Hi I got 2012/2013 2.2 diesel 129kw a month ago and did service and dpf clened. 180k km on clock. I have weird problem with fuel consumption. I reset computer and drive 30km straight at 95kmh ~1800rpm and got 5.5/100km. I watched momentary consumption and all was okay. But in random moment it doubles and next 30km is 10-11l/100km. I thought it was just sensor error cause car acts normal. I filled up the tank and drove 175km in speeds 95kmh to 125kmh and ~20% of this trip momentary showed these high numbers. Filled up and got 7/100km, computer showed the same. So i think its not just sensor reading error or something and its not dpf cleaning cycle. Any suggestions?

Or this can be dpf cleaning cycle?

 

Seems like dpf regeneration, but way too frequent.
