2013~2016 Fault code P253F

[Petros26]

Hello everyone! I own a Mazda cx5 2.2L Diesel 2014. I bought it in 2018 with approximately 70000km and now it is at 190000km. So far I had to rebuild both turbos, replace the engine head, reprogram and permanently disable dpf. All these done a few years back, but now we have a new issue, a red warning light, with low engine pressure warning. Is this likely to be a programming issue as I saw online?

Thanks in advance
