1998 v70r battery drain sometimes

[Janpy]

Goodmorning
Im Jan, living in the netherlands and owning a V70R , before a 850R.
And i have a strange thing going on in my car
Now and then my battery drains.
I did some research, and it seems relay 2/32 stays on.
When i pull fuse 11b/1 it shuts off
Replace the fuse it stays of.
This relais is switched by the ecu pin 41 -12v.
When i remove the ecu there no -12 on the relay
So no leeking 12v.
Also the ignition 12v to the ecu is switching normal.
Has ony one had experience with this.
Or am i on the wrong path and is relay 2/32
Always on for a while after switching of the igintion key?

Thanks
Jan
