I always follow your footsteps to diagnose these mazda 😊thsse are nasty in diagnosis always gives codes to simply through you off track 😮...great diag and explanation sir.cheers bro

Had a very similar scenario with a nissan... It had dpf solution elsewhere and had a bad job of it and they said to him it will be fine... I diagnosed it to be a glow plug to be failed stopping the dpf to regen... There's people buying software cheap and these have a go heros are deleting stuff because they can't fix the original fault and causing other faults by doing so.... The customer now states his mate can't do it cheaper after all!!!!! It gives you a massive headache and chase your tail for no reasons

I see you have a garage full of Mazdas too 😂😂

Hi there Peter I’ve just watched this video and it’s bothered me I believe you’re correct in the diagnosis btw but it’s got me thinking though lol next time if ever you see that car again or indeed another Mazda 1.5 diesel if you look on the intake manifold the charge air cooler is tucked inside and on that charge air cooler is a map and temp sensor combined it’s not perhaps that at fault and I’m also led to believe there’s an intake temp sensor from the turbo outlet or inlet down the back of the engine on a plastic pipe hmmmm lol

Car looks perfect cosmetically but a right mess really..! Fair play Peter and great to have the CX-3 to cross compare…that helped to guide your conclusion for certainty. Having deleted the DPF and remapped I wonder from that point forward was the P0111 error present or did it develop at some later point and if so what triggered it..once remapped that version shouldn’t change? I know removing the fault from the system table means it will never show but is it now true to say that overall the car won’t run at it’s optimum as it thinks it’s moving close to the sun at 215 degrees and so would the computer think at 215 degrees air is less dense and adjust fuel etc. accordingly…this car could be back to you again for much more serious intensive care work ☺️‼️

Fair play Peter that was a head wreaker.

The yanks seem to be able to look up all info on any car quickly, is this not available in Europe?

Drilling dpfs..Holy god!

Sir IAT. Sensor was bad. ????

i would of swapt meter off other car then car u would see straight away
