Stilo Preheating Lamp and Check Engine Light

Hey, I've got a 2005 Fiat Stilo diesel. Lately, the preheating lamp won't switch off, and the check engine light is on. Plus, it smokes when I accelerate. I read it might be the glow control unit. Any thoughts? I checked the cables and plugs and noticed some corrosion. Could that be it?

Sounds familiar. I had similar issues with my Stilo. Was the engine misfiring at all?

Misfiring? Not really, but it feels sluggish. Did you figure out what was causing it on yours?

Yeah, it turned out to be a defective connection to the glow control unit as well. If you have doubts about the diagnosis I would suggest going to a workshop and having a diagnostic test done.

Thanks for the help! I took it to the workshop, and you were right. It was a defective cable/plug connection to the glow control unit. Cost me 95€ to fix. Appreciate the advice!
