Volvo EW160B (2001) – Electrical / Electronic issue when cold

[Milos 123]

Hello everyone,
I have an issue with a Volvo EW160B, year 2001.
When the machine is cold, I turn the key and:
the display keeps blinking
I can hear clicking sounds (relays)
this lasts for about 5 minutes
after that, the machine starts normally
Once it has started, it runs and starts normally for the rest of the day.
The colder the weather, the worse the problem.
Has anyone experienced a similar issue or has any idea where to start troubleshooting?
Thank you in advance.

Another guy on here had relays clicking and replaced the relay that was causing it. So switching relays around to find the offender might be possible.
