If you can get hold of a OBII scan tool or go to a dealer you simply plug in the OBII socket and it'll tell you which GP's are faulty. It won't be a faulty Heater and I doubt it'll be the removal of your exhaust DPF. I'm about to remove my own DPF and have already run the "Green Diesel" delete code as a trial and have had no issues because of disconnecting the DPF. Be warned you must upload a DPF delete code or you will have many issues.
