Hello I could't find any information regarding this problem. If I let my car running in idle the consumption on BC is continuously rising. This never happend until now. In 2 minutes of idle running it goes fron 8.7l/100km to 30l/100. Also I don't think that the consumtion is real. I'll do some runs to check the real consumtion. Before this, I've changed the air/oil filters and the EGR thermostat. Does enyone had a problem like this. Thank you in advice.

It's quite normal when your car is standing and your engine running the fuel consumption is an infinite number of liters/ 100 km since you aren't moving at all .. It's something normal with every BC in all cars.
RO: Pai daca stai pe loc consumul e ceva de genu infinit litri / 100 km fiindca in acest ritm nu vei face niciodata 100 de km ca sa poata fi calculat consumul si atunci calculatorul de bord face media la cat ai mers si cat ai consumat . E ceva normal la orice masina cu comp. de bord

Your consumption is constantly adapting based on your driving style, if you leave it running and not moving this would be 0MPG. I think the manual doesnt recommend leaving the engine to idle for long periods of time, its not good for it or the health of anyone nearby.
