Hello and thanks for your question in the autoaid Community.
In the ECM there are 2 faultcodes:
4A5E GLOW PLUG CYLINDER 2, TRIGGER ERROR
452A PARTICULATE FILTER SYSTEM, ERROR
You should measure the wires from the glow plugs, if there is already okay, then you should replace all glow plugs. Because after one glow Plug these comes the next.
After this repair, look at the differential pressure Sensor for the Dpf. Look for the wires and hoses.
When ther is already okay, i think, you should replace this Part and erase the fault Codes.
Drive a while at 2000-2500 rpm, Because the Dpf will be regenerated at this Drive.
