Hey. Does anyone know how to make sure that the intake flaps are open? I am about to do the flaps delete and do not want to take everything apart. They were cleaned and operate normally (for now) but I am deleting DPF and probably would like to delete flaps and EGR with it. I just want to make sure they are stuck in the open position before disconnecting the motor and doing the delete. The car is 2011 ML350 Bluetec. Also maybe someone knows how to remove the DPF filter from the pipe or where to get a replacement pipe cheap.
