Eseries preheating lamp and check engine light
Summary of the thread
A 2009 Ford Eseries diesel is experiencing a persistent preheating lamp, an illuminated check engine light, and smoke during acceleration. Diagnostics suggest a defective glow control unit, with potential issues in the cable or plug. A similar issue in another vehicle was resolved by addressing a faulty connection to the glow plug relay. It is recommended to consult a professional technician to diagnose and repair the problem safely.

I haven't checked the voltage at the glow plugs. Could you explain how to test the voltage and what readings would indicate a fault?

Messing with a diesel's electrical system can be risky. I'd recommend a workshop. They can diagnose it properly and replace the control unit if needed. Better than frying something and getting a bigger bill!

Thanks for the guidance. Given the potential complications, I'll consult a qualified technician. It's best to leave this to professionals. The repair set me back 95€.

Sounds familiar! My old Opel Astra had the preheating light stuck on and the engine felt choked on acceleration. It was a dodgy connection to the glow plug relay. Did you check the voltage at the glow plugs?
