hey mate, how did you check the relay and fuse? visually or via multimeter?

at times multimeter would provide you false indication that they are ok or in good condition. I often tell people to check the fuse visually as it may be holding on to it's last breath.

As for the relay, they can get sticky and sometimes show as working as it should, but once heated up, it changes its operation. I noticed you're in Finland, so I assume it's almost cool weather there every day?

both visually and multimeter and relay is bran new and relay also tested with directly applying voltage to make sure it clicks.
but no voltage applied to the relay when pump is driven via evoscans actuator menu.
and pretty cool this time of year yup.

Here :

Should work
Part No. MR409118
Replacement Part No. MN102703

So realistically they both will work.
