2005 Ford Focus 1.6tdci Misfire with P0210, P0310, and P138B Codes - Smoke Issue Cures Itself After Driving

Model: Ford Focus Fault Code: P0210 Posted: 2012-07-15 13:07

Hi everyone, I'm looking for help with my 2005 Ford Focus 1.6tdci. The car is showing multiple misfire-related fault codes: P0210 (Fuel Injector Circuit Malfunction), P0310 (Misfire Detected on Cylinder #10), and P138B (Glow Plug Control Module Voltage Issue). The problem is accompanied by visible smoke, which seems to disappear as I drive longer—however, when I restart the car the next day, the symptoms return. This is confusing because my 2005 Focus has only four cylinders, so a misfire on cylinder #10 doesn't make sense technically. I'm wondering if this could be an ECU misreading or a wiring issue affecting the injector circuit. Any insights or suggestions would be greatly appreciated.
