hey, I don’t want to say that I have my dedra heize like the sow, even drive quite sparingly, but I can only dream of consumption values of 7.5 liters. drive mostly long distances. in addition, the empty speed when the engine is cold between 1200 and 1300, and if it is warm then 1000 or something under it. have already guessed that maybe the inlet valves could be quite over.. what else could this be? air filter is new. already thank you in advance edit. current consumption is between about 9 and 10 liters
