Unfortunately this is just the way it is, mine does exactly the same.
There is so called dpf additive cleaners but none of them solve the problem, you can split the dpf to remove the filter block or get a bypass pipe made up but you'll need it remapped and the regens removed from the ecu, which is the expensive part. I too wish it was, as simple as just yanking the middle section out. Though some people are over-charging for this work.
Mines booked in at gorse performance In thetford to be done and is costing me £350 vat inclusive to have the dpf bypassed, the egr delete, performance remap and regens removed from the ecu. Plus they'll give you an mot smoke test just for piece of mind. They were recommended by a friend.
