if the ECU thinks the DPF is blocked then it won't allow full engine power so I'd suggest;
taking the car for a long drive where you can keep the engine rpm up over 2000 rpm for around 30 mins this will get plenty of heat into the system and get the system into re-gen mode
if that doesn't help then consider
or even removing it completely as you'll still pass MOT's fine without it, the key thing is to have the ECU re-programmed so its no longer looking for it
On cars where the DPF is removed then typically you get more power and more mpg as it restricts the exhaust even when new
Hi tried running the car only goes into limp mode the temp sensor would also make the dpf think it is full l need to sort the issue with the temp sensor not do away with the dpf
