My major concern is if the work was done well and right. Also if the ECU was reprogrammed and if it wasn’t can I damage anything. I have some pics. I also found out that DEF is disconnected and the O2 is unplugged
So i am purchasing an ecodiesel and my shop noticed that there is no cat or dpf. He said it looks clean install so we are both guessing previous owner bought a kit. I am trying to determine if it was done well and right. I am guessing that we should also check
DEF
ECU - piggyback or flash...
