Problems with the check engine light and starting difficulties

Hello everyone, I have a VW Transporter and am facing two problems: The check engine light is on and the engine is difficult to start. Has anyone had similar experiences or any tips on what could be causing this and how I can fix it? Thanks in advance!

T5, Multivan 2.5L, 96 kW. The engine control light is on. The error "circuit happiness candle one" is displayed, can be cleared but always returns. All "happiness candle" connectors and cables have already been replaced. The error keeps reappearing.

Check the glow plugs themselves, as a faulty glow plug can cause starting issues and trigger the check engine light. If they haven't been replaced recently, consider testing them for continuity or resistance to ensure they're functioning properly. Let me know how it goes or if you have any further questions!
