Hi, try this .

Your mixture is too rich. I wouldn't disable that fault code (P0172).
I would check what is causing that before you damage the engine.
Never mind the extra money you have to pay for fuel when the fuel usage is too much.

I would most certainly not switch the lambda off. That's the one thing that is keeping the mixture somewhat under control.
Without it the fuel usage could be way higher than now.
