Yes, I agree with this. The very first time I changed my coolant I did not know about the bung at the crossover tube. I was letting the car idle and noticed coolant overflowed and car went into limp mode. Hard lesson to learn, but nothing wrong other than not burping the system properly.Sounds like improper burping procedure.
Based on my experience, I do not think you hurt the car. These cars go into limp mode for various reasons (i.e. coolant issues, charging issues, etc.). And that's the reason they go into limp mode. Too protect the engine/various systems.Would driving it for about ten minutes yesterday. Damage anything. ? I didn’t know anything was wrong until I got on it a bit at 30mph
I think you just need to burp the cooling system properly and your car will be back to normal.
