Good morning, everyone,

a strange thing happened to me in a workshop:

FIAT 500 1.3 MJET 75 HP, CONTROL UNIT IAW6JF.

OIL WARNING LIGHT FLASHING, SO QUALITY RESET NECESSARY.

WITH NO DIAGNOSIS TESTER WAS POSSIBLE INCLUDING THE OFFICIAL MANUFACTURER'S TESTER.

I COULD NOT UNDERSTAND WHY, THEN LOOKING CAREFULLY AT THE PARAMETERS I REALISED THAT EVERYTHING CONCERNING DPF (TEMPERATURE PROBES, DIFFERENTIAL PRESSURE SENSOR) DID NOT SHOW ANY VALUE BUT LINES (---).

IN THE END IT WAS FOUND THAT THE DPF HAD BEEN ABOLISHED IN THE ENGINE CONTROL UNIT AND WHOEVER DID IT CERTAINLY DID SOMETHING WRONG AS IT SEEMS TO HAVE BECOME FASHIONABLE RECENTLY TO ABOLISH THEM BUT UNTIL NOW IT WAS ALWAYS POSSIBLE TO RESET THEM.

I HOPE THIS IS A USEFUL INDICATION IF IT HAPPENS TO YOU.

SALUTES.
