HI. My headlight range adjusters won't work. So I found electical scheme using Auto DATA

 

 

I measured the voltage on the range adjusters connector (1 - ground, 2 - ajusted voltage, 3 - +12V Battery trough fuse F20 15A).

I got these results:

between 3-1 I got 12V,

between 2-1 I got range from 5v to 11,7 V, depends of position of headlight adjuster switch

So its like is suppose to be.

 

I think that bought my headlight range adjusters  are dead so I opened it and tried to figure out the electrical scheme

 

 

 

 

I'm trying to figure out witch is the 8 pin IC, so I can replace it. Everything else seems to be working.

Note: The 1,7kΩ potentiometer is the one inside adjuster switch.

Any help will be great. Thanks

What model and year octavia do you have, also does it have xenon headlamps installed?.

It's 1999 Octavia 66kw. No I don't have xenons.
