Technical Parasitic draw investigations

[Beeinaflowerpot]

Hi folks, new here having perused lots of old posts recently as I work my way through a ton of electrical niggles on my new-to-me van.

Full disclosure, I have no idea what I am doing but I am a doer and am giving this my best shot.

Fiat Ducato, 2013 plate which was converted to a campervan by previous owners.

I have identified two parasitic draws which were draining my battery within days.

First one found to be the Blue and Me, which I have now removed (will need to do a proxi alignment but that is in motion).

The second one is baffling me. Draw currently showing as 0.38 and a clicking sound can be heard under/behind the steering column when testing. Removing fuse F53 reduces the draw to 0.18 and the clicking sound stops. This appears to relate to the instrument panel. I suspect a relay somewhere but I can’t for the life of me work out where to look for it?

Could I please have some pointers on this one? Video attached for the noise.

Personally I would start with items previous owners fitted in the camper conversion, such as split circuit charging systems, any after market alarms etc.
I had an Iveco van that after locking it up the generator light would come on and over a week or so drain the battery, I eventually traced it to a non original wire on the brake light switch to do with an aftermarket alarm and tracking system.
In the old days it was usually something simple like a glove pocket light etc. but now there are many things to check , so a process of elimination.

Thank you for your suggestion. That might be a huge can of worms that falls far from my capability.
