Trafic preheating lamp and smoke issue
Summary of the thread
A 2019 diesel Renault Trafic with 198570 km is experiencing issues with the preheating lamp not switching off, the check engine light being on, and smoke during acceleration. Diagnostics suggest a defective glow control unit, possibly due to a cable or plug connection issue. The recommended solution is to have the vehicle inspected and repaired by a professional workshop to avoid further complications.

Yes, a diagnostic test was performed, which indicated the glow control unit as the source of the problem. The report suggests that the cable or plug connection of the component may be defective. Was your issue related to this component as well, or was it something else?

Yeah, that's it! Glow control unit! I remember now. I tried fiddling with it myself, but gave up pretty quickly. Honestly, unless you REALLY know what you're doing, I'd suggest getting it looked at properly. I ended up taking it to a workshop. Saved me a load of hassle in the long run!

Thanks for confirming. I appreciate the advice. Given the potential complications and the need for specialized tools, I will arrange a workshop appointment. The estimated repair cost is approximately 95€, which seems reasonable. I appreciate your help!

That sounds familiar. I've got a Trafic as well. Had the exact same thing happen a while back – preheating light staying on, engine light popping up, and a bit of smoke when I put my foot down. I thought the engine was gonna blow! Did you run any diagnostics?
