Indicators flashing fast after LCI upgrade

Hi everbody
I really need help...After I installed the Xenon LCI headlights, I coded everything, the xenon bulb and the flashing work, even the 3 diodes in the corner are connected, but I have a problem with the turn signals. They work twice as fast, flashing. I set the option to have the front LED turn signals, turned off the cold/warm check, however, they still work quickly and flash after that, does anyone know how to solve this?
Please help...thx

I can't understand and find what has changed and what the problem is. I only marked that the car now has Xenon lights, turned on the flash to pass it would be xenon instead of halogen, marked that the front turn signal led, turned off cold/warm check, but still the problem.I have FRM3 modul

Did you change the VO and code it to the FRM and CAS?

No, I did not add VO or touch the CAS module. I only coded Xenon Lights, Flash to pass with Bi Xenon in the FRM module, turned off the cold/warm check, and turned on the front Led turn signal

You will have to do that and i think you have to modify your build date also. What FRM do you have? FRM3 or FRM2?

if I add that VO, is there a possibility that I will lose all the settings now and will everything work as it does now?
and do you maybe know why the fog corner lights won't work because I turned it on, but it doesn't work?
In any case, thank you very much for your help
