Very common with an aftermarket coolant heater as it raises the cold start coolant temp much higher than the stock block heater. Try just using the heater approx 1 hour prior to starting the engine so the coolant temp does not get too high

Thank you, now I understand what happens. But when its cold outside I would like to have a warm car. When I start the heater to early before startin engine, its already cold inside. Is there any other way to protect setting the trouble code?
By the way, you are the best expert i ever met, GM in Germany did not know anything about comparing the two temps. Really great!! Thank you
