I have thought about trading it in but I want to investigate my options first. I could not sell it privately and sleep at night.  No smoke!  Apparently modern synthetic oils and the CAT are stopping exhaust smoke.

5,6,7,8 and 9 are on the agenda.  The car is booked into my local trusted mechanic in a couple of weeks.
PCV will be the first thing checked.  I considered taking of the rocker cover and  checking the PCV myself but I do not have the equipment to do the other tests so, I will leave it all to them.  I will post again if anything comes to light.

Do you have a multimeter or at least a lamp-based probe?

Thank you. Any ideas where I should start to find the problem spot and try to fix it?

Hello and welcome.
I agree it looks like a loose connection. Bear in mind that it may not always be the 12V supply. It can also be a poor connection to the body as the return path for the circuit.
