Consumption and smoke

Hello, I’ve been driving the new T 135 with 137 hp for nine months and about 8000 km. Mine starts to smoke when it’s really warm. So far the software has been restarted, the seal to the valve renewed and the EPR valve renewed. It didn’t help anything. I suspect a mistake in the injection because my transit with RV setup is not under 14 L/100km even with economical driving. The workshop has even driven a consumption of 19L/ 100 km. Has still j emand so good experience with the new TDCI engine?
