Got a Peugeot 2.0 hdi 2012 fault code p1446 additive adding permanent.
Filled the fap system upto the brim and still wont clear. Diagnostic won't so the programming either due to fault code not clearing down any ideas

That should work you could also look on the planet map on the forum and see if there is a member near you who could do a code read and save buying the kit

I've used the diagbox today its showing as permanent fault still. Unable to clear faults, unable to tell it has been filled as it comes up unable to perform learning, any ideas which way to go on this as need to get to the bottom of this asap as it throws up on the dash risk of dpf clogging. Any help and ideas greatly appreciated
