Hello everyone, i own a 2019 Sportage 1.6 Crdi 136hp non hybrid and the following problem occured. After an ecu update by the KIA dealership, the engine temp drops by about 20C, every time at full load, pulling from 3rd gear or higher from 2000 rpm. At city driving and mild acceleration the temp gauge looks normal just below the middle mark. I logged the parameters with an obd tool and it looks like at high engine load the ecu opens the thermostat and and the egr valve at the same time, resulting the coolant temperature to drop suddenly. No check engine light or anything else while driving. DPF regenerations seem normal. The dealership says that maybe it will be resolved with a new update in the future and to not worry about. Has it happened to anyone else? Is this considered to be normal thermal management behaviour?
I attach my obd log, which happens to be during a dpf regeneration, but the coolant temp and egr valve behaviour is like this regardless.
