Seat Tarraco Diesel Preheating Lamp Issue

I am experiencing a problem with my 2019 Seat Tarraco diesel. The preheating lamp does not switch off. Could a defective glow control unit be the cause of this issue? Would a defective connection lead to these symptoms, potentially affecting car maintenance and causing vehicle stalling, especially during a cold start? Is this also causing the engine light to come on and smoke when accelerating due to a faulty heating element?

I drive a Seat Tarraco too. A similar issue occurred with my vehicle. Was the preheating lamp illuminated even after the engine was warm?

Yes, the preheating lamp remained on. Furthermore, the engine light came on, and there was smoke during acceleration. The error code indicates a defective glow control unit. The mileage is 168471 km. Could this be related?

Affirmative. In my case, the defective glow control unit caused similar symptoms. Considering the potential impact on engine performance, is it advisable to consult a workshop to prevent further complications?

Understood. The cable and plug connection of the glow control unit were indeed defective. The repair cost 95€. Thank you for your insight.
