Check the real time data on the fuel/air (inspect for air leaks as well).
also any sensors that are out of spec.

and if you just reset or disconnected the battery - the computer takes a few hundred kilometres to get data back in the system for idle and revs.

I have to admit that I am a little jealous that you have a diesel Mazda5. I hope you get it sorted out soon.

I had OBD2 with Torque on my android phone. I saw many nice values, but no any fault. My DPF warning light was blinking, but there was no fault in diagnostic.

If your dpf is clogged - it will definitely cause power loss and could lead to engine damage. Not sure if any codes would be showing for this situation - we don't have the diesel in the USA.

Right , no fault code , must have a Mazda-Ford OBD ,for read a special PID's ...and also for Diesel too.

Must go on Mazda service connect to special box and start special procedure via OBD connector.
