Hazard lights
I have a problem with the rear hazard lights in C5.
When I turn on hazard lights, the rear lights don't work, the front hazard lights only work. Turn signals lights work normally, front and rear.
Have any of you had such a problem?

You will need to install a hyper-flash harness.

A hyperflash harness will NOT fix this problem. It only helps with normal signals flashing too fast.
It's the hazard switch. It has a bunch of contacts that switch the lights from the normal function to the hazard flashing and something has gone wrong inside it.

The turn signals do not flash too fast.

The rear lights do not work, but only in the hazard warning mode. When turn on hazard lights the front lights signals flash.
When I turn on the turn signals, they work both front and rear. Problem is only hazard lights and only rear lights.
Yes, I have the lights converted to the euro version. The stop is separated from the turn signals. I did it by disconnecting the famous and well-known white wire under the steering wheel. Then only the brake light in the middle lights up and the rest of the brake lamps are powered from it.

I'm coming back to this topic because I have a problem with the lights. I have modified the lights on the Euro version, I cut the safety white wire. The problem is that I also lost the rear hazard warning lights. The rest of the lights work perfectly fine. Maybe I cut the wrong white wire. Can you tell me which one to cut?
Thanks in advance and greetings from Europe.

When one function stops working after a modification or change has been made, I like to undo the modifications until everything is working normally again. I would start backtracking your changes (perhaps starting with reconnecting the white wire) until your hazards, turn signals, and brake/tail lights are working normally. That way you will know what change made the hazards stop working.

I did just as you wrote, I returned to its original state.Only now I have again direction indicators associated with the STOP light, as it is in the original. I want the STOP signal separate from the direction indicators. I took the STOP signal from the middle STOP lamp.
