If the DPF is clogged to an extent that the diesel is bursting the high pressure pump seals and leaking into the sump, I'd stop using the car and get it drained / fixed or it will grenade.
The two may not be related i should have added, raising oil levels in diesel's is 90% of the time a failing HP pump - no warning lamps will show directly relating to it, aside from oil level obviously.
