Talisman preheating lamp and check engine light

I'm having trouble with my 2019 Renault Talisman diesel. The preheating lamp stays on, the check engine light is lit, and it smokes when I accelerate. Diagnostics point to a bad glow control unit. I'm wondering if it's a cable or plug issue. It has 66295 km on it. Anyone else seen this?

I have a Talisman and had similar symptoms. Did it also potentially cause stalling?

It hasn't stalled yet, but I'm worried it might. Was your issue related to the heating element or cold start problems?

Yes, my issue was related to the heating element and difficulty with cold starts, pointing to the same control unit. I'd recommend getting it checked at a workshop.

Thanks for the information. Turns out it was indeed the glow control unit and a bad connection. Repair cost was 95€. Problem solved.
