Rough start

Charge well the battery and next time run the 5 pedal purge trick before you attempt to start it and if it starts well after that then first replace the air bleed valve in the filter head and if no improvement it's time for injector copper washers IMO, would be good to replace the main relay(R9) with a new one as well. Check coolant temp and fuel temp before the cold start, they should be the same in the morning

Battery was fully charged, also bleeding with pedal purge trick, nothing helped. Copper washers are new (1 year), also tried a different set of injectors. Fuel temp is always 1°C above coolant temp when I start. I will try a new main relay, because this one is not new.
