can someone tell me are there 2 relays for the main beam lights.Or one for the left headlight and one for the right? Or there is only 1 relay that controls them?
Also where is the location of the relay, and can some one give me the part number for the relay or relays.

one relay. One fuse per side, I'd check that first.

Fuses are ok.
Can you tell me number for the releay and location?

The relay controls both bulbs, so is unlikely to be the cause. I'd start looking at the actual connectors at/inside the headlight.

Yes 10 min ago i manage to find realy burned wire inside the headlight for h7 bulb.
I manage to repair the wire with the soldering iron and some new wire and connectors.
For the moment the headlight is working again.
But can some one point the location for the relay. Just to chek it.

You're after the X contact relief relay. Item 9

However, I think you've now solved the issue, but the cause is still left to decide - was the burnt wire caused by bad contact (rattling/arcing), moisture or something else?

Moisture is a problem yes.
