* Engine controller software out of date. ''See special notes''
* Replacement Fuel Injectors (Injector Quantity Adjustment (IMA) channels) not calibrated to engine controller
* Faulty Fuel Injector
* Low compression or engine mechanical issues
* Carbon deposits on Pressure Sensor/Glow Plugs including Cylinder specific Internal Pressure Sensor DTCs

==== Possible Solutions ====
* Check/Update Engine controller software. ''See special notes''
* Check Injector Quantity Adjustment (IMA) Adaptation channels
* Check/Replace Faulty Fuel Injector and calibrate IMA Adaptation channels
* Check the Engine mechanical condition in addition to the installed Pressure Sensor/Glow Plugs

==== Special Notes ====
* CR TDI engine controllers had several known software issues and dealer level flash updates over the years. Check the [[Official Factory Repair Information]] if your engine controller is not listed below:
** '''VW''':
