Too much oil is bad because extra oil gets burnt and blocks the DPF.
Suck or drain oil out to get to normal level.
Forced Regens can only be made on an engine which is Running properly, is error free (no fault codes), at normal temp, and DPF soot Levels are not too high.
If you have any faults you have to fix them first.
If the DPF filter is too blocked you have to remove and clean it or replace it.
