V40 T3 Automatic – high fuel consumption when starting up

Hi Volvo friends. I need your support today, from drivers of a V40 with automatic transmissions. I drive a T3 (MY 2017) and have a fuel consumption of about 38.8 l/100km when starting up. This always occurs in the following situation: – The car stands level – I start the car and switch to D – now I only take the foot off the brake without touching the accelerator. So let the car roll up. – now the current verb also rises to up to 38.8 l/100km, but after some time sinks again to “normal” values. – an equally high consumption arises when starting/normal acceleration at traffic lights.My question therefore: Is this also the case with other automatic drivers or how high is the verb also in these situations with you? Note on the edge: My dealer has asked for this reason in Sweden and the Antwprt get, one may exchange the swimmer in the tank. He as well as I have to do with us and Sweden what the consumption should not have to do with the swimmer.
