Consumption in BC after heart transplantation

It was not here for a long time, it has changed a lot. Unfortunately I have at the moment so much to the ears that I hardly come here to read or even post. On the topic: The long-awaited operation seems to finally succeed today. My old Schindmäher got a new heart. (well, not new. But 100tkm younger). It was probably running smoothly according to the workshop, the engine runs nicely round, starts already almost before the key turning and also has a little more power. So almost al read well, at least what I can say after the first 15km with it. However, the BC shows with warm engine in the stand now 1.3l/h, earlier was the 0.9l/h. I can think of a temperature sensor for the MSTG that might not work properly. I can get that out thanks to OPcom. Or is there something else I should think about? Tomorrow the new engine has to suffer again, then the autotrailer has to get up again… Omi with Omi on trailer looks good, someone wants a photo se hen?
