Hello,

Story is simple, dpf and egr were having issues and i removed them.

About 1 month later it pop up P2458 error and i disable it in file.

This was 3 months ago and car was fine, now the car as dpf sign in dash and permanent safe mode. (coincidence....apparently a sensor was disconnect and giving some kind of pedal error, car went away and this dpf issue returned after all this time.)

Car as no present dtcs in diag and the pedal one is gone since the plug was connected.

Tried to disconnect egr and dpf sensors but remains the same, (in diag dpf was at zero before trying to make dpf and pressure sensor reset).

Perhaps a update on the ecu and make it all again?

Any ideas are welcome as i am kinda stuck and car is coming tomorow.

Original and egrdpf file in attachment.

Thanks.

Br.

Michael

It was made by OBD.

I've seen water in original ecus but doesn't seem to be the problem.

Regarding the issue that the car had, was giving some permanent dtc's fom water and something else, i just update the ecu with a newer frf version, made new file and sent him to a local shop to fix those issues.

Well
I think your DPF solution is not correct
If it’s correct it’s not regenerating it’s self and shows codes P2458
