Skoda Citigo engine overheating and communication error

I'm having a problem with my 2019 Skoda Citigo, gasoline engine, which currently registers 51126 km. The engine is exhibiting signs of overheating, accompanied by the check engine light. Furthermore, there is evidence of coolant expulsion beneath the vehicle. Initial car diagnostics suggest a control unit communication error. Is it plausible that a defective cable or plug connection to a component could precipitate such malfunctions?

Engine overheating in a Citigo, accompanied by coolant spills and check engine light? Sounds awfully familiar. Did you by any chance experience any issues that suggest CAN bus errors?

That's interesting. The CAN bus is something I was suspecting as well. Could you perhaps elaborate on the symptoms that led you to believe it was a CAN bus issue? Did you also experience control unit communication problems?

Indeed. The symptoms were strikingly similar: overheating, check engine light, and communication fault codes related to various sensors. Given the interconnected nature of modern automotive systems, a software glitch or CAN bus issue can manifest in myriad ways. While I am no expert, it would be prudent to have the wiring and control units thoroughly inspected.

Your input proved invaluable. Following your advice, I brought my 2019 Skoda Citigo to the workshop. The car diagnostics confirmed a defective cable connection to the control unit causing a communication fault, precisely as suspected. The repair cost amounted to 95€. The engine overheating issue and coolant spill are now resolved. Thank you.
