Hello @ivanmihov

I tested and I still have message "additive too low" and several dtcs
P2408
P1442
P1446
P1445

it's possible to make dtcoff.
Thanks for your help

try it,pass is the same

for low additive level,you might need to reset the level with diagnostic tool,lexia is the best for that

I tried with the second file but got a message still low additive and repair engine.
I reset the level with diagnostic tool diagbox.
But I have no fault in the engine ECU and the additive pump
an idea ?
