Odd question about my my14 octavia I have coded it to use the fog lights with the full beam but they only work when flashing the lights not when you push the stalk forward to keep the full beam on so any help there would be much appreciated and we did have the cornering lights activated and this was working fine but has stopped working since coding the fog lights with the full beam?

Sounds like the change you have made to the leuchte file only includes the "headlamp flash" value, it needs to include the "headlamp main beam on" value too.
