When Hendrik van Meurs, bishop of Osnabruck died in 1450, Rudolf involved himself in a succession struggle, the Münster Diocesan Feud, that lasted for years.

Rudolf attempted to put his nephew Conrad of Diepholz, provost at Osnabrück, on the ecclesiastical seat.

Rudolf van Diepholt advanced the construction of the Dom Church, and he was interred in a chapel that carries his name.
