Hi guys, I drive zafira with the z18xe the consumption was about always 8 liters and less.. Meanwhile used 10-15 liters I was at the FOH having read out error there were no insides that have something to do with the engine… spark plugs, air filters And oil are freshly changed. The combustion on the old spark plugs looked normal – a little sooty. Now I really don’t know any more I think it is LMM or Lambdas special defective. But was not displayed when error reading What can you do for now? Can you somehow test which part of it is? Or is there still other things that it can put on? I also have the feeling the more fuel-saving I drive the more it consumes.. So it’s a really strange problem. Hope any of you know what… Greeting Sascha
