Thank you for your annual report, René. An experience I would like to share. I also had a very sudden increase in consumption two years ago. In my case it was the lambda sensor, that is the control sensor before the catalytic converter. In the OBD I could see that the voltage jump had become very sluggish, even before the engine light came on which did a few days later on. With a new lambda sensor, the consumption was again low and normal. Of course there can be other reasons, MAF sensor etc.
