Yeah, it throws a code related to a control unit communication error, but I don't have the specifics right now. Is that what you were seeing? Did you fix it yourself?

A control unit communication error was exactly what I was getting. I tried fixing some connections myself, but it was a headache. I took it to a workshop. They found a defective cable or plug connection and charged me 95€.

Thanks for the insight! Sounds like I'm dealing with the same thing. I'll take it to a shop to get it checked out. Hopefully, it's just a defective cable or plug connection, nothing major. I'll let you know what they find. You've been a lifesaver!

Overheating and coolant spills are no joke! I drive a Sunny too. Your symptoms sound familiar. Does your scanner show any specific diagnostic trouble codes? It might give us a clue!
