For a year now this same check engine light comes on about 20 minutes after start of the truck and driving.

I checked the fault and its "Doser Fuel Line Pressure High"
Number 4077
Confirmed, active permanent

Any idea how to remove this by going into parameters?

(I'm guessing this was probably missed during the demandate process)

Thanks in advance

typical symptom of bad de-mandate programming.
get with Unilevers, Mommaburt, Mr.Hag, have the programming fixed if it is not too late already.. - bad programming always leads to a premature engine death.
