Hello

its likely that your garage is using a generic scan tool to read the code and these can sometimes get confused so I'd agree a main dealer or mazda specialist should be able to help more

however as its flashing the DPF then

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

or

On cars where the DPF is removed then typically you get more power and more mpg as it restricts the exhaust even when new
