Yesterday ? came from a colleague who has a workshop that brings work and clients, and he asked me closing the Egr ( to not clog up the swirl and lock ) and + sensitivity? throttle while wanting to maintain the Dpf. To me the thing ? played strange why? usually I associate closing the egr to the elimination of the dpf in order not to have problems with clogging and/or lack of regenerations.
Since? I do not want him to do damage, I would ask for your opinion on this what if ? secure or not, then will see? then to do that.
thanks
