@T5-T6-Schnappi checked everything, i mean everything. the card was already bought with DPF off ( he even received another ECU ( ecm ? ) , i dont know what's with that yet ) .
the car works perfectly, except for that problem I was talking about. I found out now that it only has DPF Off, EGR is not off, he doesn't know who made the software part for dpf off, but after all the checks he didn't find any mechanical cause for the problem, only the software part remained.
tomorrow I'm going to him and I'll do another check with vdash.
the question is, if he chooses to put software ( ORI + DPF Off) how do I proceed? any advice, is there anything else I should take into account? is there any way I can save the software that is now on?
thanks a lot !
