Audi a3 2.0 tdi BKD Ignition Issue: Error 18009 & Terminal 30 Start Failures

Hello, as in the title, error 18009, the car does not start, when the ignition is turned on, the incandescent light turns on and the power steering starts to work even though the engine is not working, after about five seconds the fans are turned on, the fuel pump in the tank cannot be heard. After turning the ignition off and on several times, it is surprising, the chek engine light appears, the pump can be heard and the car starts. Then it goes out and it's the same again. I will add that the fuses and relays are checked, the masses are checked. There used to be a problem with the unit injection, but it does not crash this error anymore, I do not want to suggest anything, but it's piezo siemens and if one is damaged, the car will not start

You replaced the J317 relay - because it points to it.

Relay 458? Yes, I changed the main ignition

Added after 1 [minutes]:

Relay 458? I changed this, the main ignition and 433 I changed places

The contacts of the relays are functional - how do you bring your nose closer and smell it?

I wrote, all fuses and relays were checked, the cassette next to the battery was also removed, the contacts were OK

In place of J317, after turning the ignition, there is power on the coil of this relay? - The connected 21 W light bulb is normal?

There is power on the current contact to ground?
On the second contact, the current draws the current - the connected H4 bulb from the + battery to the contact should shine half of its brightness.
