Skoda Felicia consuming 250 mA when it is turned off

Hello, I have a Skoda Felicia 1.6 model 2000 and I realized the battery was being drained quit fast. I changed it for a new one because it was already very old and then, after seing it was still draining, I measured the current on the possitive cable that goes to the fuse box with every door closed and no light and I measured 250 mA, which seems to me quite a lot for this car. Note that I discarded the alternator and starter since I measured only the positive cable going into the fuse box.

Disconnecting all the fuses didn't do anything, I continue reading 250mA.

In the night, in full dark, I saw that the panel light for oil was slightly on (some current is being drained).

Also one extra thing I did is to disconnect the cable connectors in the fuse box, see picture attached. I discovered that disconnecting BE reduce the current consumption to around 90 - 95 mA (would this be normal for the Felicia?). The car started without the BE cable connector but the oil lamp is not showing at all in the panel, I think this is a bit risky in the long term and I would like to find a proper solution.

My guess is that the oil pump sensor switch is having an issue. I would appreciate any help in this topic.
