A2: Common signs of a faulty glow plug control unit include difficulty starting your diesel engine, especially in cold conditions, engine misfires, a "check engine" light illuminating, or diagnostic trouble codes related to the glow plug system. Q3: Can I replace a glow plug control unit myself?

It's often recommended to consult a professional mechanic for accurate diagnosis and replacement.
