UK-POLOS.NET - THE VW Polo Forum

I own a 2013 Polo 1.6 TDI 90HP CAYB, the car came with H4 headlights and the previous owner sold me the car with H4 headlights but in a terrible condition so he also gave me H7 headlights he bought but he didn't have time to install them.
When i turn on the high beam the low beam shuts off but when i flash the both beams stay on. I checked VCDS in the 09 module (cent electronics) at byte 22 and in the top of the screen bar where you can write the code by keyboard it is already "00"
Is there any way i can make the both beams stay on? Do i have to modify the wiring? Is there any risk of modifying the wiring of the headlights?

From H4 to H7. viewtopic.php?p=508917#p508917

If you follow what is posted here, the only risk involved is one you create yourself, either through an incorrect installation or by using unsuitable tools, materials or wire. In other words, it is very easy to do and will last forever, but it still depends on your own personal skills.
